Patent JP-S6281752-A (JP)
Title: Semiconductor memory device
Inventor: INOUE HIROSHI
IPC: H01L21/8242
Filed: 1985-10-07
Abstract: PURPOSE:To prevent erroneous operations due to noises, by forming a first plate comprising a conductor film on the wall surface of the inside of a groove. CONSTITUTION:A first plate 22 comprising polysilicon and the like is used as one electrode of a capacitor C1 instead of a conventional inverted layer. Therefore, the formation of the inverted layer, which is a cause of trouble in the conventional device is not required. The impurity concentration and the film thickness of the first plate 22 can be precisely controlled, and the plate can be readily formed. Therefore, a ground potential VSS or an intermediate potential 1/2VCC can be applied to a second plate 25, which is another electrode of the capacitor C1. Thus erroneous operations due to noises can be prevented. Since an electric field, which is applied to a dielectric layer 24 becomes small, the film thickness can be made thin. The capacitance of the capacitor C1 can be made large, and high integration density can be implemented by the reduction in area of the capacitor.

Title: Optical control device
Inventor: KANDA TORAHIKO
IPC: G02B6/36
Filed: 1989-08-29
Abstract: PURPOSE:To shorten the time required for specular finishing of optical waveguide connection end surfaces and to reduce connection loss by forming a protection film, which is smaller in refractive index than optical waveguides, approximates in mechanical performance to a dielectric crystal substrate and is in close control with the dielectric crystal substrate, on the dielectric crystal substate nearby the connection end surfaces of the optical waveguides. CONSTITUTION:The protection film 17 is smaller in refractive indes than the optical waveguides 12 and 13 and similar in mechanical performance to the dielectric crystal substrate and formed in close contact with the dielectric crystal substrate. The protection film 17 is formed on the dielectric crystal substrate 11 nearby the connection end surfaces of the optical waveguides 12 and 13 to a thickness of about several microns and the substrate 11 and protection film 17 are formed in close contact without any inclusion. Consequently, the protection film 17 never peels at the time of a disconnection. Further, the substrate 11 and protection film 17 are similar in hardness as the mechanical performance, so the substrate 11 and protection film 17 form a body which is almost elastically continuous. Therefore, chipping is caused on the protection film 17 at the end part of a cut surface and no large chipping of micron order occurs to the connection end surface part of the optical waveguides 12 and 13. Consequently, the time required for the specular working is shortened and the connection loss is reducible.
