Abstract: PURPOSE:To enhance yield and reliability of semiconductor devices through improved etching precision by a method wherein an insulating film or a metal film is provided to cover a protecting film built of silicon nitride not involving a metal electrode forming region and then a wiring is formed out of the metal layer by means of photoresist-etching. CONSTITUTION:An insulating film 15 or metal film 15 is provided on a silicon nitride protecting film 12 covering a smiconductor substrate 11 except on a region for electrode formation and then wiring metal is patterned by photoresist- etching, for the formation of a metal electrode 13 on the silicon nitride protecting film 12. For example, after formation by vapor growth of a silicon oxide film on the silicon nitride protecting film 12 covering the semiconductor substrate 11, the silicon oxide film is removed from the region for electrode formation by photoresist-etching for the formation of the insulating film 15. Next, a metal, aluminum or the like, is attached to the entire surface by spattering or vapor growth, a photoresist film 14 is formed only on the region for electrode formation, and the photoresist film 14 serves as a mask in a process wherein the metal film is subjected to selective dry etching for the formation of a metal wiring electrode 13.

Filed: 1984-04-20
Abstract: PURPOSE:To operate a flip-flop circuit with one transfer clock by providing a data storage circuit and a switch circuit consisting of an MOSFET in the master side as well as the slave side. CONSTITUTION:A signal M of a data storage circuit 6 in the master side turns on a switch circuit 8 and goes to the low level forcibly if an anti-phase input data signal DIN is in the high level and a transfer clock signal CL1 is in the high level. Similarly, a switch circuit 7 is turned off, and the anti-phase signal M goes to the high level. If the input data signal DIN is in the high level, the switch circuit 7 is turned on, and the anti-phase signal M goes to the low level forcibly, and the switch circuit 8 is turned off, and the signal M goes to the high level. Thus, input data DIN can be transferred to the data storage circuit 6 in the master side when the clock signal CL1 is in the high level. Similarly, stored data in the master side can be transferred to a data storage circuit 9 in the slave side when a transfer clock signal CL2 is in the low level. Consequently, this flip-flop circuit is operated with one transfer clock.

Filed: 1986-04-09
Abstract: PURPOSE:To prevent the disconnection of a coil lead wire caused by the vibration by using an energizing means which energizes a movable part in the single direction in a non-drive mode of a compact disk CD player. CONSTITUTION:In a non-drive mode of a CD player the DC voltage is always applied to a focusing coil 20 from an actuator energizing circuit 35 and therefore the lower end plane 32 of a slide bearing 10 is pressed to a stopper 31. This pressing force prevents the up-down movements and the rotation of a bobbin 11.
