“The Future of Advanced Packaging: Meeting the Challenges”
Jan Vardaman
TechSearch International, Inc.
Abstract - Biography (English)

The high cost of moving to the next semiconductor technology node is changing the role of packaging and assembly in the electronics industry. New packaging solutions are being adopted to achieve the economic advantages that were previously met with silicon scaling. These options include silicon interposers, fan-out wafer level packages, and system-in-package. Some high-performance options are considered homogeneous integration, where die are partitioned. Others are classified as heterogeneous integration, including solutions in which some die functions are fabricated on the latest nodes, combined with other die fabricated on older less expensive nodes and linked together in the package. Combinations of memory and logic in the same package are increasingly common. Substrate warpage remains an issue and the need for known good die is becoming increasingly important. Test considerations factor into package choices. This presentation discusses the packaging changes and how the industry is addressing these challenges

Abstract - Biography (English)

In this presentation we will discuss the challenges of over the air testing (OTA) of DUTs with Antennas in Package (AIP). The topics that will be discussed are:

  • Near Field vs Far Field Measurements
  • OTA Challenges for ATE
  • The Surrogate Package Concept as verification vehicle for OTA
  • Types of Measurement Antennas
  • Limitations of Single Antenna Socket Approaches
  • Probing in the antenna reactive nearfield

The above topics will be discussed using measured data from a surrogate package designed with antennas in the package to serve as evaluation vehicle. Because this surrogate package designed by Advantest has no silicon, only the antennas is the package is an ideal demonstration vehicle. There is no IP restrictions on the measured data with that surrogate package making it an ideal vehicle for comparing different OTA testing approaches

Jose Moreira is a senior staff engineer in the HW R&D Team of the SOC business unit at Advantest in Böblingen, Germany. He focuses on the challenges of testing high-speed digital, silicon photonics and 5G mmwave devices, especially in the area of PCB test fixture design, signal and power integrity, measurement techniques and focus calibration.

Abstract - Biography (English)

The world is connected in the digital data era with novel mmWave applications, such as 5G and WiGig, which will drive the dramatic demand of high performance for 400 Gbps Ethernet instrument. The original modulation technique based on Non-Return-to-Zero (NRZ) encoding cannot provide enough effectiveness to process the increasing volume of data. Therefore, 4-Level Pulse-Amplitude Modulation (PAM4) application doubles the density of data in serial data transmissions by increasing the number of levels of pulse amplitude, which leads to a possible and cost-effective development for the networking infrastructure. However, the Signal-to-Noise Ratio (SNR) of PAM4 is worse than NRZ and needs a better cross-talk reduction with better mechanical characteristics for mass production.
In this presentation, we have worked with Tier-1 customers in the world to test 112Gbps PAM4 chips with pitches ranging from 0.5 to 0.8 mm. If we compare test results among the coaxial socket, short probe and elastomer solution, the short probe and elastomer solution are common test solutions to fulfill the high-speed requirement. However, both contact methodologies would not be adequate for mass production. Brownie socket* has unique design of the coaxial structure where insulated composite is embedded. Compared with other existing coaxial solutions, Brownie is capable to be manufactured for the fine pitch coaxial socket.
To analyze the socket performance, we have done the socket simulation alone based on the high-speed area of the device. The result of socket itself shows the insertion loss around -0.2dB, return loss around -16dB, and crosstalk <-50dB @28GHz. In order to have better understanding of channel signal loss, we have been working on the channel simulations of the socket and critical traces of the PCB for comparing with actual measurement results. Based on the test results, three kinds of sockets can pass at 56Gbps level and their performance is about the same. However, for 112Gbps PAM4, coaxial socket is better than short probe in the eye opening and has longer contact travel with better contact stability in the production environment. On the other hand, elastomer does not have clean eye opening for zero Bit Error Rate (BER) at 112Gbps PAM4.
In summary, coaxial socket is a proven mass production solution for 112Gbps PAM4. Both electrical and mechanical characteristics of coaxial sockets meet the testing requirements.

Collins Sun received his PhD of physics from National Sun Yat-Sen University and was senior R&D Manager at WinWay Technology, who is in charge of new product development and technology research.

摘要 - 简介 (Chinese)

世界变成了毫米波的数据时代,如5G和WI Gig,它推动了400 Gbps Ethernet 仪器的巨大需求,原有的Non-Return to Zero (NRZ)已不能满足要求,因此,PAM4变成了网络架构的主要数据传输方式,但是PAM4的信号噪音比不如NRZ,需要在机械装置中减小Cross talk 噪音)。
本文将介绍112Gbps PAM4 芯片 (0.5~0.8mm针脚) 的测试,比较了同轴结构,短针和导电弹性胶。短针和导电弹性胶可以满足高速的要求,但大量生产中不能满足机械接触的要求。Brownie 测试座是注入绝缘体的同轴结构比较其它现有的同轴结构,Brownie使小阵脚的同轴测试座成为可能。
采用了芯片高速进行测试座高频性能的模拟Insertion Loss,~ -0.2 dB, return Loss 16dB, cross talk < -50 dB @ 28GHZ.又进行了测试座通道和PCB的模拟,并与测量结果比较,根据实验结果,三种类型的测试座可以通过56Gbps, 但是, 112Gbps PAM4,同轴结构要优于短针并因更大的压缩长度而接触更可靠和稳定,另一方面,导电弹性胶在112Gbps PAM4的银圈上没有明显的张开区域。
总之,同轴测试座已证明是112Gbps PAM4 芯片大批测试中的解决方案,固同时解决了电和机械的芯片测试性能要求。

“Cooling Solution for the IC Device Testing”
“芯片测试中的冷却问题”

Abstract - Biography (English)

Semiconductor industry has made great progress in past 20 years. Nowadays the chips are fabricated with billions of transistors and these transistors generate much more heat which cause high heat power dissipation. So chip cooling has become a big challenge for IC Test Industry. In this article, some typical cooling solutions will be introduced, such as metal heatsink cooling, fluid cooling & chiller, heat pipe cooling, etc.
Air Cooling
Heatsinks (HS) always touch IC and press onto socket/PCB to test. For lower power IC test, free air goes through HS tunnels to chill the system. For higher power IC test scenario, HS can’t meet our Temperature request, then it is needed to add an electronic FAN on HS to force cooling the IC Test system.
Water cooling
Heatsinks still can be used in water cooling. Additionally, HS have more tunnels design in its body for water flowing; the tunnels can be made as: series, parallel, pseudo-series, pseudo-parallel. Heat dissipation for HS with water tunnel can overwhelm the air cooling one.
Another method is to add a chiller system to improve the heat dissipation ability for the thermal management proposal.
Heat pipe cooling
HS can be a part of heat pipe cooling system. HS body has several heat pipes inserted upwards. It is the evaporation and condensing of the water that forms a pumping action to move the water (and thus the heat) along the pipe.
Challenge Heat pipe cooling
HS can be a part of heat pipe cooling system. HS body has several heat pipes inserted upwards. It is the evaporation and condensing of the water that forms a pumping action to move the water (and thus the heat) along the pipe
Challenge
The future IC test power will be as high as 1000W or more, then new lid cooling system is a direction of research; Socket cooling ability is still not proficient
Space;
Cost.

摘要 - 简介 (Chinese)

在过去的20年里面,半导体工业有了一个长足的发展。如今的芯片包含动辄上十亿的晶体管,如此多的晶体管聚集在一起它们的发热量不容忽视。所以如何给芯片降温就是一个很大的挑战。
本文将介绍几种典型的冷却方法,其中包括金属散热片冷却,水冷和冷却器,热通道管冷却,等等。
*_风冷_*
散热片通常是和芯片直接接触并将芯片压入测试插座或电路板,并最终完成芯片测试。对于低功耗的芯片,空气通过对流通过散热片的鳍片并对系统进行冷却。对于高功耗的芯片,凭借单一的散热片通常达不到控温的要求,这时就需要增加风扇来强制增加风速,从而达到更好的制冷效果。
*_水冷_*
散热片同样也可以用于水冷方式。而且,水冷的散热片设计包含更多的流通通道来保证液体的热量充分交换,这些通道可以设计成,串联,并联,伪串联,伪并联方式。水冷是一种非常高效热交换方式对比风冷的方式。
另外一种方式就是增加制冷器来提高散热的能力,
*_热通道管冷却_*
散热片也可以是热通道冷却系统的一部分。 散热片本体被多个热通道向上接入。正是水的蒸发和冷凝形成了泵送作用,使水(以及热量)沿着管道流动。
*_挑战_*
* 将来的芯片功率可能高达1000W或者以上,所以新的散热方式任然在探索当中……
* 测试插座的散热方式正在捉襟见肘。
* 空间,
* 成本

MEMS Pressure Sensor Testing Solutions and Challenges
Thanks to MEMS (micro-electromechanical systems) technological advances, the applications of automotive electronics, consumer, IOT, mobile device have become more flourishing. MEMS pressure sensors already gained a foothold in market and played an important role in navigation, Quadcopter, environmental monitoring and TPMS… applications. Due to the huge demand for pressure sensors, develop testing and calibration solution to keep abreast of deal with new developments in the MEMS sensor.
This presentation will introduce our achievements of testing calibration systems for MEMS pressure sensor. How to control temperature and pressure will be crucial factors in the MEMS pressure testing, we have to face more challenges of soaking time reduction, chamber temperature uniformity, high pressure chamber design, leakage issues and stable time. The temperature close-loop control and cooling system are used for the purposes of optimal soaking time. In this system, precise temperature control and efficient cooling system become more important. In addition, chamber can fine-tune temperature offset for each area by modular temperature control unit, that temperature uniformity within +/-1⁰C had been achieved. For pressure chamber stability, reliability and leakage, we improved the chamber design to give greater strength and rigidity. Chamber volume is a trade-off between pressure stability and response time for different pressure conditions; Chamber volume problem are simulated, which proves optimization of pressure control time and accuracy.
As previously mentioned, this system has multi chambers for different temperature conditions and also control the heat loss that will make good performance to pressure sensor. For efficient mass production, multi chambers simplify the process of high/low temperature testing, and that reduce the opportunity for operator error.

Cheng-Wen "Hank" Yao currently is Department Deputy Manager of Advance Technology Development Division of King Yuan Electronics Co., Ltd. He has worked for KYEC over six years since he received his Master of Science (M.S.) Electronic Engineering degree from National Ilan University and is responsible for MEMS testing technology development. His experience includes integration of software and hardware systems for MEMS testing solutions for mass production of accelerometers, gyroscopes and pressure sensors, and magnetic sensors.

因微機電製程的進步使得微機電傳感器 (MEMS Sensor)的之應用發展日趨蓬勃,舉凡汽車電子、消費電子、移動裝置、互聯網等都脫離不了其應用範疇。而利用微機電系統技術所製造之壓力傳感器,更已在市場中佔有一席之地,諸如車用導航、四軸飛行器、環境監控、胎壓計等應用都有著密不可分關係,也因此對於製程的進步讓在MEMS測試技術與校正環境的建置開發上則顯得極為重要。
本文將介紹微機電壓力傳感器的測試與校正環境開發與實績,在壓力傳感器測試裡溫度與壓力控制是整體測試關鍵指標,其中挑戰在於腔體機構中影響升降溫時間、均溫性、高壓腔體、漏氣率以及壓力穩定時間等因素設計。
在多腔體機構設計上,首先,溫度控制部份是透過溫度回授感測與散熱系統來縮短升降溫的時間,而精準溫控變化與散熱效率將為關鍵;設計中對腔體的均溫性採用控溫模組來進行各區域微調以達+/- 1℃內;再則,壓力測試部分則強化腔體機構設計增強壓控穩定度與可靠度,減少漏氣產生,透過模擬腔體容積優化實驗,取捨於壓力穩定與反應速度上,讓壓力精準度與測試時間成本達到最佳化。
以上設計乃將大幅提升傳感器的效能,透過模擬溫度傳導減少散失與機台上多腔體變化排列,簡化了各腔體升降溫流程減少人為造成之異常,提升整體生產效率。

“HAST In-Situ Electrical Tests Down-to Pico-Ampere Range”
“皮安级别的现场电气加速寿命试验”
Yi-Ming Lau
STAr Technologies
Choon-Leong "CL" Lou
STAr Technologies
Abstract - Biography (English)

The traditional method of Highly Accelerated Stress Test (HAST) or Temperature Humidity Bias (THB) is to stress the devices at high voltage, high temperature and high humidity chamber. Devices are then powered down and cooled back to room temperature at intermediary predetermined stress time to be tested at ambient conditions by an external electrical test system. Once the electrical characterization is completed, the devices are put back to the chamber and powered back again to the stress voltage at HAST or THB conditions for the next cycle of stressing.
This qualification process ensures the devices tested are not affected by degraded DUT boards, sockets, interconnects and cable assemblies inside the HAST chamber. This process is not only time consuming, but more importantly, are extremely laborious and lack missing real-time electrical test results on the functionality and performance of the devices during stress.
There are more devices requiring low-level leakage current measurements and high voltage stress. To date, there are no known DUT boards, sockets, interconnects and cable assemblies that can work in HAST or THB chambers that are capable of high isolation. This is especially so for electrical measurement requiring pico-Ampere leakage current under high temperature and humidity conditions. As such, no electrical measurements or characterizations can be done in-situ during the HAST and THB. This further means that there is no immediate accessibility of precision electrical data throughout the stress cycle.
In this presentation, we put up a qualified set of DUT Boards, sockets and cable assemblies that are fully capable to work under high temperature and high humidity conditions, and yet still able to provide low leakage electrical measurements with leakage down to 10pA/V level. Each of these parts are independently qualified and put together as a burn-in interface under HAST and THB without much degradation and thus will not impact the actual in-situ test of DUTs during stress.
In this presentation, we will also show the results in-situ electrical measurements throughout HAST and THB, even down to pico-ampere level measurements. The DUT interfaces are designed and developed with proven data to be able to provide low leakage electrical characterization, and continuous electrical monitoring capability under high temperature and humidity.
With this system and setup, users would not only be able to have the electrical data to understand the changes of the devices throughout the qualification process, but also save the time and uncertainties induced on the devices after powered down and transferring of the devices to another system for electrical measurement after each stress cycle.

摘要 - 简介 (Chinese)

皮安级别的现场电气加速寿命试验
传统的HAST(加速寿命试验)或者THB(加速式温湿度及偏压测试)都是用高压,高温度和高湿度腔体的情况下完成加速测试。然后,通过外部电气测试系统在相关的环境温度中根据中间预定应力时间,关闭设备电源并冷却至室温。一旦电气特性测试完成后,这些芯片将被放回试验腔体里面,在HAST或THB条件下再次通电至加速电压,以进行下一个应力循环。
该认证过程确保被测芯片性能不受HAST试验腔体里DUT板、插座、互连和电缆组件的弱化影响。这一工艺不仅耗时,而且更重要的是,非常费力,而且在加速测试条件下缺少设备功能和性能的实时电气测试结果。
越来越多的芯片需要低水平的漏电流测量和高电压加速测试。到目前为止,还没有已知的DUT板、插座、互连和电缆组件可以在HAST或THB室中表现出高隔离度的性能。特别是在高温和潮湿条件下需要皮安级别漏电流的测量。因此,在HAST和THB期间,很难在现场进行任何电气或表征化测量。这进一步意味着在整个加速实验周期内,无法直接获取精确的电气数据。
本文介绍了一套合格的DUT板、插座和电缆组件,它们完全能够在高温和高湿度条件下工作,并能够提供低泄漏的电测量,漏电流水平低至10pa/v。每一个部件都是独立合格的,并在HAST和THB下作为老化接口组装在一起,不会有太大的性能弱化,因此不会在加速实验期间影响DUT的实际测试效果。本文还将展示整个HAST和THB的现场电气测量结果,甚至可以达到皮安级别。DUT接口的设计和开发经过大量的数据验证,能够提供低漏电流的特性,以及在高温和湿度下的连续电气监测能力。
有了这个系统,用户不仅能够获得电气数据来了解整个认证过程中芯片的变化,同时也节省了每一个加速实验周期结束后,将设备断电并转移到另一个系统进行电气测量所产生的时间和不确定性。

“Embedding Reliability for Zero Field Failures”
“利用嵌入可靠性的方法来有效实现零缺陷”
Nigel Gordon Kissaun
ELES Semiconductor Equipment
Abstract - Biography (English)

Several technology market trends are driving semiconductors to more stringent reliability requirements. The continued pervasion of electronics in automotive due to electrification, connectivity and autonomous driving is increasing dramatically the number of ICs in each car. This is coupled with an increase in chip complexity and pressure to shorter time-to-market cycles. Also, as is well known, Integrated Circuits reliability follow the bathtub curve. In its central region, the bathtub curve has the lowest, approximately constant, failure rate. Failures occurring in this region are defined “random” and are not detected by the traditional test flow (Final Test + Qualification & EFR test). As shown in literature, the majority of these, called “intermittent failures”, may be activated and deactivated by voltage, frequency, and operating temperature variations, in other words by stress conditions. The existing IC qualification flow and testing flow during manufacturing are no longer adequate to meet the higher functional safety or mission critical requirements. Even a 1ppm failure rate is too high. Not detecting random and intermittent failures, for such applications the traditional reliability flow and traditional test flow are therefore not suitable, obliging to adopt mitigation strategies such as redundancy. This paper describes a holostic reliability test approach called RETE (Reliability Embedded Test Engineering), which encompasses aspects from both AEC-Q100 and AEC-Q004. It starts with DfRT (Design for Reliability Test) at Design stage, a strategy for TFR (Test for Reliability) implementation, and data analysis to support a Learn-from-Fail feedback cycle. Practical applications of RETE to different semiconductor segments are described, supporting the road to zero defects.

摘要 - 简介 (Chinese)

市场的趋势要求半导体芯片具有更高的可靠性,汽车自动驾驶及其他电子功能大大增加了汽车里半导体芯片。同时,芯片的复杂程度亦增加,又要减少芯片研发至投入市场的时间。集成电路的可靠性类似浴盆形成,中央区是最低且平,相当于稳定的失效率。在该区的失效可定义为“随机”。传统的方法很难测定。众多文献上描述为“间歇式失效”,可能由电压的开闭和效率及温度有关,或称之为“应力条件”。现有的测试方法不再满足功能安全的要求,1PPM的失效率都太高。

Limited quantity of first article silicon and customer reference board (CRB) to support silicon debug or test is a challenge in semiconductor industry today. Semiconductor manufacturer did not produce huge quantity of first article silicon due to technology instability and involved huge manufacturing cost. The situation become more challenging when the manufacturer extended the debug/test coverage to their customer, example shipping limited silicon to their customer who resides in different geographical location which may caused up to weeks of delay and impact the overall time-to-market (TTM).
Current Technology Limitation:
Some 3rd party remote access software like TeamViewer & VNC were used by the manufacturer to establish a virtual debug environment with their customer to address the silicon/CRB limitation issue. Typically, these connections are done thru a non-secure internet connection and may lead to Intellectual Property (IP) leak.
Solution:
Intel has come out with a breakthrough solution by introducing a cloud based remote debug (CBRD) infrastructure which allow external customer to have first-hand access to first article silicon debug. The entire CBRD concept is to establish an end to end debug experience to all the user, which covers connectivity, CRB configuration/setup/booking system, remote debug experience and automated testing capabilities. This solution consists of 2 major architectures: Secure Access & Board Farm. CBRD applied 4 layers of Multi Factor Authentication (MFA) for secure access. Each user will need to register in Intel database to obtain an online certificate & login credential to establish a secure VPN tunnel to Intel’s environment. Board Farm architecture consists of asset management system, platform scheduling system with auto OS provisioning and extensive remote debug features such as remote power cycling for a platform, remote DC & RF signal probing & BIOS post screen access & debug. Individual debug environment can be create by the administrator on the fly. CBRD operates in 24x7 and allow user to perform debug activities remotely, anytime and anywhere. With this solution in placed, early bugs or sightings can discovered and Intel can response to the fix in a much more early stage to reduce the number of silicon design stage – a new agile way for silicon debug process.
Conclusion & Implementation:
This solution is able to improve the silicon debug process by weeks, reduced the total numbers of CRB and first article silicon produced per project (>50% hardware cost savings), improve the lab operation to 24x7 (improve utilization) and accelerate the time to market for a new product release. Intel has received a huge demand from customer to extend this capability across the globe.

Abstract - Biography (English)

IC test engineer like to using inductance and capacitance for socket model to debug and run analysis for their circuitry. This is simple way to evaluate the socket performance base on the extracted value of lump RLC. And most of the time the inductance plays more important role compare with capacitance.
In this paper, we report a basic study on various ways to extract the inductance of a socket model, and discuss the difference across varies math models.
Next by study a Saw filter application case, we discuss how correlation of these models compare to embedded s-parameter. We proposed several designs base on the embedded s-parameter math model to improve the socket. The experimental results confirmed the simulation data and proven embedded s-parameter is more correlated the real test result, and provide better prediction of socket design change.
