“Semiconductor Market Update - Making Sense of the Data”
Abstract (English)

All the normal indicators we use to determine the health of the semiconductor industry look good. However, two significant and unpredictable factors are in play: COVID-19 and the US-China trade dispute. Clearly, these are not normal times, which means we should be looking at alternative data sets to help guide our decision making. This presentation reviews the industry's current state and explains what other types of information we can use to give an early warning of any shift in market conditions.

“Wafer Level MEMS Testing”
Michael Siebert
Abstract - Biography (English)

Currently almost all final test is done in stimulus test systems with pick and place handling, because this is needed when sensors are packaged in traditional packages. Applying these pick and place solutions to small CSP packages with sizes of 1x1mm or even smaller introduces challenges that can be avoided when final test is moved to a wafer probe station that allows testing under stimulus.

Our talk explores the advantages of wafer level test in regards to device performance and benefits for manufacturing at the test floor.

Michael has more than 25 years of experience in the semiconductor industry and is currently holding a position as Director Sales and Marketing with Afore Oy, a Finland based provider of application specific test solutions for MEMS and other semiconductor devices.

Abstract - Biography (English)

“The wide spectrum of SOC and SiP devices are driving a large range of DUT power supply requirements. Power supply requirements range from low power 1 Watt per device with up to 5 different voltages to high end GPU/Processors with switching requirements from 10 Watts to more than 150 Watts within a few microseconds.

Users can address the low power requirement with ‘off the shelve’ instruments and most ATE systems. However, the high-power coverage is still limited to a small number of high end solutions manufacturers.

Considering that only dedicated amplifiers can cover the need for high power devices, the traditional answer it to populate scarce and expensive ATE slots with a suite of high-power Device Power Supply’s.

Mu-Test, an AEM company, is addressing these challenges by developing a unique Power supply module that covers low power/high accuracy and High power device needs while maintaining the required signal fidelity at an affordable cost.

This paper will share the requirements, technical challenges, solutions and supporting data to address these demanding device power supply challenges.”

“High-power test challenges for AI and high-performance processors”
Beck Yu
Abstract - Biography (English)

Advanced process large-scale chip products such as AI applications are constantly driving the power output capabilities of test platforms. Many products for the server high-performance computing market have power consumption as high as 400w. In ATE (Automatic Testing Equipment) mass production testing, the higher Toggle rate will even reach several times the peak power consumption. The constantly evolving test trend also requires that test solutions need to increase test parallelism as much as possible, increase support for more power rails and parallelism, and thus reduce processing costs. In addition, the lower and lower core voltage also puts higher and higher requirements on the output accuracy and dynamic response of the power supply.

This presentation will discuss the power supply challenges encountered by current high-performance processors and AI products, and how to deal with these challenges in terms of mass production. It will analyze and interpret different power supply test challenges for several different test scenarios: high density and high parallelism, high current and low voltage, and high dynamic response performance.

Beck Yu is positioned as Field Product specialist at Teradyne China Sales team, focus on fields like Digital, RF, Power, Mixed signal semiconductor testing solution design & development and product marketing support.

“ATE Challenges on Sub-6G PA ”
Norris Wang
Wei Xu
Takumi Hayashi
Zhiqiang Bai
Abstract - Biography (English)

Sub-6G RF TRX system is hot spot in 5G communication. Compared to mm-wave band (FR2), sub-6G (FR1) band has a lower power consumption and larger cover range. Compared to traditional 3G/4G Front End Module (FEM), sub-6G FEM also brings challenges like obvious occupied band-width increase (10M/20MHz-> 100/200MHz), higher order modulation (64QAM -> 256QAM). At the same time, the efficiency of Sub6G Power Amplifier (PA) is reduced fiercely. The biggest question we faced in the Sub6G PA is the thermal degradation caused by extremely low power added efficiency (PAE) in ATE test condition.

Our ATE test environment were established on the latest Advantest SmarTest8 (SW) and V93K tester (HW). Compared to customer’s environment, ATE test environment works with higher density (WSRF card), shorter time, worse heat dissipation, multiple RF connectors and attenuators. Worse heat dissipation means EVB-IC is welded to EVB PCB, larger contacting GND(6-Pads) exists on EVB while ATE use two socket pogo as GND. PA active current was over than 1A at an output power 26.5dBm without no additional heat dissipation method. Shorter time: customer-RD does not care about the test time in their side, what they want just accuracy results, while ATE cares much about the test time.

Critical ATE test environment and tight schedule, but we still need to ensure correct test results, a careful correlation scheme is essential and been well designed. This article explains how to overcome the non-convergence of the reference calibration current, how to reproduce the results of calibration and FT, and how to ensure the robustness of the results of mass production testing from the perspective of engineering and production. We hope this article will be helpful to the other similar ICs engineering practice and rapid introduction.

Norris Wang, born in 1989,12. Graduated from Tongji University in 2015 with a master's degree in Physics and Science. 2015-2019, RF application engineer (ZTE/Thundersoft). 2019-3, joined Advantest Shanghai as ATE engineer.

摘要 (Chinese)


我们的ATE测试环境建立在最新的Advantest SmarTest8(软件)和V93K测试机台(HW)上。与客户环境相比,ATE测试环境具有更高的密度(WSRF板卡4site同测)、更短的时间、更差的散热(几乎没有)、多个射频连接器和衰减器。散热差意味着EVB-IC焊接在EVB-PCB上,EVB上存在较大的接触GND(6-Pads),而ATE使用两个插座pogo作为GND,在我们遇到的实际案例中,在没有附加散热措施的情况下,DUT输出功率为26.5dBm时,DUT工作电流大于1A。ATE永远面临着尽可能减少时间的问题,而客户的研发并不关心他们的测试时间,他们想要的只是准确的结果,这也给我们做数据对齐带来了很大的挑战。


“RF Simulation Technique for high speed test socket”

Abstract - Biography (English)

The rise of Internet of Things, 5G, artificial intelligence, autonomous cars, Deep Learning, self-driving vehicles have increased consumer demand for products requiring higher speed digital and analog Integrated Circuits (ICs), therefore, the demand for designing high performance test sockets must keep pace.

In this paper, we will discuss the challenge of RF simulation and will focus on a new Enhanced Simulation Technique that can improve the accuracy of simulation, validation methods with advanced measurement to show correlation study between simulation and actual measurement

In Signal Integrity simulation, HFSS software is commonly used especially for high frequency. As Data rates and Bandwidth continue to increase, a paradigm shift is emerging in the industry which is driving socket suppliers to provide more detailed simulations to include the Device Package and PCB interfaces in the analysis. It is critical that the socket impedance is matched as closely to the PCB impedance for maximum performance.

VNA measurement verification. A Vector Network Analyzer play a key role to achieve correlation between simulations and measurement, The VNA measures the amount of energy transmitted through the DUT and reflected by the DUT at different frequencies. It then provides these results in scattering-parameter (S-parameter) of the entire test setup. The test socket is then de-embedded and gated to try and provide basic performance data, such as the -1 dB Insertion Loss (IL), -10 dB Return Loss (RL), Loop Inductance (L), Mutual Capacitance (Cm) IL, without the effects of test fixtures and PCB.

In conclusion, SI simulations using HFSS become critical in developing new high-speed test sockets. Extensive simulation can reduce development time. More importantly, optimized simulation methodology by including package and test board structures can generate more accurate or reliable simulation results.

Khaled Elmadbouly is a Signal Integrity Design Engineer with Smiths Interconnect. He has twenty-five years of experience in semiconductor front and backend testing process include PCB design, high speed device contactor, and HFSS Signal Integrity simulation. He earned a BSEE degree from San Jose State University and a BS Mathematical Statistics from Cairo University.

“High-Speed Serial Testing Goes Beyond Loopback”
Doug Malech
Choung Huynh
Abstract - Biography (English)

Traditionally, serial I/O ports have been tested using loopback methods, where the transmit port is connected to the receive port and internal BIST algorithms are used by the device to test itself. With the newest generations of high-speed port testing including 56Gbd PAM4, devices need to be better characterized to prepare them for a more challenging environment. Rather than loopback alone, external sampling scopes and BERTs can be used to test these devices more thoroughly with additional data collection that offers potential for better device margining, more thorough data sheet specification checking and troubleshooting beyond pass/fail testing. MultiLane will present data to compare a device tested by loopback-only versus the same device tested using a MultiLane BERT and Scope to show the benefits of breaking with the paradigm of loopback-only testing.

An Advantest V93000 including a Multilane high-speed option will be used to do the comparison. A loadboard was designed to simultaneously test two of the same high-speed devices; one device using traditional loopback and one device using Multilane scopes and BERTs to do more complete testing. This real data will be shared in the presentation and pertinent simulation data will also be shared. The presentation will also go into the mechanics of connecting the scopes and BERTs to the loadboard and into how to de-embed the 56Gbd PAM4 signals.

Doug Malech has 30 years in various engineering design, sales and marketing roles in both ATE and semiconductor companies.

摘要 - 简介 (Chinese)

传统上,串行I / O端口是使用回环方法进行测试的,其中发送端口连接到接收端口,并且设备使用内部BIST算法对其自身进行测试。随着包括56Gbd PAM4在内的最新一代高速端口测试的出现,需要对设备进行更好的性能表征,以便为更具挑战性的环境做好准备。不仅可以单独使用环回,还可以使用外部采样示波器和BERT通过附加数据收集来更彻底地测试这些设备,这些数据可以提供更好的设备保证金,更彻底的数据手册规格检查以及通过/失败测试之外的故障排除。 MultiLane将提供数据,以比较仅环回测试的设备与使用MultiLane BERT和Scope测试的同一设备,以展示突破仅环回测试范式的好处。

比较将使用包含Multilane高速选件的Advantest V93000。负载板旨在同时测试两个相同的高速设备。一台使用传统环回的设备,另一台使用Multilane示波器和BERT的设备进行更全面的测试。此真实数据将在演示中共享,并且相关的模拟数据也将共享。该演讲还将探讨将示波器和BERT连接到负载板上的机制,以及如何去嵌入56Gbd PAM4信号。
