Title: Mounting method of semiconductor device
Inventor: KIMURA TOSHIHIRO
IPC: H01L23/12
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To form a semiconductor device, wherein mounting height is readily made low and constant and reliability is high by providing a back-surface resin covering the opposite surface of an electrode forming surface of the semiconductor element. SOLUTION: A back surface of a silicon wafer is ground by using a back grinder and the like, and the specified thickness is set. Thus, back-surface resin 6 having the specified thickness is provided. A bump 4 of a semiconductor element 1 is connected to a wiring 3 formed on a substrate 2. Therefore, the thickness of the semiconductor element 1 can be made small. It is easy to make the mounting height low and constant. Furthermore, since resin needs to be applied only on the upper surface and the side surface of the semiconductor element 1, encapsulating resin 5 is applied readily on the semiconductor element uniformly. Therefore, dispersion is not generated in moisture resistance. Thus, the highly reliable semiconductor device can be formed.
