摘要： PURPOSE:To obtain a thin film having superior photosensitivity and a high optical response speed, by depositing a thin CdS film having a specified thickness on an insulating substrate by a sputtering method under specified conditions and by heat-treating the film at a specified temp. in an inert gaseous atmosphere. CONSTITUTION:A thin CdS film 2 having 0.5-10mum thickness is deposited on an insulating substrate 1 of glass or the like by a sputtering method at 100- 300 deg.C substrate temp. under 1-20Pa pressure. The film 2 is heat treated at 300-600 deg.C in an Ar atmosphere. It is preferable to carry out the heat treatment in an atmosphere contg. copper and/or chlorine. The film 2 is then formed into a desired shape by a photoetching method, and a metallic electrode film 3 having a desired shape is formed. The whole surface is coated with an insulating protective film 4 of glass or the like to manufacture an optical sensor for unmagnification.

摘要： PURPOSE:To simplify the manufacturing process, and to reduce manufacturing cost largely by forming a gold plating layer to one part on a metallic thin-film as a bonding section. CONSTITUTION:A NiCr layer 2 is laminated onto an insulating substrate 1 made of silicon oxide (SiO2) or ceramics or the like through a vacuum deposition method or a sputtering method. The film thickness of NiCr differs according to the size of the electrode, but it is preferable that it is kept within a range of several hundreds or several thousands Angstrom . The NiCr film is etched to a desired shape through a photolithography method to form an NiCr layer 2. Sections except a section to be plated with Au is coated with a photo-resist (a photosensitive acid-resistant film), and the film surface of the NiCr layer of the section to be plated with Au is treated with an acidic cleaner such as Oxytron No.15 (a merchandise name). The film surface is washed away by wafer, treated with dilute hydrochloric acid, etc., and washed lastly by water once more, and the surface treating of the NiCr layer is completed. The surface is plated with Au through a normal method in a normal bath, and the desired Au plating layer 4 is formed.

CONSTITUTION:SnO2 2 is evaporated on quartz glass 1. The mixture of Se or 50 atomic % or more and As of 50 atomic % or less is heat-treated in a vacuum and then quickly cooled. Thus, the Se-As compound is prepared and evaporated 3 to about 4,000Angstrom on an electrode 2 in the vacuum. Then the compound having more Se or pure Se is further evaporated to about 1.000Angstrom , and a film 4 is layered. If the total thickness of the films 3 and 4 is 2,000Angstrom or less, pin holes will be formed. An Au electrode 5 is provided on the film 4. If Te, P, and the like are added to the Se- As compound as impurities, the performance can be enhanced in response to the purposes. In this constitution, the device characterized by the small leakage currents and the quick response speed can be obtained, and the long dimensions and the large area can be realized.
