Abstract

PURPOSE: To simplify construction and obtain sufficient close contact, by providing a depressed part and a projected part respectively on the surfaces of contact of an internal buffer electrode and a copper cover placed on a semiconductor junction base constituting a planar type semiconductor device.
CONSTITUTION: Junction support 6 is fixed on a base having copper base 4 via solder layer 5. On top of this is mounted semiconductor junction base 8. Next, on top of this is placed internal buffer electrode 2, and the junction surface of electrode 2 and base 8 is protected by stabilizer 13. A base having copper cover 1 is mounted on electrode 2 under pressure. The end parts of copper cover 1 and copper base 4 are sealed with ceramic seal 7, and thereby a planar semiconductor device is formed. In this structure, projected part 9 is provided on the lower surface of copper cover 1, and depressed part 10 on internal buffer electrode 2. By this, sufficient close contact can be obtained without using an ordinary fixing device.
