Abstract: PURPOSE:To form a contact hole part in a tapered shape as well as to prevent the increase in wiring resistance and the generation of breakage of wire by a method wherein, after the contact region insulating film layer of the prescribed pattern and a photoresist mask have been formed on a substrate, the insulating layer is etched to its intermediate thickness, then a photoresist film is removed, a polycrystalline silicon layer is formed on the whole surface, the whole surface of said polycrystalline silicon layer is etched, a photoresist mask is formed, and then a contact hole is perforated on the insulating film. CONSTITUTION:After a thick oxide film 2 has been formed on a semiconductor substrate 1, an impurity region 3 having the conductive type reverse to that of the semiconductor substrate is formed. Then, a transistor gate, consisting of polycrystalline silicon or a high melting point metal and the like, a first wiring layer 4 are formed, and subsequently, an interlayer insulating film 5 and the mask pattern, to be used for formation of the first contact hole on the surface of the insulating film 5, are formed. Then, said interlayer insulating film 5 is etched to the depth of about one half of the thickness of the insulating film 5, and the photoresist mask 6 is removed. Subsequently, when an etching is performed on the whole surface after a polycrystalline silicon layer 8 has been formed on the whole surface, a polycrystalline silicon of the width of DELTAW corresponding to the thickness of the interlayer insulating film 5 can be left on the edge part of the contact hole and the stepped part of the interlayer insulating film.

Title: Synchronization detecting system
Inventor: SHIMIZU TAKAFUMI
IPC: H04J3/06
Filed: 1983-11-30
Abstract: PURPOSE:To detect a synchronizing pattern by a small number of hardware and to shorten a detection time by writing data in each frame in a writing/reqding memory (RAM) and matching the written data with a synchronizing pattern written in a read-only memory (ROM) at a high speed. CONSTITUTION:Data in the RAM are successively matched with PN patterns of groups 1-30 in the ROM. When the data in the PN group of the RAM, i.e. data in the 7th area, are matched with the synchronizing pattern, it is decided that a synchronizing signal is located on the 7th bit of the input data. Therefore, ''1'' is set up in the 7th bit of a gate register 11, and when the signal corresponding to the 7th clock in parallel clocks obtained by dividing a clock 4.8KHz by eight is inputted, its output generates a PN clock through an OR circuit 14.
