Title: Semiconductor device and method of forming element separating trenches for semiconductor device
Inventor: YAMAMURA YASUHIRO
IPC: H01L21/76
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To reduce the size of a semiconductor device by forming comparatively wide and comparatively deep element-separating trenches at regions requiring a relatively high element-separating power and relatively narrow and relatively shallow element-separating trenches at regions requiring a comparatively low element-separating power. SOLUTION: Using an Si nitride film 11 as a mask, an Si substrate 9 is etched to form trenches 15 of, e.g. 300nm deep, i.e., element-separating trenches 8 of 350nm in width w0 and 500nm in depth h0 and element-separating trenches 12 of 250nm in width w1 and 300nm in depth h1 . The trenches 12 are comparatively narrow and comparatively shallow. Hence an insulation 2 such as SiO2 can be filled, without forming gaps. The trenches 8 are relatively wide and relatively deep, hence an insulation such as SiO2 can be filled, without forming gaps.

Abstract: PURPOSE: To improve the welding quality by correcting the voltage value instructed by a voltage instructor by a voltage correcter from the correction value calculated by a calculator, and outputting the corrected voltage value by an output controller to prevent the bead from being narrowed by the change of the welding speed. CONSTITUTION: A comparator 11 successively compares the welding speed during the welding with the reference welding speed during the welding to obtain the difference between them, and a calculator 12 calculates the correction value by the difference between the welding speeds. The current value instructed by a current instructor 5 is corrected from the correction value calculated by the calculator 12 by a current correcter 13, and a motor controller 7 instructs a wire feed motor 2 to feed the wire at a feeding speed corresponding to the corrected current value. The voltage instructed by a voltage instructor 6 is corrected by a voltage correcter 14 from the correction value calculated by the calculator 12, and an output controller 8 outputs the welding voltage corresponding to the corrected voltage.  The deposit quantity of the wire is kept constant against the change of the welding speed.
