Title: Lead frame structure
Inventor: HARA SOTOMITSU
IPC: H01L21/60
Filed: 1980-10-22
Abstract: PURPOSE:To improve reliability on wire bonding by a method wherein a pellet fixing surface and a wire connecting surface in a lead frame are arranged to have a reverse displacement individually reffering to a reference level, and by a reduced dip of wires, contact between them is prevented. CONSTITUTION:A pellet 2 is attached with paste 3 onto a tab region 4 on a lead frame 1, a lead wire 6 is connected to a wire 5 by bonding, and continuously a resin mold process is performed. A structure of a lead frame 1 is so taken and formed by press that a pellet fixing surface A may be lower than a reference level R and a bonding surface B may be higher than the reference level R, having a displacement along the reverse direction individually. By this constitution difference of height between bonding regions can be reduced, and thus reduction of wire length and a dip can be attained. Consequently contact between wires when molded and contact between the wire and the pellet is effectively prevented.
