Title: Lead frame for semiconductor
Inventor: TAKEMOTO YOSHITAKA
IPC: H01L23/50
Filed: 1987-04-13
Abstract: PURPOSE:To prevent the metal plating for bonding from being brought into contact with lead frames even when the lead frames are superposed thereon by a method wherein the plate thickness of a part, on which the metal plating for bonding is to be conducted, of a semiconductor element placing part and an inner lead is reduced beyond the thickness of the metal plating for bonding. CONSTITUTION:The plate thickness T1 of the semiconductor element placing part 2 and the inner lead 4 located in a plate thickness reduced region 9 is reduced thinner than the plate thickness T2 of the other part in excess of the thickness T3 of the metal plating 8 to be used for bonding, namely, in the thickness of T1<=T2-T3. Then, the metal plating 8 for bonding is conducted on the surface 10 on which plate thickness is reduced. Accordingly, the metal plating 8 for bonding does not protrude in excess of the surface 10. As a result, the metal plating 8 for bonding is prevented from contacting to the adjoining lead frame.
