ABSTRACT:
A semiconductor device including: an insulating substrate including a ceramic substrate having first and second principal surfaces, a first metallic conductor fixed on the first principal surface, and a second metallic conductor fixed on the second principal surface; a semiconductor element disposed on the first metallic conductor on the first principal surface; and a base plate connected to the second metallic conductor on the second principal surface, and on which the insulating substrate being disposed. The second metallic conductor includes a joint area connected to the second principal surface, and a non-joint area formed around the joint area.
