BiTS 2016 Archive Program

Hopefully you didn't miss a minute of the BiTS 2016 Technical Program, with eight jam-packed sessions plus a poster session with presentations by test and burn-in experts from around the world. This is complimented with an excellent Tutorial on Sunday, the ever-popular BiTS EXPO, and numerous networking and social events.

With more excellent presentations than could fit in the schedule, the Program Committee was challenged to assemble the BiTS 2016 program. We hope that you enjoy the best available presentations and posters covering all aspects of test and burn-in.




Please see the entire schedule below...


Tutorial Day
Sunday March 6, 2016
noon - 6:00 PM
Tutorial
Adaptive Test, Outlier Analysis, and Burn-In reduction/elimination
Jeff Roehr
Jeffrey Roehr
Senior Member of Technical Staff
Texas Instruments

This tutorial is designed to give attendees useful and practical information on the theory and statistics that support the application and use of Adaptive Test (AT) and Outlier Analysis (OA) in the production of modern semiconductor devices. In addition to providing information on the technical background behind these methods, the tutorial will include discussion of papers and case studies of real world applications of these techniques, emphasizing Burn-In elimination or reduction in production testing.

The goal of the tutorial is to provide attendees with the information and knowledge that they need to understand how (and when) AT & OA strategies are effective, the risk/reward relation implicit in these methods, the basic constraints and limitations of their use, and to walk away with the ability to implement fundamental techniques on their own. Sources of the material for this tutorial include personal experience, as well as extracts and references to papers and reports published by Universities and companies such as IBM, Intel, Analog Devices, LSI Logic, AMD, NXP, and Texas Instruments. Resource links to a variety of technical papers, authors, and 3rd party software vendors will also be provided as part of the tutorial materials.

The tutorial will be led by Jeffrey Roehr who is a Senior Member of the Technical Staff at Texas Instruments, a 35 year veteran of product and test engineering, and a Senior Member of the IEEE.

Note: Attendance at the tutorial will be limited. Please sign-up early to not miss out!

Jeffrey Roehr has over 35 years of experience in Product and Test Engineering and Management for RCA, GTE, Analog Devices, Mediatek, and is now working for Texas Instruments in Houston.

For the past 15 years his focus has been on developing algorithms for adaptive testing, outlier elimination, and statistical testing on very high volume production products.

Mr. Roehr has presented many papers, tutorials, and invited talks at IEEE events. He is a Senior Member of the IEEE, a member of the IEEE DATA Workshop Steering Committee, a member of the ITRS Adaptive Test working group, and is the founder and chairman of the Texas Instruments Data Analysis Workshop (DAW).

Chip Overtest
Are ICs Tested too Much?
Dale Ohmart
Dale Ohmart
Texas Instruments
We need to define test differently. It is easy to fall into the trap of considering test to mean "prove every part shipped is good", and then one step further to "test must verify all the specs of the part to ensure it's a good part". But this thinking leads to ever increasing test complexities and spiraling test costs. A better way to look at test is that the semiconductor manufacturing process builds defects and test is a sorting process to eliminate those defects from the shipped population. Test cost and test capital trends in the semiconductor industry will be examined with a discussion on how much test is affordable. What are the real-world limitations to test throughput? Are there "optimal" target values for test time and multisite count? What are the impacts of test on device yield? And how does the test process itself impact its own intrinsic yield? In addition to exploring these questions, do new requirements, such as non-electrical test and 3D assembly, also change these "answers"? Many thought provoking questions will be covered in this keynote, which will change how you think about test!

Dale Ohmart is currently a Distinguished Member of the Technical Staff at Texas Instruments, where he is focused on driving test manufacturing excellence throughout the company. He joined Texas Instruments after graduating from the University of Kansas in 1980 with his Bachelors of Science degree in Engineering Physics. He was awarded "Outstanding Senior in Physics and Astronomy" that same year and remains a proud "Kansas Jayhawk".

Throughout his career, Dale has contributed at Texas Instruments in a variety of positions from his first role as Product Engineer onwards. He was quickly promoted to Test Engineering Manager for the Microprocessors group in 1981 and has been involved in test within the organization ever since.

Dale has had many significant accomplishments during his tenure at Texas Instruments. He was instrumental in developing TI's current approach to managing test equipment productivity, he invented and holds the patent on TI's final test manufacturing process to ensure test quality, and he was the first to implement multisite testing on TI's high-pin-count digital signal processing (DSP) and micro-controller unit (MCU) products.

The Internet of Things (IoT) is an expanding world of Smart applications for anything and everything. Smart homes, smart cars, smart businesses and more, the one thing they all have in common is that manufacturing and testing them has to be equally as smart, and that Time to Market (TTM) is more critical than ever. This session's presentations focus on solutions that address the specific business and technology challenges of IoT. Mike Frazier of Xcerra will discuss how the IoT will change back-end processing. Robert Howell from Exatron will present an overview of perfect serialization solutions for high-volume IoT. Anthony Lum of Advantest will present how to address the need for rapid TTM of IoT devices that are profiled as high mix and low- to moderate- volume. If it's not one thing it's another.

Material Matters
Advanced Materials
& Manufacturing
Advanced products call for advanced materials as well as advanced manufacturing processes. In this session, we look at several aspects of each. Makota Kondo of Omron Corporation explores electroforming technology for the manufacture of probe pins with narrow pitch, which require cost-effective micro-fabrication and accuracy beyond conventional manufacturing methods. Craig Green of Carbice Nanotechnologies discusses the merits of carbon nanotube polymer composites as high-performance thermal interface materials for test and burn-in applications, where low thermal resistance is required combined with high thermo-mechanical cycles. Markku Jamsa from Aspocomp Group discusses the functional requirements and solutions for complex printed circuit boards (PCBs) for test applications. And Don Thompson of R&D Altanova presents on the challenges of PCB test fixtures and sockets for mmWave applications. The materials and processes are advanced, of course, and we think you'll find it very informative.

Stimulating Simulating
Simulation
Simulations help us predict and design for expected conditions. But "information out" is only as good as "information in" and assumptions made. Mike Gedeon of Materion understands that, although finite element analysis (FEA) is a good tool, the real trick to making it work is to understand the modeling process. Although you can always get an answer from any simulation, and especially ones with pretty pictures, it may not always be a correct answer. Mike provides some insights into what to look out for. Gert Hohenwarter from GateWave Northern discusses optimizing the PCB-to-socket-to-DUT (device under test) interface, with tips on specific aspects to address for real-world conditions. Carol McCuen at R&D Altanova suggests that we characterize only the high-speed interconnect performance. This session promises to be stimulating, but perhaps we should run a simulation just to be sure.
