Title: Collimator for semiconductor manufacturing apparatus
Inventor: YAMAGUCHI NOBUHIRO
IPC: H01L21/203
Filed: 1995-02-17
Abstract: PURPOSE: To obtain a collimator which increases coverage at the bottom part of a connecting hole in a semiconductor chip, which restrains a drop in a film formation speed and which enhances productivity. CONSTITUTION: A collimator is constituted of two collimator plates 1, 2 having many through holes 4, in the same diameter, through which sputtering particles are passed and of three spacers 3 which support the collimator plates 1, 2 at a prescribed interval. The sputtering particles which impinge obliquely from the side of the collimator plate 1 are stopped by the face on the side opposite to a wafer of the collimator plate 2, they are stuck to the part, and clogging hardly occurs. Consequently, since the coverage of the bottom part of a connecting hole is increased, the film formation speed is not lowered even when the aspect ratio of the collimator is made large, and dust particles are produced little. Then, since the cycle of the replacement of the collimator can be made long, the operating ratio of the collimator is enhanced.

Title: Page printer of electrophotographic system
Inventor: ODAJIMA KENTA
IPC: B41J21/00
Filed: 1990-03-06
Abstract: PURPOSE:To correct the shift of a printing position by a method wherein a displacement amount of paper at right angles to a paper feed direction is detected, and an output timing of an image signal is shifted. CONSTITUTION:A position detector 2 is disposed just after a paper suction part of a feed part 1 to detect a displacement amount of paper at right angles to a feed direction. An image signal control part 3 stores a displacement amount signal issued from the position detector 2 and outputs an address signal and a read signal to a page memory 7 so that the output of an image signal can be delayed by a time corresponding to the displacement amount from a synchronizing position of a horizontally synchronizing signal issued from a control part 4. In the page memory 7, image data for one page are stored. The page memory 7 outputs the image signal to a parallel/ serial converter 8 from an address assigned by the address signal from the image signal control part 3 at the ON timing of the read signal. The parallel/serial converter 8 converts this image signal to a serial signal. In a laser scanning part 5, the signal is converted to the ON/OFF of a laser beam. A drum 10 of an image forming part 6 is repeatedly scanned in a horizontal direction using a rotating mirror 9, whereby an image for one page is formed on the drum 10. In this manner, the shift of a printing position is corrected.
