Title: Bias sputtering device
Inventor: YOKOGAWA TOSHIO
IPC: C23C14/34
Filed: 1986-02-13
Abstract: PURPOSE:To make the film thickness distribution of a deposited film uniform by placing an insulator between a substrate and bias electrode and adjusting the distribution of dielectric losses. CONSTITUTION:A quartz plate or the like 41 which is the same material as the material of a target 5 and the high dielectric loss insulator 42 consisting of an annular plate made of a polyimide resin or alumina are inserted between the rear of the substrate 4 and the front of the bias electrode 3. The thickness of such insulator 42 is selected between about 0.2-0.5mm to adjust the distribution of an etching speed. The film thickness distribution of the thin film to be deposited on the surface of the substrate 4 is improved by such bias sputtering device. Since the surface of the insulator 42 to be exposed to plasma is covered by the same material as the material of the target 5, the contamination of the deposited film by an etching material is prevented.

IPC: B41J2/465
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To decrease the light quantity unevenness occurring in the history phenomenon of an optical modulation element by regulating the drive voltages of an optical modulation element drive circuit in accordance with the measured value of the output light quantity measured by a light quantity sensor when the accumulated time of drive attains a prescribed value. SOLUTION: After a halogen lamp 21 is lighted by a driver 81, the light quantity sensor 72 is moved forward from the initial position on the outside of the scanning region of an optical shutter array. The respective drive voltages are successively impressed from an optical shutter element drive circuit 80 by each of optical shutter chips to turn on the optical shutter chips. The light quantity sensor 72 measures the output light quantity of the optical shutter chips in the on state and captures the same into a CPU 94. The output light quantity captured into the CPU 94 is smaller than the ordinary initial value. The drive voltages of the optical shutter chips are, thereupon, regulated from the difference between the captured output light quantity and the initial value.  Further, the drive time counted by a timer is added and the drive voltage regulation of the optical shutter chips is executed every time the drive time exceeds the specified accumulation time.
