Title: Manufacture of semiconductor package
Inventor: OKAMOTO YOSHIKI
IPC: H01L21/60
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent manufacturing defects and to reduce the number of manufacturing steps. SOLUTION: A notch 40a is formed in advance at the portion of an Ag soldering plate 40 corresponding to the portion substantially midway between pads 1, so that when the step of melting the plate 40 is started the plate 40 is separated almost uniformly at the portion substantially midway between the pads 1, and the molten Ag solder agglomerates almost uniformly over the pads 1. As a result, the meniscus of one separated part of the Ag soldering after cooling is at substantially the same level as that of the other. Therefore, the pads 1 can be connected to a lead frame 30 strongly, and thus manufacturing defects such as the reduction in adhesive strength between the pads 1 and the lead frame 30, and the peeling of the lead frame 30 off a package body 10 made of alumina can be prevented. Furthermore, the plate 40 can be easily arranged between the pads 1 and the led frame 30, and thus the number of manufacturing steps can be reduced.
