Title: Equipment and method for film formation
Inventor: HOSHINO AKIRA
IPC: H01L21/768
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To obtain a film forming equipment which improves productivity and prevent the deterioration of manufacturing yield by enabling formation of each film which differs in film forming regions, in the formation of a barrier metal film composed of a laminated film. SOLUTION: In a sputtering equipment, a cylindrical sidewall 4 surrounding the periphery of a stage 5 on which a substrate 3 is mounted is installed. By changing the relative position of the cylindrical sidwall 4 and the substrate 3, a plurality of films are formed. In this case, an incidence region of particles for film formation on the substrate end is controlled. Thereby it is made possible that a laminated film, composed of films different in the film forming region, is formed in the same structured film forming equipment. By applying this equipment to the formation of a titanium and titanium nitride laminated film as a barrier metal film for blanket W growth, film formation can be made such that a titanium film is covered with a titanium nitride film on the substrate end, and the occurrence of film exfoliation at the time of W growth is prevented.
