Latest Patents

One of Soh Ying Seah's latest patents is the "Multiple rate signature test to verify integrated circuit identity." This invention allows for the screening of a batch of integrated circuits (ICs) using test patterns provided in a sequence of test vectors. The process involves fetching the sequence from a memory connected to a tester, where bits from each test vector are utilized to form a test pattern. This pattern is then applied to an input pin of the device under test, allowing for the monitoring of the resulting signal on the output pin of each IC. A unique aspect of this patent is the method of screening slow-speed ICs by treating those that pass both fast and slow pattern tests as failures.

Another significant patent is the "Kill die subroutine at probe for reducing parametric failing devices at package test." This method involves testing semiconductor devices by contacting bond pads on a first die using a probe system. The testing includes various probe tests, such as parametric and continuity tests, and utilizes a kill die subroutine to selectively damage certain dies to generate continuity failures. This innovative approach helps in effectively binning the dies based on their performance.
