Title: Method for forming bump semiconductor device
Inventor: MOHAN KIRUROSUKAA
IPC: H01L21/60
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To enable forming of a bump without excessively heating a semiconductor device and to increase the reliability of the semiconductor device. SOLUTION: A bump is formed by transferring a bump forming material 16 to an electrode pad of a bump supplying substrate 20 which is provided with the bump forming material 16 in a position corresponding to an electrode pad 38 formed on a semiconductor device. A metal layer 12 is formed on the bump supplying substrate 20. The wettability of the metal layer 12 to the molten material 16 for bump forming is less than the wettability of the molten material 16 to the electrode pad of the molten material for bump. The bump forming material is heated to become molten on the surface of the metal layer 12. The molten material 16 is aligned with the electrode pad 38 of the semiconductor device 30, and the molten is brought into contact with the electrode pad. The molten is transferred from the bump supplying substrate 20 to the electrode pad of the semiconductor 30 to form a bump.
