Title: Sputter deposition apparatus
Inventor: TAKEUCHI KIMIHIKO
IPC: H01L21/203
Filed: 2001-03-05
Abstract: PROBLEM TO BE SOLVED: To provide a sputter deposition apparatus which can form a film accurately on a predetermined region of a substrate. SOLUTION: The sputter deposition apparatus has a metal mask 3 for covering a substrate 10. An insulation film 4 is formed along the verge of opening 31 of the metal mask. Thereby, a raw material sputtered from a target 2 flows through the opening 30 toward the substrate 10, avoiding the verge 31 of the opening of the metal mask 3, because the insulation film 4 on the verge 31 of the opening of the metal mask 3 is charged during sputter film formation. The raw material passing near the verge 31 of the opening flows like an approximately parallel current, and consequently does not creep into a backside 32 of the metal mask 3. Thus, the film 7 is formed only on the predetermined area of the substrate 10 corresponding to the opening 30 of the metal mask 3 in high accuracy.
