Title: Treatment of waste liquid containing organic nitrogen compound
Inventor: TODO FUKUZO
IPC: G21F9/06
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To treat waste liquid with small amount of power by oxidizing and decomposing it without using an oxidizing agent and by using small-sized equipment. SOLUTION: From a waste liquid tank 1, waste liquid 9 consisting essentially of ethanol amine and hydrochloric acid and containing organic nitrogen compounds in which chlorine ions exist is introduced into an electrolyzer 4. Acidic or alkaline liquid is injected from an acid tank 2 or an alkali tank 3 to control the pH value within a range of 5-9, and electrolysis is performed at electrolytic voltage of 4-8V and at current density of 1-30A/dm<2> . At this time, as electrodes, an anode is platinum or lead dioxide and a cathode is platinum or iron or stainless steel. As a result, the waste liquid 9 is oxidized and decomposed from COD concentration of 6000ppm to that of <=20ppm, thus the treated waste liquid can be discharged to rivers without using an oxidizing agent and with a small amount of power by using a small-sized electrolyzer.

Title: Wafer-dicing device
Inventor: MIMATA TSUTOMU
IPC: H01L21/78
Filed: 1985-03-11
Abstract: PURPOSE:To facilitate the release of wafers after dicing by a method wherein a wafer is removed from an adsorption table by blowing a gas or a fluid out of the attraction table after dicing work. CONSTITUTION:A wafer finished in dicing is released from the vacuum attraction produced by a dicing table, and air is blown on the wafer through an air blast hole provided separately from the vacuum intake of the dicing table. Thereby, the wafer is levitated from the dicing table, attracted by a Bernoulli's chuck standing by above, and fed to the next process of washing. This process unnecessitates hand works and can prevent the mechanic damage of wafers.

Abstract: PURPOSE:To form a highly accurate pattern with the life time of a substrate crystal being maintained, by dry-etching the specified portion of a metal film on the surface of a semiconductor substrate to a specified depth, then, wet-etching the rest of the film. CONSTITUTION:An Al layer 5 is formed through an SiO2 film 4 on an Si substrate in which a diffused layer is formed. A resist mask 6 is applied, and the majority of the area of the Al layer 5 is removed by the dry etching utilizing the plasma sputtering of a mixed gas comprising CCl4 and Ar, and an Al layer 8 is remained. Since the Al layer 8 absorbs the ion impact, damages of the crystal of the substrate 1 are not caused. Since the Al layer is not separated, the potential is not increased even though the layer is charged, and the crystal defects are not induced. Then, the thin layer 8 is wet-etched by H3PO4 and the resist is removed. In this method, the damages and defects of the crystal are not caused, and a highly accurate fine pattern can be obtained without reducing the life time. If the Al layer 5 is grounded, and the substrate 1 is placed on a table 1 whose potential is negative with respect to the ground, a more accurate pattern can be obtained.
