Simcenter Semiconductor die attach and thermal testing process example

Continuous improvements in quality and reduction in early life failures are key goals for semiconductor manufacturers and their customers. Applications most sensitive include vehicle electrification, server, military and defense and consumer goods.

Historically, semiconductor companies would deploy early life failure reduction efforts with electrical tests or geospatial techniques to reject or test out potential failures. Burn-in and predictive test techniques like part average testing have been around for a long time. Additionally, other geospatial methods such as visual defect screening and algorithmic yield clustering looking for abnormal patterns are used to predict early life failures.

Importance of thermal testing in semiconductor design

In today’s quest for zero defects and better sustainability, companies must reduce manufacturing errors and variability. Inline thermal resistance measurements add another road to quality for semiconductor companies. Thermal transient testing can measure semiconductor junction temperature responses to short pulses and provide insights to potential manufacturing defects. The technology can reveal inconsistencies in the heat conduction path, quantify their effect on thermal resistance and highlight their location. Problems such as thermal interface material (TIM1) or die attach voids or delamination can be found in a fraction of seconds, but problems outside of the package, such as TIM2 quality can also be measured with short pulses.

Watch this webinar to learn how to use thermal transient testing to measure temperature changes in semiconductor packaging and identify potential manufacturing defects.
