Title: Exposure method
Inventor: YAMASHITA KAZUHIRO
IPC: G03F1/76
Filed: 1990-11-30
Abstract: PURPOSE:To simply increase resolution limit higher than the conventional limit, by dividing a periodically arranged mask pattern into two mask patterns, and projecting in order the divided patterns on the same substrate by using a demagnification projection aligner. CONSTITUTION:A periodically arranged mask pattern 3 is divided into patterns 1 and 2 which have a period two times longer. A first mask pattern having a first pattern is projected on photo resist on a semiconductor substrate with a demagnification projection aligner. The first mask is exchanged for a second mask having a second pattern, which is again projected on the same substrate. After exposure, the semiconductor substrate is developed by using developing solution like NMD-3. By this method, the resolution limit can be increased higher than the conventional value, while the same exposure light wavelength and NA as the conventional ones are used. Hence the level of integration of a semiconductor integrated circuit can be improved.

Filed: 1989-12-27
Abstract: PURPOSE:To detect the position of an object with good accuracy by comparing the virtual receiving amount of light and the adjusted receiving amount of light from each photodetector with a reference level to determine whether or not the light is shut off to the object. CONSTITUTION:The position of an object between an array 11 of photoemitting elements and an array 12 of photodetecting elements is detected. Each receiving amount of light by the array 12 is input to a first operation controlling means 13 while the variation of the receiving amount of light without the object is adjusted. At this time, at least the virtual middle position between two adjacent photodetecting elements and the virtual amount of received light are obtained by the adjusted amount of received light from the photodetecting element and the adjusted amount of received light from the adjacent photodetecting element by calculating the arithmetic means. The virtual middle position and virtual amount of received light are sequentially output along with each adjusted receiving amount to a comparing means 14 to be compared with a reference level. If the result of the comparison shows the fact that the light is shut off, the corresponding photodetecting element and virtual position are output and stored as data of a light shielding position from the means 13 into a memory means 15. A second operation controlling means 16 operates the position of the object from the data of the light shielding position in the means 15.

Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce the manipulating force by forming a small air cylinder in a piston rod of an air cylinder, by setting the pressure in the small air cylinder to a value which is different from a pressure in the air cylinder. SOLUTION: When air is fed into air sources 14, 15, air flows into them through a valve seat, and accordingly, a diaphragm piston 2 is pushed downward while a casing 2 is pushed upward. Further, the air flowing through the valve seat 11 flows through a flexible pipe line 16 and applies a thrust force to a piston rod 4 of an air cylinder 5. Further, air having a pressure adjusted by a pressure reducing valve 13 with a relief function flows into a small cylinder 6 formed in a piston rod 4 so as to also apply a thrust force to the piston rod 4. In this condition, if air is continuously fed through the valve seat 11, the pressure is increased, and when it balances with a load 7 and the gravitational force of the casing 2, the valve seat 11 is closed. In this condition, the total thrust force exerted to the piston rod 4 is balanced with the gravitational force of all movable parts including the piston rod 4.
