Abstract: PURPOSE:To substantially secure sufficient strength in wire-bonding and die- bonding of an electrode by a method wherein the electrode surface of a semiconductor element is exposed to the chemical containing hydrogen chloride before performance of a bonding process. CONSTITUTION:When the gallium-containing compound semiconductor and a semiconductor element having a metal electrode containing Au are formed, processes 11 and 13 in which the surface of the metal electrode is exposed to the chemical containing hydrogen chloride are provided.

Title: Thrust balance device
Inventor: KUBOTA KOJI
IPC: F04D29/22
Filed: 1999-04-08
Abstract: PROBLEM TO BE SOLVED: To appropriately keep a thrust balance by providing a uniform pressure portion communicating with an annular groove formed so as to surround a rotating shaft to which an impeller is attached to decrease a flow passage resistance of a fluid in a thrust balance chamber. SOLUTION: Since a fluid itself existing in a thrust balance chamber 15 is rotated accompanying with a rotation of an impeller 6, the fluid has an angular momentum and a flow passage resistance is generated. When the flow passage resistance is big, a fluid does not rapidly flow from a variable orifice 16 even if a space of the variable orifice 16 is increased. Therefore, an annular groove 17 and a uniform pressure groove 18 are provided. A fluid having no angular momentum flows from the uniform pressure portion 18 into a thrust balance chamber 15 through the annular groove 17. The angular momentum of the fluid in the thrust balance chamber 15 is outstandingly decreased by mixing the fluid with a fluid having an angular momentum. Thereby, the fluid in the thrust balance chamber 15 rapidly and smoothly flows out through the variable orifice 16.
