Filed: 1999-10-14
Abstract: PROBLEM TO BE SOLVED: To realize micronization of a pattern, while preventing deterioration of precision due to the aberration of a pattern. SOLUTION: In a process for manufacturing a photomask, a mask pattern 5 is divided into two in the scanning direction of a scanner, and a first divided pattern part 10, constituted of a Levenson-type phase shift mask pattern, is formed in one divided region, and a second divided pattern part 20, constituted of an auxiliary pattern type phase shift mask pattern, is formed in the other divided region so that a photomask 1 can be manufactured. In a first exposure process, the first divided pattern part 10 is exposed to a resist on a wafer. In a second exposure process, the second divided pattern part 20 is double exposed to the exposed region exposed in the first exposing process. Thus, deterioration of aberration with the transfer, by a scanner can be prevented. Also, a fine pattern can be realized by using both the Levenson-type and the auxiliary pattern type.

IPC: G03B17/24
Filed: 1993-11-24
Abstract: PURPOSE:To imprint plural optical marks being trimming information at an accurate position on fed photographic film by a single light emitting element and to optionally set the attaching position of a heating element. CONSTITUTION:Every time photographing for one frame is finished, the trimming information of the frame is stored in a RAM for every frame. When photographing is finished, the photographic film 5 is started to be rewound. The trimming information is read out of the RAM, and two optical marks M1 and M2 are imprinted under the frame designated and exposed so that its size may be a panoramic size. At the time of imprinting, the number of pulses synchronized with the rotating cycle of a feeding motor is counted from the point of time when perforation 5D is detected by a photosensor 38. In the case of counting the number of pulses obtained while the film 5 is fed by a distance D1, an LED 40 emits light and the optical mark M1 is imprinted at a specified position. Furthermore, the number of pulses obtained while the film 5 is fed by a distance D2 is counted, and the LED 40 emits the light again.

Title: Formation of insulating film
Inventor: ARAKAWA TOMIYUKI
IPC: H01L21/316
Filed: 1989-11-10
Abstract: PURPOSE:To form an insulating film that is superior in film quality by forming the insulating film which has specific film thickness at a base after performing heat treatment in an atmosphere of an oxidizing gas and after that, in a state that a certain heat treatment temperature is maintained, by performing heat treatment continuously in an atmosphere of an inactive gas. CONSTITUTION:An oxidizing gas, e.g. an oxygen gas is supplied in a reaction furnace 10 in order to form an insulating film having a film thickness of less than about 100Angstrom  on a substrate 18 by performing heat treatment in an atmo sphere of the oxidizing gas and an oxide film is formed on the surface of the substrate after heating the substrate 18 by giving heat treatment to a heating part 16. Then, an inactive gas, e.g. an Ar gas is supplied in the reaction furnace 10 in a state that a certain heat treatment temperature in the case of forming the oxide film is maintained for the substrate 18 on which the oxide film is formed and heat treatment is carried out for hours desired. As a result, after insulating films are formed, the insulating films which are not bonded yet and have weak bonding are lessened by heat treatment in an atmosphere of the inactive gas. Each insulating film which has the film thickness of less than about 100Angstrom  and is superior in film quality is thus formed.

Title: Speed detector
Inventor: MIYATA HAJIME
IPC: G11B15/54
Filed: 1985-12-26
Abstract: PURPOSE:To reduce the size of a detector by uniting a roller and a slit plate, and also changing the direction of light propagation by using a prism. CONSTITUTION:A slit plate 3a is adhered to the reverse surface of a light- transmissive roller 1 which has a rotating shaft 2 and rotates in one body. A slit plate 3b is fixed to a housing opposite the slit plate 3a. Light emitted by an LED 5 is changed in propagation direction and reaches a phototransistor 4 through a path 8. The slit plate 3a, however, rotates integrally with the roller 1, so the rotational displacement of the roller 1 is detected as the output of the electric signal of the phototransistor 4 by the slit plates 3a and 3b from the transmission and nontransmission of the light. Thus, the roller 1 and slit plate 3a are united to shorten the rotating shaft, and prisms 6a and 6b are used to increase the degree of freedom of the fitting positions of the LED 5 and phototransistor, thereby reducing the size of the detector.

Abstract: PROBLEM TO BE SOLVED: To provide a focal-plane shutter for a camera which is constituted so that the traveling start position of a first blade group and a second blade group can be stably obtained before the traveling for exposure and which is advantageous in terms of a cost. SOLUTION: By a spring part If formed on a bottom board member 1 made of synthetic resin by a unified molding method, the projection part 3a of an arm 3 is pressed in a shutter charge state.

Just after the first blade group is started, the projection part 6a of an arm 6 is pressed by the spring part If and the initial position of the second blade group is decided in the same way as the first blade group. Therefore, the respective blade groups can be always made to travel for the exposure from the identical position.

IPC: H04H40/36
Filed: 1992-11-04
Abstract: PURPOSE:To simplify the structure and enable high-speed processing while the successive start timing being independent of the presence or absence of data error by correcting errors a batch in prior to error detection. CONSTITUTION:An error correction section 4 constructed by hardware reads data written in a memory 3a, making an error correction in the horizontal direction to write data in a memory 3b. A CRC circuit 5 reads out the data to detect error. If the data is normal, error corrected data are sent to a memory 7a. If the data is abnormal, uncorrected data are sent to the memory 7a. Then, a CPU 6 reads out data from the memory 7a in the vertical direction, gives them to an error correction section 8 to correct errors. If the number of errors is less than N bit, the corrected data are written in the memory 7b. If it exceeds the N bit, the data before correction are written in the memory 7b. In short, the error correction in the horizontal or vertical direction can be made constant for each unit regardless of the presence or absence of data error, and the start timing of the next stage processing can be stabilized.
