Title: Semiconductor device having bump
Inventor: OKUMURA KATSUYA
IPC: H01L21/60
Filed: 1979-10-03
Abstract: PURPOSE:To prevent the fall of the mechanical strength of the bump of a semiconductor device as a result of the Al-Au alloying reaction by providing an Au bump on a conductive layer exposed in the opening in an insulative film through a barrier metal layer and a metal conductive layer different from said conductive layer. CONSTITUTION:On an Si substrate 1, an Al wiring 2 is formed, which is coated with a PSG film 3. Then an opening 5 is made in the film 3 by using as a mask a resist film 4 having an opening portion. After the whole surface is coated with a Pt layer 6, the film 4 is removed to lift off the layer 6 on the film 4 so that the layer 6 only in the opening 5 is left to form a barrier Pt layer 6'. The whole surface is coated with a Cr thin film 7 and Au thin film 8 successively, on which a resist film 9 in which a bump-forming portion has been opened is provided, and then Au bump 10 is formed. Thus, interposing the barrier Pt layer 6' between the Al wiring 2 and the Cr thin film 7, Au thin film 8 and Au bump 10 can prevent the fall of the mechanical strength of the bump 10 as a result of the Al-Au alloying reaction.
