Title: Hydrocarbon thin film
Inventor: RICHARD LONGSRES WHITE
IPC: B32B9/00
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To obtain good adhesiveness and to improve wear resistance by allowing the hydrogen contained in the thin film protective layer on a disk to exist at the lowest atomic % at the part nearest the base material, to gradually increase toward the surface and to exist at the highest atomic % on the surface. SOLUTION: A single layer over-coating 15 has a hydrogenation concn. gradient increasing toward the film surface. The hydrogenation gradient starts from about 25atm.% at the lowermost surface of the film in contact with the magnetic material of the disk. The hydrogenation level in the over-coating 15 increases in the film and is about 35 to 40atm.% at the outside surface of the film. The hydrogen content of about 8atm.% at the lowest level of the film in contact with the magnetic material is the actual threshold and 20 to 30atm.% is practical in production environment. The peeling of the film increases dramatically when the hydrogen content exceeds 35%. The hardness is higher at 20 to 35atm.% than at 10atm.% or 40atm.% of the hydrogen. The practical upper limit of the hydrogenation % is considered to be near 40atm.%.

Title: Semiconductor structure for optoelectronic component
Inventor: JIYANNMITSUSHIERU JIERARUDO
IPC: H01S5/00
Filed: 1991-01-10
Abstract: PURPOSE: To reduce influence of dislocation to the operation of a structure of an optoelectronics element by making a forbidden band of a semiconductor material narrower than a forbidden band of one layer with a three dimensional content in a structure having a plurality of layers in a semiconductor material. CONSTITUTION: Layers 2 to 5 constitute a double hetero structure and layers 2 to 4 are semiconductor materials. A narrow forbidden band BI is between a valence band BV and a conductive band BC, and furthermore, a semiconductor material of layers 2, 4, of high refractive index can be made GaAs. Other two layers 3, 5 have forbidden bands L3, L3 and are semiconductor materials. A width of a forbidden band of L3 and L5 is larger than that of a forbidden band L4 of the layer 4 and its refractive index is low. Here, the narrowness of a forbidden band of the layers 2, 4 depends on relationship to a size of a forbidden band of the layers 3, 5. In the conditions, as is well-known, laser beam which propagates inside an active layer 4 in the middle between the layers 3, 5 is limited by the layers 3, 5.

Title: Measuring system for semiconductor device
Inventor: MIYAMOTO YOSHIHIRO
IPC: G01R31/26
Filed: 1982-01-28
Abstract: PURPOSE:To know the surface potential immediately under an insulation gate by a method wherein a detection amplifier is connected to the electrode insulated from a substrate, thus the surface of the substrate is put into an accumulation state, and the detection output is kept equal to the reference signal voltage, next the potential change generated by the increase of charges stored in a potential well is detected by an energy irradiation. CONSTITUTION:An element Q1 is closed by giving a voltage phiR to a terminal 43, thus the residual charge in the variable capacitor Cf of a charge amplifier CA is removed, and simultaneously an element Q2 is closed by applying phi1 to a terminal 42. The reference voltage VRef is superposed on a voltage VA slightly larger than the voltage VG of the power source 13 and given from a contact C to the substrate 1 resulting in the generation of an electrode 34 on an insulation electrode 34, then an element Q3 is closed by impressing 41 the voltage compensated to the phi1, and the Cf is adjusted resulting in detection and amplification 14, accordingly VOut1= VRef is measured. Successively, the voltage VG is applied from a contact b, thus the surface of the substrate 1 is inversed 1, and accordingly a well 19 is formed according to the voltage VG. When a light 30 is irradiated, a charge 17 is accumulated on the well, thus the fluctuation DELTAphiS of the surface potential is generated resulting in the detection and amplification 14, and accordingly VOut is measured. In this manner, the surface potntial only immediately under the purposed electrode is image-drawn as the function for the VG and can be accurately obtained without the parasitic effect of a vicinity or superposed electrode.
