Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent the corrosion of a heat exchanger by installing an oxidizing agent decomposing means for decomposing an oxidizing agent in high temperature treatment water and introducing high temperature water discharged from the means into the heat exchanger. SOLUTION: Raw water, after being heat-exchanged with decomposition treatment water by a heat exchanger 1 and heated to 130 deg.C by a heater 2, is added with 160 ppm of Na2 S2 O8 as an oxidizing agent, and passed through a first reaction tower 4 and a second reaction tower 4 in turn to be subjected to a heat decomposition reaction. After that, high temperature decomposition treatment water is passed through a high temperature active carbon tower 5 of an oxidizing agent decomposing means filled with 0.5 L of granular or fibrous activated carbon to remove the residual oxidizing agent. Water (130 deg.C) discharged from the activated carbon tower 5, after being heat-exchanged with raw water in the heat exchanger 1, is discharged outside the system. In this way, the heat exchanger 1 can be protected effectively from corrosion by the oxidizing agent.

Abstract: PURPOSE:To assure the reproducibility of etching rate by a method wherein the etching process is performed while keeping the DC bias values generated simultaneously with the plasma production between a substrate to be processed and a counter electrode at specific value by controlling the etching gas pressure inside an etching chamber. CONSTITUTION:DC bias values generated between an etching stage (cathode) 4 and a counter electrode (anode) 7 during etching process, i.e., DC bias values impressed on a substrate 6 to be processed are constantly monitored by a DC bias detector 13 to detect the fluctuating values whose signals are transmitted to a motor driving mechanism 14. An exhaust conductance adjusting valve 8 is driven by this motor driving mechanism 14 so that the exhaust quantity may be controlled to change the gas pressure inside an etching chamber 1 in the cancelling direction of DC bias fluctuation (normally declining). Through these procedures, the etching rate can be set up in excellent reproducibility in the preprocessing process such as evaporation, sputtering, etc., in order to form a metallic film used for electrode wiring of a semiconductor device.
