Abstract: PURPOSE:To drive a word line to a selection level at high speed by providing sense amplifiers which drive the word line to the selection level when the level of the word line arrives at a prescribed intermediate level between a non- selection level and the selection level. CONSTITUTION:In a sense amplifier SA1 provided at respective word line terminal at the opposite side of a decoder circuit DCE, a detecting MOSFET Q13 has the intermediate level of the word line between the selection level and the non-selection level, as a threshold voltage. Therefore, by supplying a driving signal from the decoder circuit to a prescribed word line, the MOSFET Q13 is turned on by the slight rising of the level in the word line. Thereby, high level voltage as a good selection level for the word line is supplied from the opposite direction of the propagating direction of the driving signal from the decoder circuit. In this way, the word line can be driven to the selection level at high speed.

Filed: 1995-02-28
Abstract: PURPOSE: To embody evenness which is excellent in low temperature process and reproducibility and smooth in shape in flattening of an interlaminar insulation film. CONSTITUTION: An insulation film 12 is deposited on a substrate 10 on which a wiring 11 is installed and resist 13 is applied thereon and then impurities 14 are implanted from over the resist 13. After the resist 13 is removed, the film 12 is etched. Since the impurities 14 are implanted on the film 12 from over the resist 13, the implantation of the impurities 14 into a recessed part is restrained so that the impurities may be implanted shallowly on an even part of the film 12 and deeply into a projected part of the film 12. Then, the impurities-implanted insulation film 12 is removed by isotropic etching. It is, therefore, possible to produce a smooth and even surface, because the isotropic etching is carried out to the corners of the recessed and projected parts.
