Title: Connection of wire bonding
Inventor: KATO TOSHIHIRO
IPC: H01L21/60
Filed: 1988-10-24
Abstract: PURPOSE:To set a bonding characteristic to an electrode pad on the side of a second bond at a level identical to that on the side of a first bond and to enhance a life as a whole when a bonded part is left at a high temperature by a method wherein a metal ball is formed in advance in a wedge bonding part in a pellet-pellet bonding operation. CONSTITUTION:An Au ball 7 is formed in advance on an Al electrode pad for a second bond of a second pellet 2. Then, a metal ball is formed again on an Au wire of a bonder; this ball is ball-bonded to one end 8a of a metal thin wire 8 at a first bond of a first pellet; the other end 8b of the Au wire 8 is wedge-bonded and connected to the Au ball 7 which has been formed before at the second bond of the second pellet 2. Thereby, it is possible to relax a mechanical impulsive force during a wedge bonding operation on the side of the second bond; especially regarding a life at the time when a bonded part is left at a high temperature, it is possible to obtain a wire bonding connection of sufficient reliability.
