IPC: H01L21/3065
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To reduce the local variation of etching which occurs when a dry etching device is used by providing an electrode for mounting a wafer to be etched in a chamber and providing a plurality of exhaust ports around the electrode, and then, individually controlling the exhausting quantities of the ports in accordance the etching rate in the surface of the wafer. SOLUTION: A sample wafer 4 is etched by setting the numerical apertures of exhaust ports 6 provided at regular intervals around a lower electrode 5 to certain conditions. When the etching amount in the surface of the wafer 4 fluctuates, the numerical apertures of the ports 6 near the part of the wafer where the etching rate is lower are reduced so that an etching gas can stay longer on the wafer and the etching rate at the part is raised. When the etching rate at a certain part is high, on the contrary, the numerical aperture of the ports 6 near the part are lowered and the etching rate at the part is lowered. Therefore, the local variation of etching can be reduced by making the plasma density uniform on the wafer.

Title: Width direction alignment of belt-shaped film
Inventor: UEMURA KAZUTAKA
IPC: B41J17/36
Filed: 1987-06-16
Abstract: PURPOSE:To achieve accurate alignment, by stopping the movement of a film when a boundary line of a width direction position detection mark on the film is aligned with a detection position of an optical-type sensor from a predetermined side, in a transfer printer. CONSTITUTION:A transfer film X supplied from a film payout part 12 is intermittently fed between a male mold 2 provided with a molten-resin injection nozzle 5 and a female mold 3 by a film-supplying device 10, and is simultaneously molded and transfer printed. The position of the film X in the width direction is corrected by transversely moving the film X by a movable frame 37 through driving a feed screw 37 by a motor when a mark Z provided at a side end part of the film X is deviated from a detecting position 62a of an optic sensor 62. When a boundary line Z1 of the mark Z is aligned with the detecting position 62a of the sensor 62 from a predetermined side, the movement by the feed screw 37 is stopped. Thus, constantly accurate alignment with a predetermined position can be performed, irrespective of the hysteresis of the sensor, and simultaneous molding and transfer printing or the like can be accurately performed.
