Title: Manufacture of semiconductor device
Inventor: EMATA KOJI
IPC: H01L21/60
Filed: 1985-04-19
Abstract: PURPOSE:To prevent erosion of Al in pad parts and to enhance a bonding strength by performing wire bonding in pad parts by effecting wire bonding after decomposing the organic matter deposited on a surface of a pellet into a gas to remove it. CONSTITUTION:A pellet 3 is bonded to an island part 1 by use of an Ag paste die bonding agent 4 and the surface of the pellet 3 including a pad part is irradiated with ultraviolet rays from an ultraviolet ray irradiation device 5 in the air. By this irradiation with ultraviolet rays, the organic matter which was generated from the Ag paste die bonding agent 4 at bonding the pellet using the Ag paste die bonding agent 4 and was deposited on a surface of the pellet 3 is decomposed and vaporized and further it is separated from the surface of pellet 3. The organic matter deposited on the surface of pellet 3 is thus removed so that the Al erosion reaction in the pad part due to the organic matter does not occur and the Al erosion in the pad part is prevented, thereby manufacturing the high-reliability semiconductor device.
