  • Method of mounting semiconductor chip for producing semiconductor device and a chip-supporting member used therein
    Patent number: 4475007
    Abstract: A method for mounting a semiconductor chip to a supporting member in producing an integrated circuit, and a semiconductor chip supporting member used in this method, wherein the chip-mounting member having a chip-mounting surface with waved peripheral edge pattern is prepared, and a semiconductor chip is mounted onto this chip-mounting surface via a solder preform, and then the resulting assembly is subjected to a heat treatment to melt this solder. Whereupon, even when the semiconductor chip is placed at an eccentric position deviating from the central position of the mounting surface, it is pulled back toward substantially the required central position by virtue of the surface tension of the molten solder.
