Title: Electrode bond and method of bonding electrode
Inventor: YAMANAKA TAKESHI
IPC: H01L23/48
Filed: 2002-08-05
Abstract: <P>PROBLEM TO BE SOLVED: To provide an electrode bond which has a superior thermal fatigue characteristics and has high durability.  <P>SOLUTION: The electrode bond comprises a base constituted of a first electrode or a semiconductor element, a second electrode bonded to the base, and a solder layer for electrically connecting the base and the second electrode. The second electrode has a recessed section which is formed in part of a surface in contact with the base and is to be filled with the solder layer, and a buffer section which is a remaining part of the surface and surrounds the recessed section and is fixed to the base. By forming the recessed section in part of the surface of the second electrode which is in contact with the base and forming the solder layer in the recessed section, the periphery of the solder layer is restrained by the buffer section of the second electrode. The buffer section is the remaining part of the surface left behind the part in contact with the base, and has such a shape as to surround the recessed section, and hence plastic deformation at ends of the solder layer due to thermal stress applied to the solder layer can be suppressed by the buffer section. Consequently, the occurrence of lifting/cracks of the solder layers at the joint can be suppressed, resulting in increasing the durability of the joint.  <P>COPYRIGHT: (C)2004,JPO
