Title: Detachable attachment of rubber support
Inventor: MOTOME YOSHIMASA
IPC: H05K5/02
Filed: 1987-09-30
Abstract: PURPOSE:To easily mount a rubber support by pressing it by means of a stepped rod into the mounting hole of a chassis when it is mounted in the hole of the chassis. CONSTITUTION:The upper end of a rubber support 31 is abutted from below against a mounting hole 33, and the pressing shaft 37 of a stepped rod 36 is inserted into the hole 36 of the rubber support 31. The rod 36 is pressed thereby to elongate its protrusion 34 elevationally, and the outer diameter of the protrusion 34 is reduced to the degree to be engaged within the hole 33. The protrusion 34 is engaged within the hole 33 to become a state protruding above the hole 33. The shaft 37 is pulled out of the hole 35. The outer diameter of the section 34a becomes larger than the inner diameter of the hole 33, and the section 34b disposed in the hole 33 is brought into pressure contact with the inner face of the hole 33. It is engaged in a state that a chassis 32 is intruded into the leg 31, and the rubber support 31 is mounted. Thus, the rubber support 31 can be easily mounted.

Title: Contamination preventing method and cleaning method of silicon substrate surface and device thereof
Inventor: ISHIDA HIROYUKI
IPC: H01L21/3065
Filed: 1989-09-27
Abstract: PURPOSE:To enable a contamination preventing of an Si substrate without generating a dislocation and the like by treating an Si atom on the surface of the Si substrate with a hydrofluoric acid. CONSTITUTION:An Si substrate surface is treated with a chemical, and organic substance and metal atoms are removed. Thereafter, by dipping the Si substrate in the aqueous solution of a hydrofluoric acid, non-coupling hands of an Si atom 1 on an elementary surface are terminated with hydrogen atoms 2. Thereby, the contamination of the Si substrate can be prevented. Also, the light of 20-40eV is irradiated on the Si substrate surface subjected to the treatment in an ultra high vacuum and the hydrogen preventing the contamination of the Si substrate surface is subjected to a desorption at a room temperature. Thereby, the cleaning of the Si substrate surface can be performed without heating the substrate and therefore, a dislocation and the diffusion and desorption of a dopant in the substrate can be prevented.
