IPC: B23K26/00
Filed: 2000-04-28
Abstract: PROBLEM TO BE SOLVED: To increase the yield of a semiconductor device by increasing the reproducibility of a wafer bonding. SOLUTION: In a semiconductor wafer 11, having a multilayered structure which is made by laminating a plurality of semiconductor wafers, wholes 14 which reach a bonding interface are formed at intervals of the chip size.
