SEMICONDUCTOR DEVICE

摘要

PURPOSE:To mount and fix a semiconductor device including an integrated circuit region layer without providing an insulating layer on a wiring frame. CONSTITUTION:There are provided a predetermined conductivity type integrated circuit region layer 21, and a support region layer 21, and a support region layer 22 for supporting the integrated circuit region layer 21. The support region layer 22 has a conductivity type complemetary to the integrated circuit region layer 22 The integrated circuit region layer 21 is back-biassed by a bias circuit 29.
