Title: Semiconductor device
Inventor: YAMAZAKI BISHIYUKU
IPC: H01L23/40
Filed: 2001-05-16
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a semiconductor device. SOLUTION: The semiconductor device has a semiconductor chip 1, a support electrode 5 bonded to one end of the chip 1 through a bonding member 3 and a lead electrode 7 bonded to the other end of the chip 1 supported with the support electrode 5 through a bonding member 3. The support electrode 5 has screw threads on the outer wall and is screwed into a heat sink 13 tightly enough to reduce some strain caused in the semiconductor device, compared with the driving and fixing of the support electrode 5 into the heat sink 13 tightly. Thus, the chip 1 can be set in a hole formed into the heat sink 13 to reduce the distance between the chip 1 being a heat source and the heat sink 13, thereby lowering the thermal resistance to radiate heat enough. This improves the reliability of the semiconductor device.
