Title: Semiconductor photodetector
Inventor: YASUDA KAZUTO
IPC: H01L31/107
Filed: 1982-12-29
Abstract: PURPOSE:To detect light at extremely high speed with high sensitivity by utilizing an energy barrier generated in a valence band in the hetero-interface between InGaAsP and InP. CONSTITUTION:An N type InGaAsP bias light absorption layer 2 is formed on an N type InP substrate 1, and an N type InP carrier confinement layer 31 is formed on the layer 2. When reverse bias voltage is applied to a photodide with a P type diffusion layer 32 in a light-receiving region in the confinement layer 31, the energy barrier is generated in the valence band in the interface between the layer 2 and the layer 31. The magnitude of the barrier depends upon bias voltage and a composition ratio of InGaAsP and changes within a range of 0.2- 0.5eV, and covers optical energy in a wave band of 2-3mum. A bias light 9 having a wavelength of approximately 0.9-1.7mum is irradiated at all times, and light having a wavelength of 2-3mum can be detected at high speed with high sensitivity.

Title: Production of phase transition type optical recording film
Inventor: ABE TAKAYUKI
IPC: C23C14/34
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To produce a film by a DC sputtering method without generating arc discharge and to decrease the production cost by forming a film by a DC sputtering method in the pressure range between >=0.3mTorr and <=3mTorr. SOLUTION: When the gas pressure is changed while the discharge current is kept const. in a DC sputtering method, glow discharge is possible over >=0.3mTorr gas pressure. The min. gas pressure necessary to generate glow discharge depends on the discharge current, distance between the target and a substrate and intensity of a magnetic field. Therefore, by performing DC sputtering in the pressure range above described, a film can be stably formed by sputtering without generating arc discharge during the film forming process. Thus, films can be formed on the surface of a substrate or on a film forming surface without causing damages, and the film thickness can be easily controlled.

Abstract: PURPOSE: To determine a thickness of thin layer deposit by setting a reference light emitting body on a shunt pipe and a light detector at an opposite position and supplying thin layer forming agent when absorbance in a reference section and a sample section reaches a predetermined value. CONSTITUTION: A light amount of a light emitting body 16 of a sample transducer(ST) is weakened by a thin layer 14E interposed in a pipe 12 for outputting a potential signal VS corresponding to an analog value of the light amount. A reference transducer(RT) is set downstream the ST, a sampling pipe is kept clean by a wiper 26, a light emitting body 20 is placed oppositely to a light detector 22, and a voltage analog value VR is output.
