Abstract
A surface mount package for use with large area silicon device. The package uses a pressed ceramic frame and solid metal pads which are closely matched for coefficient of thermal expansion (CTE) to each other and to the silicon die. The package is specifically designed for large area die (greater than 0.0625 inches squared) and for high temperature eutectic alloy bonding. All materials of the package are CTE matched to each other and to silicon within 10%.
