Summary:
This talk will summarize research done on the physical, mechanical, thermal, and electrical properties of various types of Polyimide and Poly-Benz-Oxazole (PBO) materials after curing under different process parameters, under atmospheric and vacuum process conditions. At both conventional and low temperatures, the vacuum process resulted in higher thermal stability, lower outgassing, and better thermal properties. The vacuum cure also showed better dielectric strength as well as lower dissipation factor. The assumption that curing under vacuum reduces the amount of volatile and volatilizable material remaining in the film appears to be consistent with these results.
Bio: Kia Karim an IEEE Sr. Member, is currently Sr. Vice President and Chief Technology Officer (CTO) at YES (Yield Engineering Systems, Inc.), a leading supplier of semiconductor equipment for backend Advanced Packaging processes. Dr. Karim was previously Vice President of Business Development and Technology at AIXTRON/Genus (acquisitions) where he worked for over 15 years. Dr. Karim also held senior management positions at Applied Materials and Novellus, after starting his career at Sharp Microelectronics in 1994.
