Title: Image pickup device
Inventor: ITOU YUUICHIROU
IPC: H01J31/49
Filed: 1983-09-28
Abstract: PURPOSE:To obtain an image pickup device which has a two-dimensional detector and in which a large number of picture elements can be formed by scanning an electron beam over p-n junction arrays formed on a thin semiconductor film sensitive to infrared rays. CONSTITUTION:When an electron beam (EB) is scanned over the screen (B) after a negative voltage is applied to a p type InAs1-xSbx semiconductor layer 2, the electric potential of n<+> areas 3 deviates toward the positive side as compared with the p type semiconductor layer 2, the p-n junction is placed in the reverse- bias state and a depletion layer extends from the p-n junction. Next, when infrared picture signals (IR) become incident upon the screen (A), photons are absorbed by the p type semiconductor layer 2 to produce electron hole pairs in a direct proportion to the intensity of infrared rays since a GaSb base plate 1 is transparent to infrared rays. The electrons are then accumulated in the depletion layer of the p-n junction to increase the electric potential of the n<+> type areas 3 in correspondence to the intensity of incident light. After a given time, an electron beam (EB) is scanned over the screen (B) and changes in the current of the electron beam (EB) are read out as signal currents.

Abstract: PURPOSE:To make evaluation accurate, by increasing the temperature of a semiconductor substrate at a temperature increasing rate of less than 14 deg.C per minute from the first temperature region of 500-900 deg.C, oxidizing the substrate for a specified time in the second temperature region of 1,000-1,200 deg.C, and examining the yield of the number of defects in the crystal. CONSTITUTION:A silicon wafer to be evaluated is inserted in a heat treating furnace, in which temperature is increased to 750 deg.C in a low temperature region TL and O2 gas flows. The temperature of the furnace is increased at a temperature increasing rate RU2of 14 deg.C/min. When the furnace temperature reaches a high temperature region TH of 1,100 deg.C, the gas is changed to specified wet oxygen. After oxidizing treatment is performed for a specified time (e.g. for 60 minutes), the flowing gas is changed to N2. Then the furnace temperature is decreased at a temperature decreasing rate RD2 of about 5-10 deg.C/min. When the furnace temperature reaches the low temperature region TL of 750 deg.C, the silicon wafer is taken out of the furnace. Thus, the defect density of the single crystal silicon can be correctly evaluated, and the manufacturing yield rate can be improved.
