Title: Semiconductor device and manufacture thereof
Inventor: KAWAKAMI SUMIO
IPC: H01L21/76
Filed: 1987-05-13
Abstract: PURPOSE:To improve the degree of integration and performance by a method wherein a first groove narrower than the depth of the groove and a second groove wider than the depth of the groove are formed to a substrate, the stepped section of the first groove and the second groove is buried with a first insulator and the flat section of the second groove with a second insulator, the surface is flattened and an element isolation region is shaped. CONSTITUTION:An silicon oxide film 22 is deposited as a first insulating film, and a section as an element forming region is etched and a substrate 21 is etched, using the oxide film 22 as a mask. When a dense silicon oxide film the same as the first insulating film is deposited on a groove stepped section as a second insulating film and an accurate silicon oxide film 24 on a flat section, a cavity 25 is formed. Since the etching rate of the oxide film 24 is faster than the oxide film 22 by thirty or forty times, the oxide film in the groove stepped section is removed selectively through etching by the mixed liquid of hydrofluoric acid and ammonium fluoride, the oxide film 22 is side-etched at the same etching rate as the stepped section from the side wall of the stepped section, and the oxide film 24 on the element forming region is also gotten rid of and the groove width of the taken-off oxide film is kept approximately constant. The stepped section is buried with thermal oxide films 26, 27, and the surface is flattened.

Abstract: PURPOSE: To safely hold a capsule during mixing regardless of the shape thereof and to simplify handling while easily inserting and detaching the capsule by determining the dimension of a pin and that of a hole part so that the pin is engaged with the hole part by the tilting moment generated by elastic force acting at a capsule holding position. CONSTITUTION: A pin 10 is attached to the lower part of an arm 2 and almost parallel to the shaft of a capsule 5 and pierces the hole part 11 provided to a disc 12 inserted in other arm 1. A spiral spring 13 surrounds the pin and one end part of the spring is pressed by the surface on the side opposite to the arm 2 of the disc 12 and the other end part of the spring is pressed by the holding ring for attaching one end part of the pin 10 to a fork-shaped protruding part 17 of the arm 2. Both arms of a fork are separated to insert a capsule and the force necessary for taking out the capsule is only a force necessary for inclining both arms of the fork when both end parts of the capsule is engaged.  Since the pin provided to the arm is engaged with the interior of the hole part 11 provided to the other arm, the capsule is automatically held by engaging action and acceleration force generated during mixing work increases tilt and self-engaging effect is obtained.
