Title: Chip removing method for saw machine and its device
Inventor: MORIYA KIKUO
IPC: B23D55/00
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a chip removing method for a saw machine and its device which can lessen a cut bent to prolong the service life. SOLUTION: When chips on a saw blade BS are removed by making a circular wire brush 51 rotated by a wire brush rotary mechanism 55 a but against an edge of the saw blade BS, a rotational direction is determined by a rotational direction determination means 83. The rotational direction determination means 83 controls the wire brush rotary mechanism 55 so that the wire brush 51 can be rotated in a direction to make an opposite side to the cut bent direction of the edge of the saw lade BS abuts on at first. Otherwise, the rotational direction determination means 83 controls the mechanism 55 so as to invert the rotational direction of the wire brush 51 when an amount of the cut bent exceeds a prescribed level range.

Filed: 1991-10-29
Abstract: PURPOSE:To improve data holding characteristics of a memory cell, by making contact holes in the peripheral circuit part shallow, improving wiring reliability, and enabling elimination of interfacial level in a memory cell part. CONSTITUTION:Since an SiN film 34 exists in a peripheral circuit part 12, an SiO2 system film therein can be selectively eliminated by etching using the SiN film 34 as a stopper, when the SiO2 system film as an interlayer insulating film is formed on the SiN film 34. As a result, contact holes are shallow. Since the SiN film 34 does not exist in a memory cell part 11, hydrogen is introduced as far as the Si interface of regions 45, 46 by hydrogen annealing, and the interfacial level in the regions 45, 46 can be eliminated.
