Abstract
In semiconductor device fabrication, warping of the support pins must be prevented so that the semiconductor element can be properly positioned during the wire-bonding and resin-sealing processes. The invention provides a process in which a V-shaped groove 33, for example, is formed in the mounting pad 31 and the support pins 32, imparting rigidity to the support pins 32.
