Filed: 1985-02-14
Abstract: PURPOSE:To make it possible to perform the anisotropic etching without damages on the surface of the substrate to be treated and increase the cleanliness of the surface after etching treatment. CONSTITUTION:As the base body 15 to be treated and as the reaction gas, Si substrate and XeF2 are used, respectively. The base body 15 to be treated is put on the cooling mechanism 16 in the vessel 11, and cooled nearly to the temperature of liquid nitrogen. When XeF2 gas is introduced into the vessel 11, it adheres on the surface of the base body 15, and forms the Si-F compound layer 21a as the result of reaction with Si surface. By irradiating a light thereto, the irradiated part of the Si-F compound layer 21a is evaporized in the gas phase, and at the same time, XeF2 newly adheres on the exposed surface of Si substrate to form the Si-F compound layer 21a. By repeating the formation of the Si-F compound layer 21 and the evaporation of the compound layer 21a, the etching is progressed and the base body 15 is subjected to the selective etching.

Filed: 1982-02-23
Abstract: PURPOSE:To obtain the velocity of a moving object with a simple mechanism by supplying a velocity detection signal of a Leonard controller to a plurality of field windings which has a measuring generator to match the direction of a plurality of axes of coordinate corresponding to each thereof. CONSTITUTION:The x-axis component and the y-axis components of the velocity of a moving object are detected with two Leonard velocity control systems and ex and ey are outputted separately.

Title: Optical fiber cord
Inventor: KASHIWATANI KUNIO
IPC: G02B6/44
Filed: 1987-02-10
Abstract: PURPOSE:To facilitate handling and to prevent transmission characteristics from deteriorating by using a metallic pipe which is closed in the circumferential direction and has a <=2mm external diameter and a >=30m code unit length. CONSTITUTION:An optical fiber cord uses the metallic pipe which is closed in the circumferential direction and has the <=2mm external diameter and >=30m cord single length. An optical fiber may be made of glass or resin and has no flaw in the outer periphery of the core part and in the inner periphery of the clad while having high transparency.

Title: Pattern forming method
Inventor: HOSOKAWA YOSHIKAZU
IPC: G03F7/20
Filed: 1988-02-10
Abstract: PURPOSE:To improve resolution in a peripheral circuit region and to decrease the number of steps without extremely decreasing throughputs, by using reducing or expanding step exposures having the different magnifications, performing the reducing exposure only in a region requiring high resolution, and performing the equal or expanding exposure in a region where high resolution is not required. CONSTITUTION:In a divided part 11 in a display region, resolution is not so small. Therefore, equal exposure or expanding exposure can be used. The exposing area at one time can be made large. In divided parts 12 and 13 in a peripheral circuit region, many transistors constitute complicated circuits. Therefore, resolution is small, and overlapping accuracy is required. For this reason, reducing exposure is required. In a wiring region 14, high resolution is not required, and equal exposure or expanding exposure can be used. When magnification is changed and the reducing or expanding exposure is performed based on the performance of the circuit of each region and the required resolution, a pattern having the small resolution can be machined highly accurately in the required region. In this way, the decrease in throughput as a whole can be prevented.
