IPC: H04N5/335
Filed: 1985-09-03
Abstract: PURPOSE:To protect a lower electrode from corrosion and disconnection and thereby to improve the yield rate by a method wherein a photoetching process for an upper electrode is accomplished through corrosion in the production of a solid-state image pickup device, constituted of upper electrodes and lower electrodes and amorphous semiconductor layers sandwiched between them, installed on an insulating substrate. CONSTITUTION:A lower electrode of Al-Si alloy 11 is formed on an insulating substrate by sputtering, which is followed by photoetching. Next, an amorphous semiconductor layer 12 is formed, whereon an upper electrode of ITO film 13 is formed by sputtering, whereon a photoetching resist is further formed for the photoetching of the ITO film 13. Aluminum is then deposited by evaporation. Use of an alkaline solution for etching results in electrolytic corrosion to etching, in the region where the ITO film 13 and aluminum are in contact. Finally, the amorphous semiconductor layer 12 is subjected to dry etching, and the resist is peeled off for the completion of the manufacturing process. By using this technique, the disconnection in the lower wiring during the photoetching of the upper electrode 13 can be greatly reduced, which contributes to improvement in the yield.

Filed: 1981-12-04
Abstract: PURPOSE:To obtain recording paper free of folding, ruck, and picture disorder by detecting the extent of slanting feed of recording paper at a fixation part and controlling the driving of a fixing roller. CONSTITUTION:When recording paper 4 is fed slantingly, a sensor 11 detects the left corner of the recording paper 4 to generate an output (a). Then, a sensor 12 detects the right corner of the recording paper 4 with some time lag to generate an output (b).

This output signal (c) is inputted to an arithmetic circuit 16 and during this period, a fixing roller 3 is stopped. Simultaneously, the slanting feed is corrected and the off time is so set that the extent of flection is not excessive. As the paper size increases, the off time of an output for driving the fixing roller is extended. Therefore, the trouble of the slanting feed is not caused and an unfixed picture is not disordered.

Title: Semiconductor light-emitting element
Inventor: OKI AKIRA
IPC: H01S5/00
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To obtain a long life of a light-emitting element and an improved element characteristic by setting up a Ge layer forming a superlattice which is gradually the thinner, the further distant from a substrate and by simultaneously forming II-VI group chemical layers forming the super lattice which is gradually the thickener, the further distant from the substrate. SOLUTION: A Ge layer uses a quantum well layer as a buffer layer and a II-VI group compound semiconductor layer uses a superlattice acting as a barrier layer. moreover, the well layer is arranged thinner in proportion with the distance from a GaAs substrate 1 while the II to VI group barrier layer becomes thick. In consequence, the Ge layer has a narrower hand gap than the GaAs substrate 1 so that the Ge layer forms no barrier seeing from the GaAs substrate 1. Accordingly, with a change in thickness of the well layer of Ge and the II to VI group barrier layer a quantum level of a hole to be formed inside the well layer of Ge gradually rises so as to approach a valence electrode end of the II-VI group barrier layer thus relieving a potential barrier between the II-VI group compound semiconductor growth layers.
