Improving Yield, Reliability With Data


Big data techniques for sorting through massive amounts of data to identify aberrations are beginning to find a home in semiconductor manufacturing, fueled by new requirements in safety-critical markets such as automotive as well as the rising price of packaged chips in smartphones. Outlier detection—the process of finding data points outside the normal distribution—isn't a new idea. It ... » read more

The 2017 International Test Conference


Machine learning is a hot topic at many technical conferences this year. It will be true at the upcoming International Test Conference, which opens near the end of this month in Fort Worth, Texas. On Sunday, October 29, there are two tutorials devoted to machine learning. Monday, October 30, will have one tutorial related to the topic. The conference gets fully under way on Halloween, wit... » read more

How To Make Autonomous Vehicles Reliable


The number of unknowns in automotive chips, subsystems and entire vehicles is growing as higher levels of driver assistance are deployed, sparking new concerns and approaches about how to improve reliability of these systems. Advanced Driver Assistance Systems (ADAS) will need to detect objects, animals and people, and they will be used for parking assistance, night vision and collision avoi... » read more

Module Testing Adds New Challenges


System-in-package (SiP) and other advanced packaging technologies are putting more components together in tighter spaces than previously seen. Often these packages are contained in a module, which is something more than a chip package and a great deal smaller than most printed circuit boards. Testing these modules often requires system-level test. These modules typically will be inserted int... » read more

Massively Parallel System-Level Testing


Decades of advances in the semiconductor industry continue to drive an insatiable consumer demand for smaller, more powerful, more ubiquitous devices – whether in our cars, on our countertops or around our wrists. To meet this demand now and into the future, the fabrication of increasingly complex semiconductor systems for an incredible spectrum of applications must scale accordingly. Additio... » read more

The Future of Testing


In our previous test blog posts, we looked at the history of automated test equipment for semiconductors and for printed circuit boards. This month, we look ahead to the test technologies that are emerging. The chip ATE field has essentially boiled down to Advantest, Teradyne, and Xcerra (LTX-Credence), while the board test market is dominated by Teradyne and Keysight Technologies (formerly ... » read more
