Title: Electron beam exposure system
Inventor: MIYAKE AKIRA
IPC: H01L21/027
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To enhance the productivity by performing subscanning while synchronizing the operation of an axis shift with that of an axis deflector and synchronizing the partially limited main scanning operation with that of a wafer stage. SOLUTION: Operation of an aperture stage 39, axis shift coils 42, 43 and axis deflectors 44, 45 are synchronized and main scanning is carried out in the X direction on the exposing regions of a UV-mask 6 and a wafer 1000 limited partially by an a region limiting aperture 37. Furthermore, the main scanning operation is synchronized with the operation of a mask stage 14 and a wafer stage 13 and the UV-mask 6 and the wafer 1000 are shifted stepwise in the Y direction thus subscanning the exposing regions. An operation circuit 46 detects the shifted positions of the mask stage 14 and the wafer stage 13 directly through a length measuring unit 48 and feeds back the detection results thus controlling the subscanning positions of the UV-mask 6 and the wafer 1000 accurately.  Since mechanical operation is not required in the main scanning, the wafer can be exposed over a wide range of the mask at high speed.

Title: Target for magnetron sputtering
Inventor: MISHIMA TERUSHI
IPC: C23C14/34
Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To prevent the sticking and deposition of sputtered products even in the case of high output sputtering and to prevent the generation of coarse particles by subjecting the nonerosion parts in a target face to mirror polishing. SOLUTION: The nonerosion parts at the center and periphery of a target sputtered face are finished into mirror faces having 0.01 to 0.09μm surface roughness Ra (where Ra denotes the center line average roughness). Preferably, the whole body of the sputtered face contg. the nonerosion parts is subjected to mirror polishing into 0.1 to 0.09μm surface roughness Ra. Thus, the unstabilization of sputtering at the time of the start of film formation is prevented, and on the other hand, the sticking and deposition of the sputtered products to the nonerosion parts can be evaded. Moreover, the sputtered face side of a backing plate supporting the target is preferably subjected to mirror finishing as well into roughness similar to that of the sputtered face to remove a factor in the causation of coarse particles from the above part.
