Title: Manufacture of semiconductor device
Inventor: HIRAKI MITSUMASA
IPC: H01L21/304
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To make the film thickness of an interlayer insulating film constant in chemical-mechanical polishing method. SOLUTION: On a semiconductor substrate 21 on which a wiring pattern is formed, at atmospheric pressure oxide film 25 is formed. A plasma nitride film 24 is grown on the film 24, and a plasma oxide film 26 is grown still further. When the entire surface is etched back by using a chemical-mechanical polishing method, the nitride film on the wirings acts as an etching stopper. The oxide film on non-wiring part is etched no further. The difference In the levels of the wirings part and the non-wiring part is eliminated, and the flattening of the interlayer insulating films can be conducted. By using the nitride film as the etching stopper, the film thickness of the interlayer insulating film becomes constant. Furthermore, since the insulating film thickness on the wiring at polishing can be kept large, stress will not be applied on the wiring, and the reliability is improved.

Title: Sense amplifier circuit of mos memory
Inventor: WADA TOSHIO
IPC: G11C11/419
Filed: 1978-02-23
Abstract: PURPOSE:To obtain a sense amplifier of a MOS memory stable in refresh operation by using a couple of unifirectionally-conductive channel type IGFETs and a couple of reversely-conductive channel type IGFETs with gates and drains connected intersecting. CONSTITUTION:When precharge pulse (phiP) and transfer pulse (phiC) both become high in potential, digit line potentials (vD) and (vD'), and nodes A and B are precharged by intermidiate voltage VR of approximate 2V. Before sense operation, potentials (phiW) and (phiDW) of a word line and a dummy word line become high and power supplies of capacity elements CM and CDM change potentials (vD) and (vD'). Because of the low potential of pulse (phic) and the high potential of (phis), the potential of common source point C decreases; either couple of P-type MOSs QK1 and QK2 or of N-type MOSs Qs1 and Qs2 turn ON, and the other couple OFF. With pulse (phic) and boot-up pulse (phiL) high in potential next, potentials (vD) and (vD') become 4V and OV. When the difference between potentials (vD) and (vD') is the largest, potential (phiW) decreases and refresh operation ends, so that it will operate stably.

Title: Voltage regulator
Inventor: SAITOU AKIHIRO
IPC: H02J7/24
Filed: 1979-02-26
Abstract: PURPOSE: To cut out an exciting current when an abnormal voltage is generated by melting a fuse inserted in a field-winding circuit by an abnormal voltage sensor when the abnormal voltage is generated.  
     CONSTITUTION: When an abnormal voltage is generated in the output of a generator, a current flows through a route comprising a diode 58, Zener diode 59, and a fuse 60. Owing to the ohmic resistance of the Zener diode 59, the power loss in this element is exponentially increased. As a result, the portion between the anode and cathode is instantly conducted and alloyed and the resistance of the portion becomes extremely low. Therefore, a great current flows through the fuse 60, and the fuse 60 is melted, thereby the flowing of the field current is stopped.
