Title: Semiconductor photodetector
Inventor: OKAZAKI HARUHIKO
IPC: H01L31/10
Filed: 1987-07-17
Abstract: PURPOSE:To obtain a PIN type semiconductor photodetector which has a high break down voltage at a low dark current and is large in its light-receiving sensitivity, by diffusing/forming a p-type semiconductor layer of a first n-type semiconductor layer more deeply than a p-type semiconductor layer formed in a second n-type semicon ductor layer. CONSTITUTION:A recessed part 11a is formed in the central part of an upper surface of an n<+> -InP substrate 11. A recessed n<+>-InP buffer layer 12 is formed laminarly inside this recessed part 11a, and besides an n<->-InGaAs light-absorbing layer 13 is formed laminarly inside a recessed part 12a formed inside the buffer layer 12. Namely the buffer layer 12 and the light-absorbing layer 13 are made to grow epitaxially in order, and next a sulfuric acid etching solution is used to remove a surface of the light-absorbing layer 13. An SiNX film 15 is piled and it is patterned in a circular shape by the use of an AZ-resist or the like. The SiNX film 15 is etched by a chemical dry etching method, and next the SiNX film 15 is used as a mask to perform selective diffusion of p-type impurities of Zn or the like. Since a diffusion speed for the InP buffer layer 12 is about twice as large as that for the InGaAs light-absorbing layer 13, the p-type impurities can be diffused to the buffer layer 12 more deeply than to the light-absorbing layer 13 by once performing selective diffusion.

Title: Pattern formation
Inventor: SHIMAZU KATSUHIRO
IPC: H01L21/302
Filed: 1988-07-19
Abstract: PURPOSE:To form a pattern having a size smaller than a resolution limit or less of photosensitive resin by forming a coating film on a pattern forming material in an opening, etching the pattern forming material with the film as an etching mask, and removing the film and the mask film to form the pattern.

Then, with the film 22 as an etching mask the material 20 is etched. Thereafter, the film 22 is removed in mixture solution of sulfuric acid and hydrogen peroxide, and the film 14 is removed in hydrofluoride solution to obtain a pattern 24.

Title: Spectrophotometer
Inventor: TOKUHARA YASUTAKA
IPC: G01J1/24
Filed: 1983-09-27
Abstract: PURPOSE:To perform readjustment arbitrarily and to make it possible to perform measurement at the maximum sensitivity all the time, by omitting the position adjustment of a photocoupler for maximizing sensitivity so as to omit the succeeding adjustment work of the photocoupler on the user side. CONSTITUTION:A wedge W is put in and taken out of reference luminous flux (r) so that the detected outputs of the reference light (r) and sample light S become equal, i.e., the synchronized rectified outputs become zero. The amount of the movement of the wedge is made to be the measured output. The output light of a monochrometer 4 is inputted into an infrared-ray detector 5. Its output is amplified by an amplifier 6 and synchronously rectified by a synchronous rectifier circuit 7. The rectified output is inputted to a servo controller 12. In correspondence with said input signal, a servomotor M is driven and the wedge W is moved in and out so that the input signal to the servo controller becomes zero. The driving amount of the wedge W is converted into a voltage signal by a potentiometer P and recorded as absorption spectrum of the sample. Since the position adjustment of the photocoupler is not necessary, readjustment can be performed arbitrarily, and the measurement can be always performed at the maximum sensitivity.

In this case, the area of this cover plate 9 is set at 70-85% of the area of the melt surface 3a and the tilt angle of the plate 9 is set so as to make the respective flow rates of the gas at the entrance and exit above the melt surface equal to each other, and as the single crystal 7 is pulled, the space between the plate 9 and the melt surface 3a is gradually increased while retaining the tilt angle to proportionately slow down the flow of the gas on the melt surface. Under these conditions, the silicon single crystal 7 is pulled.
