Title: Manufacture of semiconductor device
Inventor: YOSAKO TOSHIHIRO
IPC: H01L21/027
Filed: 1987-07-22
Abstract: PURPOSE:To prevent generation of a protruded piece of titanium platinum in patterning process by removing titanium platinum film along with resist film and by forming the resist film again on the titanium platinum film excluding the surface of aluminum pad electrode. CONSTITUTION:A resist film 5 is patterning-formed at the part which does not form a gold bump and then arsenic ions are injected into the entire face of substrate to harden the resist film 5 from the surface halfway. Since the hardened resist film 5' is not developed so much, a bite part 6 is generated between itself and the lower resist film 5 to form an overhang 7. Then, a titanium platinum film 8 is sputtered. If the resist film 5 and 5' are removed, the titanium platinum film 8 is formed so that it widely covers an aluminum pad electrode 2 without forming a protruded piece. Thus, by coating a resist film 9 and by providing gold plating with an aluminum film 4 for electrode as an electrode, a gold bump 10 in a specified configuration is formed only on the aluminum pad electrode.
