IPC: H01L21/603
Filed: 1993-12-24
Abstract: PURPOSE:To improve the strength of bond between a board having a wiring pattern formed thereon and a device having solder bumps formed thereon through thermocompression bonding, by microminiaturizing the structure of the solder bumps. CONSTITUTION:Cu 2 and solder are continuously plated on a semiconductor substrate 1, and the solder is melted by YAG laser light.
