Title: Method of manufacturing semiconductor transistor
Inventor: ASADA KUNIYASU
IPC: H01L29/78
Filed: 1989-12-29
Abstract: PURPOSE:To make it possible to form a mushroom gate whose shape and properties are stabilized by laminating a similar kind or a dissimilar kind of an insulation film on an insulation film and carrying out wet etching in such a way that a predetermined leg forming section for the mushroom gate of both insulation films reaches a semiconductor substrate. CONSTITUTION:A similar kind of insulation film is grown on a pattern-formed insulation film. An insulation film 6 thus obtained is subjected to anisotropic etching by e.g. dry etching. At that time, an attempt is made to stop etching so that the etched bottom of the insulation film 6 does not reach a semiconductor substrate 1. Then, when the insulation film 6 is subjected to wet etching, the etched bottom reaches the semiconductor substrate 1. However, a photoresist 5 is used as a mask for the etching as it is. Then, metal which is designed for a gate electrode is deposited all over the surface by e.g. vapor deposition, and a mushroom-shaped gate electrode 7 is formed by the resist lift-off process. This construction makes it possible to form a mushroom gate whose shape and properties are stabilized.

Filed: 1991-12-24
Abstract: PURPOSE:To obtain a matrix arithmetic unit which can shorten a processing time even when an operation is executed by blocking a circuit by generating a circuit matrix for an operation with a circuit block element removing a com mon arithmetic circuit block. CONSTITUTION:When circuit block information is inputted, whether its circuit block is a global node or not is identified by a circuit block dividing arithmetic part. The block identified as the global node is a common connecting circuit for which many circuit blocks such as a DC supply power source circuit block, a MOS substrate circuit block, a ground circuit block are connected in common. In such a manner, the discriminated global node is removed and a circuit matrix is generated by only other circuit blocks. Also, from the circuit matrix, a circuit equation is generated and formulated by a correcting nodal point method, and subjected to reordering as the circuit matrix again. Subsequently, by eliminating the global node and executing an operation in a circuit matrix processing process, the processing time is shortened.
