Title: Optical information recording medium
Inventor: KOYAMA EIJI
IPC: G11B7/24
Filed: 1989-11-30
Abstract: PURPOSE:To obtain such a medium that has high recording sensitivity and long life and can be easily formed by forming a base layer comprising such a material containing two kinds of reaction groups, one group to cause crosslink polymn. by radiation or heat and the other group to cause crosslink polymn. with the resin material which constitutes a UV-curing resin layer. CONSTITUTION:The medium consists of a transparent substrate 1, UV-curing resin layer 2, and base layer 3 and recording layer 4 successively deposited on the layer 2. The material for the base layer 3 contains two kinds of reaction groups, one group to cause crosslink polymn. by radiation or heat and the other group to cause crosslink polymn. with the resin material which constitutes the UV-curing resin layer 2. After a stamper is coated with the material for the base layer, crosslinking reaction is effected by radiation or heating to increase insoluble property of the layer, while the reaction group on the surface of the UV-curing resin layer 2 and the reaction group on the surface of the base layer 3 are made to react to crosslink polymn. to improve adhesion property of the UV-curing resin layer. Thus, the obtd. optical recording medium having high recording sensitivity and long life, can be easily obtained.

Title: Semiconductor integrated circuit device and manufacture thereof
Inventor: SHIMIZU JUNZO
IPC: H01L21/768
Filed: 1986-12-27
Abstract: PURPOSE:To improve the step coverage of an upper layer wiring by opening a via hole in a multilayer interconnection structure equal to or more than the width of a lower layer wiring and by locally reducing the thickness of the lower layer wiring at the via hole. CONSTITUTION:A silicon oxide film 1 is formed as a protecting film on a semiconductor substrate wherein semiconductor elements are formed, and the first aluminum layer 2 is formed after a contact hole is opened in the silicon oxide film 1. An insulating film 3 is formed on the aluminum layer 2 and an aluminum film 4 for mask is formed. Then, a photo resist 5 is formed and a via hole is opened by selectively etching the film 4 by using the photo resist 5 as a mask. Then, after the photo resist 5 is peeled, the insulating film 3 is isotropically etched to a thickness of approx. 1/2 by using the film 4 as a mask. Then, the remaining 1/2 thickness of the insulating film 3 is anisotropically etched by using the film 4 again as a mask. Successively, after the film 4 is removed by anisotropic etching, the second aluminum layer 6 is formed. This can easily form a lower layer wiring and can improve the step coverage of an upper layer wiring.

Title: Optical semiconductor device
Inventor: MATSUDA MANABU
IPC: G02F1/23
Filed: 1988-12-06
Abstract: PURPOSE:To control selection wavelength without having dependency on polarization planes by providing a waveguide part having a circular section to allow the passage of only the light of the prescribed selection wavelength among incident light rays and a current injection part which injects current to the waveguide part and changing the selection wavelength by the injection current. CONSTITUTION:The incident light is made incident from an optical fiber 26 and is passed through a clad layer 15, a filter layer 14 and an InP substrate 10, by which the light is so filtered as to allow the passage of only the light of the selection wavelength lambda. This light enters, as exit light, the optical fiber 28. Since the section of the waveguide part 12 constituted of the clad layer 15 and the filter 14 has the circular shape, the guiding mode of the incident light is prevented from varying with the polarization planes and there is no dependency on the polarization planes. The injection current I by applying of a voltage between electrode layers 22 and 24 flows mainly in the waveguide part 12 as there is a current confining layer 16. Since the InP layer and InGaAsP layer have the characteristics that the refractive index varies with the magnitude of the current I, the selection wavelength lambda to be filtered varies with the magnitude of the injection current. The adjustment of the selection wavelength lambdato a desired value is possible in this way.
