Title: Substrate cleaning apparatus
Inventor: SHIRAKAWA HIDEKAZU
IPC: H01L21/304
Filed: 1990-04-03
Abstract: PURPOSE:To easily prevent static electricity without using a large-scale apparatus by providing an apparatus which neutralizes static electricity generated on the surface of a substrate by the cleaning water. CONSTITUTION:When a cup 11 is lowered and a chuck 9 is exposed, a semiconductor wafer 8 is placed on the chuck 9, and is sucked. A nozzle 4 and a brush 7 are moved to the central part of the semiconductor wafer 8 by using a scanner 5. The flow rate of ultrapure water which has been produced with an ultrapure water system 2 and has been stored in a tank 3 is adjusted by using a flow-rate regulating valve V1 and is sprayed, from the nozzle 4, on the surface of the semiconductor wafer 8 as a jet water current. The brush 7 is turned by using a motor 6; the semiconductor wafer 8 is turned by using a motor 10; a cleaning operation is executed. Since the brush 7 is made of a polyfluoroethylene-based material or polyester, static electricity is generated due to friction on the surface of the semiconductor wafer 8 and the surface is electrified positively. However, electrons are discharged onto the semiconductor wafer 8 from a thermion generator 12 and the static electricity is neutralized. As a result, semiconductor circuits on the semiconductor wafer are not damaged by the static electricity.

Title: Joining ceramics
Inventor: YOSHIDA TOSHIHIRO
IPC: C04B37/00
Filed: 1991-03-28
Abstract: PURPOSE:To obtain ceramics joint parts having high bond strength and high airtightness by oxidizing ceramic members to be joined, using an inorganic joining material consisting essentially of SiO2, heat-treating the members in nitrogen and joining. CONSTITUTION:At least two ceramic members to be joined, constituting a ceramics joined material, are oxidized. Then, the members are heat-treated with an inorganic joining material consisting essentially of SiO2 in vacuum and joined. By the joining method, since the ceramic members to be joined are oxidized before joining and joining heat treatment is carried out in the nitrogen atmosphere, the surface properties of the members to be joined, such as wetting to the joining material, are changed. Hardening properties of the joining material are improved with heat treatment in the nitrogen atmosphere to form joint part having few pores and no defects. Simultaneously, borosilicate glass of the joining material is partially changed into oxynitride glass and oxidation of the ceramic members to be joined and joining heating in the nitrogen atmosphere synergistically act.
