Title: Manufacture of photosensor
Inventor: HARADA YOICHI
IPC: H01L31/0264
Filed: 1989-06-14
Abstract: PURPOSE:To improve photoresponse speed by exposing a film, which is formed by depositing specified concentration of powder of CdS, CdSe, and Cu salt sintered and solidified, to the steam of CdCl2 at 400-500 deg.C for 10-100 hours. CONSTITUTION:A film, which is formed by sintering and solidifying the mixture of 10-90mol% CdS and CdSe and 0.01-2mol% Cu salt and using this powder as evaporation source, is exposed to the steam of CdCl2 at 400-500 deg.C for 10-100 hours for activation. If the time for activation is 10 hours or less, crystallization is insufficient, and response speed is great, while if it is 100 hours or more the currents become too small, and circuit cost becomes high. Moreover, if the temperature for activation is 400 deg.C or less, Cu does not enter the lattice point, and the steam of Cl is insufficient and the quantity of it which enters the film is insufficient, so enough photosensitivity cannot be gotten, while if it is 500 deg.C or more the currents become too small. Hereby, short response time can be obtained.
