Abstract
A packaged microchip has a stress sensitive microchip having a microchip coefficient of thermal expansion, a package having a package coefficient of thermal expansion, and an isolator having an isolator coefficient of thermal expansion. The isolator is connected between the stress sensitive microchip and the package. The microchip coefficient of thermal expansion illustratively is closer to the isolator coefficient of thermal expansion than it is to the package coefficient of thermal expansion.
