Title: Dry etching method for semiconductor device and manufacturing device thereof
Inventor: SHIN KYUN-SU
IPC: H01L21/768
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To prevent the corrosion of the photoresist film pattern in an etching region by making the specified parts of the photoresist film patterns on both sides of etching part to remain without etching, forming a polymer thereon and maintaining the line width of the etching part. SOLUTION: When an oxide film 22 is etched for 5 minutes by using pressure, power and etching gas and using delay conditions, a photoresist film pattern 24 is also etched to the some degree. However, the respective photoresist film pattern 24 on both sides of a contact hole 26 remains at a non-etching photoresist film pattern 27 in the shape of a mountain different from the other part. Even if the etching time is increased, the pattern 24 is not etched. The quantity of polymer 28 formed on the pattern 27 is increased. The polymer 28 prevents the corrosion of the patterns 27 on both sides of the contact hole 26. When the etching time is increased, the polymer is formed at the input side of the contact hole 26. A line width a2 is maintained. A line width b1 at the lower part of the line width a2 is formed relatively small.

Title: Drive control of stepping motor
Inventor: KIMURA MAKOTO
IPC: H02P8/00
Filed: 1995-07-06
Abstract: PROBLEM TO BE SOLVED: To reduce the number of times of generation of impact sound at initialization by additionally attempting the step drive as much as the number of times of excitation patterns of one cycle from the initial position adjacent to the stopper. SOLUTION: The number of excitation patterns 4 of one cycle is added to the reset position +10 of the initial position and the target step position 14 is set. The step drive is executed as much as 8 steps obtained by subtracting the control step position +6 as large as memory backup from the target step position +14. Finally, switching is made to the excitation pattern A'-B' of the target step position +14. Thereby, the interval from stopper S0 of the step position +10 before one cycle having the excitation pattern A'-B' which is the same as that of the step position +14 is smaller than that the targe step position +14. Therefore, the rotor is step-driven toward the step position +10 as the reset position of the initial position and thereby it always collides once with the stopper S0 .

Abstract: PURPOSE:To control a development contrast voltage so that cyclical electrification-irregularity on a photosensitive drum surface based on the AC bias of an electrostatic charger is compensated. CONSTITUTION:The surface of the photosensitive drum 5 is uniformly charged by applying a DC bias and an AC bias to a charging roller 1 by means of a power source 6. An electrostatic latent image is formed by an exposure optical system 2, and the electrostatic latent image is developed by applying a development bias to a developing roller 3 by means of a power source 9 and generating a development contrast voltage between the photosensitive drum 5 and the roller 3. Based on the cycle of the AC bias of the charging roller 1, the charging of the surface of the photosensitive drum 5 becomes irregular. By connecting an attenuator 7, a phase shifter 8, and an addition circuit 10 to the power source 6, the AC bias is attenuated, the phase is properly shifted, and overlapped on the power source 9 to be applied to the developing roller 3. Thus, the development contrast voltage which compensates the charging irregularities is generated.
