IPC: C30B23/08
Filed: 1994-04-15
Abstract: PURPOSE:To grow a high-quality semiconductor epitaxial crystal on a substrate by making a feedback control of the amount of dopant gas which is to be supplied to a plasma excitation cell equipmet based on the exited state of the dopant gas found by the current detected by a current detector and the power for generating plasma. CONSTITUTION:At an opening section to a crystal growth chamber 1 of a plasma excitation cell equipment 11 which supplies dopant gas, a grid electrode 22 electrically insulated from the plasma excitation cell equipment 11 is installed. Positive or negative voltage is supplied to the grid electrode 22 from a source of dc 23. The current caused by the voltage is detected by a current detector 24 and the excited state of the dopant gas is judged by the detected current. Based on the excited state of the dopant gas, the amount of the dopant gas to be supplied to the plasma excitation cell equipment 11 and the power for generation plasma are feedback-controlled. By this method, a high-quality II-VI compound semiconductor epitaxial crystal can be grown on a substrate B.

Title: Dynamic semiconductor memory
Inventor: HAYAKAWA GORO
IPC: G11C7/22
Filed: 1995-04-26
Abstract: PURPOSE: To obtain a dynamic semiconductor memory in which low current consumption can be realized without generating any through current under stand-by state. CONSTITUTION: A first logic gate circuit 202 receives an internal row strobe signal ZRASF, an internal column strobe signal ZCASF and a self refresh mode signal ZBBU and outputs an operating state detection signal S. The operating state detection signal S goes 'H' under stand-by state and self refresh state. A second CMOS logic gate circuit 204 is closed when the operating state detection signal S goes 'H'. Consequently, an external I/O control signal EXTZWE is not transmitted to the inside and no through current is fed to the second CMOS logic gate circuit regardless of the level of EXTZWE signal.

Filed: 1989-04-21
Abstract: PURPOSE:To obtain the compact device which is free from distortions in scanning lines by providing a laser light source, a lens, a cylindrical surface, a device for rotating the cylindrical surface around the central axis, and a reflection type hologram which is provided on the cylindrical surface and is varied in space frequency by positions. CONSTITUTION:Laser light emitted from the laser light source 8 is converged by the lens 10 and the reflection type hologram 13 on the cylindrical surface 11 provided between the lens 10 and the convergent point is irradiated perpendicularly with the convergent light. The cylindrical surface 11 is rotated. Namely, the space frequency of the reflection type hologram 13 changes to change the angle of diffraction and to scan the convergent point of the diffracted light within the plane perpendicular to the central axis of the cylindrical surface 11. Since the convergent light is made incident perpendicularly to the cylindrical surface 11, the diameter of the cylindrical surface 11 is not affected by the diameter of a motor 12. The convergent point of the diffracted light passes the deflection point on the reflection type hologram and moves within the plane perpendicular to the central axis of the cylindrical surface 11; therefore, the scanning line is linear. The optical scanner which is low in cost, compact and free from the distortions in straight lines is obtd. in this way.
