Title: Method of bonding resin to substrate
Inventor: YAMADA TOMIO
IPC: H01L23/28
Filed: 1985-03-29
Abstract: PURPOSE:To prevent resin from shrinking or expanding due to the temperature cycling thereof, by providing a groove having projections on the inner walls in the direction intersecting with the line connecting a semiconductor pellet and a tightening hole. CONSTITUTION:After sealing with resin, the resin on the side A1 is prevented from moving toward the side A2 due to thermal shrinkage. Even if a little gap is produced between the resin and a heat releasing plate 1 by tightening a bolt, the resin is prevented from moving toward the side A2 by the presence of a groove 7, and the stress applied to the area of a semiconductor pellet 3' due to the expansion or shrinkage of the resin is reduced. Consequently, the semiconductor pellet 3' is effectively prevented from cracking and wires from disconnecting. The groove 7 provides remarkable effect of preventing the resin from moving toward the side A2, particularly because it has projections 8 on the inner walls. These projections 8 also serve for improving the strength in the peeling direction F.
