High Voltage Testing Races Ahead


Voltage requirements are increasing, especially for the EV market. Even devices that might be considered relatively low voltage, such as display drivers, are now pushing past established baselines. While working with high voltages is nothing new — many engineers can recall yellow caution tape in their workplaces — the sheer number and variety of new requirements have made testing at high... » read more

More Manufacturing Issues, More Testing


Douglas Lefever, CEO of Advantest America, sat down with Semiconductor Engineering to talk about changes in test, the impact of advanced packaging, and business changes that are happening across the flow. What follows are excerpts of that discussion. SE: What are the big changes ahead in test? Lefever: It's less about inflection points and more like moving from algebra to calculus in the ... » read more

Failure Prediction Is Vital for Packaging Technology


A while back, I wrote a post on what I call the “10 Commandments of Packaging” – my list of the key things to bear in mind with respect to developing new packaging solutions. Today, packaging engineers must contend with more variables than ever, from new substrate materials to more types of packages with a greater range of complexity. With that complexity comes new challenges, and I felt ... » read more

The Importance Of Product Burn-In Test


Product burn-in (BI) is an indispensable step in the production test flow to ensure good quality and a properly functioning product for the customer. Amkor takes pride in rating ‘quality delivered to the customer’ as one of the highest corporate virtues. See figure 1. Fig. 1: Defects per Million (DPM) and DPM goal reported over five years. Burned-in integrated circuits (ICs) have a ... » read more

Adaptive Test Gains Ground


Not all devices get tested the same way anymore, and that’s a good thing. Quality, test costs, and yield have motivated product engineers to adopt test processes that fall under the umbrella of adaptive test, which uses test data to modify a subsequent test process. But to execute such techniques requires logistics that support analysis of data, as well as enabling changes to a test based ... » read more

Leveraging Data In Chipmaking


John Kibarian, president and CEO of PDF Solutions, sat down with Semiconductor Engineering to talk about the impact of data analytics on everything from yield and reliability to the inner structure of organizations, how the cloud and edge will work together, and where the big threats are in the future. SE: When did you recognize that data would be so critical to hardware design and manufact... » read more
