IPC: H01L21/3065
Filed: 1992-04-17
Abstract: PURPOSE:To highly select and anisotropically etch a W-polycide film without using CFC (chlorofluorocarbon). CONSTITUTION:A W-polycide film 5 is etched by using COF2 (carbonyl fluoride)/HBr mixture gas. In this case, since strong chemical bond and electrostatic attraction force are applied to carbon series polymer CBrx to be formed resultantly from decomposed product of a resist mask 6 by introducing carbonyl group (>C=O), a strong sidewall protective film 7 can be formed. Accordingly, incident ion energy necessary for anisotropic processing and deposited amount of the carbon series polymer can be reduced, selectivity of the mask 6 and a gate oxide film 2 is improved, and further particle contamination can be suppressed. When S2Br2 is added to gas and deposition of S (sulfur) is used together, further high selectivity is obtained, and when SF6, etc., is used together at the time of etching a WSix layer 4, an acceleration of its speed is realized.

Title: Semiconductor storage device
Inventor: NAKASE YASUNOBU
IPC: G11C11/34
Filed: 1985-05-07
Abstract: PURPOSE:To read without setting a reading reference electric potential by directly comparing the potentials between respective nodes in a selected memory cell. CONSTITUTION:When a memory cell MC is selected, a base potential of a transistor QR during a reading is made higher than the base potential of QW1 and QW2. At this time, a constant current source IY is fed through QR and QM1 and QM2 forms an emitter connecting logical circuit through diodes D1 and D2 and resistances R1 and R2. During writing operation, when QM1 is turned on and QM2 is turned off, the base potential of QW1 is made higher than the base potential of QR and QW2. Then, by turning on QW1, the current of the constant current source IY is supplied only through a bit line B1. As a result, the allowance to a process parameter or a temperature change during a reading is enlarged and an input potential difference with respect to a sense amplifier can be set to an optional degree.
