Semiconductor apparatus of module installing type

摘要

A semiconductor apparatus comprises a heat diffusing plate and a surface installing printed board. A semiconductor device of a high heat generation is installed on the heat diffusing plate. A surface installing package and chip parts are installed on both surfaces of the printed board. A through hole is formed at the center of the printed board so that the semiconductor device is located at the center. The heat diffusing plate on which the semiconductor device has been installed and the surface installing printed board are connected and integrated.
