Abstract: PROBLEM TO BE SOLVED: To provide the prism which can obtain by itself all of a function of shaping a laser light, a function of correcting power variation and optical-axis tilt variation of projection light even if the laser light varies in wavelength, and a function of putting laser lights emitted from two semiconductor laser light sources differing in wavelength together into the same optical path. SOLUTION: The prism 5 has 1st optical paths L1 to L6 and 2nd optical paths L7 to L11 inside and also has optical constants set so that at least one of those two optical paths has function of shaping a laser light and a function of correcting power variation of a beam shaping prism and optical axis tilt variation of a projection light even if the wavelength varies; and those functions are obtained by a single-body prism 5 formed by laminating 1st, 2nd, and 3rd prisms 5A, 5B, and 5C of different refracting index materials together in one body, so when the prism is mounted on an optical pickup device, etc., the size is made smaller and the assembly adjustment is made easier than when the functions are obtained by multiple prisms.

Title: Memory controller
Inventor: ISHIKAWA KOZO
IPC: G06F12/02
Filed: 1988-05-18
Abstract: PURPOSE:To shorten the time required for storage of data into an original memory by securing such a constitution where the data on the area to be processed at memory access is read and stored into the memories of plural active parts and only the data on those areas that are shared by the active parts are sent to the original memory after said data are processed by a controller. CONSTITUTION:The addresses of a memory 1 is divided into plural groups in accordance with the number of active means. A data reading line led from each group is connected to the input of a memory means 2 of each active means 3 via a multiplexer 4. At the same time, a data writing line led to each group is connected to the output of the means 2 via the multiplexer 4 respectively. As a result, a reading means 8 can read the same contents of the memory 1 to each means 2 in a reading state of the contents of the memory 1. While a writing means 9 can write independently the contents of the means 2 into the addresses of each means 3 when the data are written into the memory 1. Thus the processing speed is improved for a system as a whole just with addition of a small number of peripheral parts.

The shot data is sent to a bit map memory 6 (11) which has been cleared to zero, where it is converted to a shot image 12 and recorded. Among the data written in the memory 6, only the data used actually are again developed by the developing circuit 4 to shot data 13 and the address of a proximity effect affecting range 14 is calculated by an irradiation quantity computing circuit 7 and sent to the memory 6. The memory 6 reads out these data successively in a work line unit 15 and convert them into bit number data. Simultaneously, the bit number data is multiplied by a proximity effect coefficient to obtain a quantity of proximity effect on the subject word line, and an appropriate irradiation is recorded in the disk 2. When all the necessary processing operation is finished, the switch 5 is changed over to the printing mode so that the pattern data in the memory 3 are developed by the developing circuit 4. The data are sent to a stage control system and electron beam deflecting system 9, and blanked by a blanking system 10 according to the data from the irradiation memory 8, so that the electron beam drawing is performed effectively.

IPC: H01L21/225
Filed: 1987-05-19
Abstract: PURPOSE:To prevent the dispersion of impurity diffusion concentration by treating a diffusion source layer with plasma by a gas mainly comprising oxygen before thermal diffusion treatment. CONSTITUTION:A coating fluid for forming an silica group film containing an impurity source for diffusion is applied in specified film thickness through a conventional method such as a spinner method, a dipping method, a spray method, a brush coating method, etc., onto a semiconductor substrate such as an silicon wafer, and dried at a temperature of 200  deg.C or lower, thus shaping an impurity diffusion source layer. The impurity diffusion source layer is treated with plasma by a gas mainly comprising oxygen. The impurity diffusion source layer is treated with plasma, and thermally treated at a temperature of 1000  deg.C or higher, thus uniformly diffusing an impurity into the semiconductor substrate. The impurity diffusion source layer is baked at a temperature of 300-800  deg.C before heat treatment, thus further inhibiting the dispersion of impurity diffusion concentration.

Title: Semiconductor laser with external resonator
Inventor: MIYATA HIDEYUKI
IPC: H01S3/08
Filed: 1988-05-19
Abstract: PURPOSE:To make the width of an oscillation spectral line of an LD narrow stably by making an optical fiber into a single polarization fiber and by letting a polarization face of the light output from a semiconductor laser be in accord with a proper polarization face of the single polarization fiber. CONSTITUTION:A polarization face of the light 3 emitted from a semiconductor laser 1 is usually parallel with a junction face of the semiconductor laser 1 (x direction). When the polarization face of the emitted light 3 is in accord with a polarization face of the reflected feedback light 4 from an external resonator, both lights interfere with each other with the maximum interference efficiency. When the polarization face of the reflected feedback light is vertical (y direction) with the polarization face of the emitted light 3, both lights do not interfere at all. This is the reason why the polarization face of the light emitted from the semiconductor laser gets in accord with the proper polarization face of the single polarization fiber. Therefore, the polarization face of the emitted light gets always in accord with the polarization face of the reflected feedback light; thereby, both lights interfere with each other with the maximum interference efficiency stably with the passage of time. As a result, the width of a spectral line can be made narrow stably.
