Title: Method and apparatus for photoexcitation dry-etching
Inventor: MOCHIZUKI YASUHIRO
IPC: H01L21/302
Filed: 1987-05-18
Abstract: PURPOSE:To improve the uniformity and reproducibility of etching by a method wherein a sample to be etched is exposed to reactive gas long enough for the reactive gas to reach the silicon boundary of the sample through a natural oxide film, irradiated with light and then photochemical reaction is started. CONSTITUTION:A sample to be etched is exposed to reactive gas beforehand and then ultraviolet rays are applied to accelerate photochemical reaction. In other words, the sample is placed in a reaction vessel 1 and, after the vessel 1 is evacuated, the reactive gas is supplied to the vessel 1. After the oxide film on the surface of the polycrystalline silicon film of the sample is removed by fluoric acid, the sample is washed and dried and then ultraviolet rays from a low voltage mercury lamp 6 are applied to the sample in the air to form a natural oxide film. With this constitution, the masking effect of the natural oxide film in a photoexcitation dry-etching process of silicon can be avoided.

Filed: 1987-05-18
Abstract: PURPOSE:To keep the pattern surface of a mask at a predetermined position by a method wherein a displacement detecting means and a pressure controlling means are provided and a pressure applied to the pattern surface is controlled in accordance with the displacement of the pattern surface. CONSTITUTION:The position displacement of the pattern surface of a mask 10 along the direction vertical to the pattern surface is detected by a displacement detecting means 110 and a pressure applied to the pattern surface is so controlled as to make the displacement zero by a pressure controlling means 130. In other words, the displacement detector 110 detects the displacement of a mask membrane 20 and outputs a detection signal to a signal processor 120. The signal processor 120 calculates a pressure which deforms the mask membrane 20 in accordance with the deviation of the position of the mask membrane 20 from its initial position and supplies the calculated pressure to the pressure controller 130. The pressure controller 130 controls the pressure in a pressurizing chamber 100 so as to make the pressure equal to the calculated value. With this constitution, the deformation of the pattern surface of the mask at the time of gap setting can be avoided and the time required until the gap becomes stable can be eliminated.

Abstract: PURPOSE:To stabilize the detection of an out-of-focus state by providing a photodetector, which is arranged in a position deviated from the image formation position for the in-focus state and has plural detecting cells, and a means which moves a spot in accordance with the deviation of a storage medium and placing one detecting cell on the optical axis at least. CONSTITUTION:The beam of an out-of-focus state detecting system which is divided by a half mirror 10 is taken out asymmetrically with respect to an optical axis 14 by a light shielding plate 13 and is made incident on a photodetector 16 having light detecting cells 16-1 and 16-2. An area 21 of the detector 16 has not an optical detection sensitivity practically. The light receiving face of the photodetector 16 is deviated from the image formation position in the in-focus state. The position of a center point 21' of the area 21 is deviated from an intersection 14' between the optical axis 14 and the detector 16. A width 21'' is so narrowed that the point 14' is placed on the outside of the area 21. In the out-of-focus state, a spot 22 is deviated upward from the center of the light receiving face and is larger than that in the in-focus state. A reflected beam from an object lens 5 is convergent. In this case, the spot 22 is converged once in a position deviated from the point 21'; and when the out-of-focus degree is increased, it is inverted downward. Thus, the out-of-focus state is detected stably.
