The Reliability data presented here were collected during IXYS IC Division product qualification. The purpose of this qualification was to verify the IXYS IC Division Quality and Reliability requirements as outlined in IXYS IC Division internal specifications. The 100V Trench Gate MOSFET is manufactured by IXYS of Milipitas, CA and sample devices LCA701/LCA710/LCA715/CPC1906Y were assembled at ATEC in the Philippines and CPC1709J was assembled at PSI Technologies. Reliability Tests: Table 1 below provides the qualification tests that were performed. The stress tests and sample size are chosen based on the IXYS Integrated Circuits Division internal specification and with the approval of the product development team and quality assurance.

The devices chosen for the qualification were from standard material manufactured through normal production test flow and electrically tested to datasheet limits prior to stressing. Then reliability stresses were conducted and electrically tested to datasheet limit at each interval and final readpoints.

Using the HTRB data, FITs were calculated based on the Acceleration Factor (AF) and equivalent device hours at 0.7eV of activation energy for 125°C test temperature and 40°C use temperatures. The calculated FITs from the reliability stress came out to be 7.66 for HTRB. Table 3: Product IXYS Low Voltage Trench FIT Rate Summary Qual# Stress Product/Kit # of # of Hours Act. Acc.
