Title: Manufacture of semiconductor device, and semiconductor device manufactured thereby
Inventor: HOSHINO KOICHI
IPC: H01L21/306
Filed: 1994-03-04
Abstract: PURPOSE:To obtain a manufacturing method for semiconductor devices whereby the quality of the surface of a semiconductor substrate is not changed even when the photoresists of pre-processes are left on the surface of the semiconductor substrate to be recess-etched or the substrate is subjected to etching, heating and the like. CONSTITUTION:In a manufacturing method for semiconductor devices, a resist 104 to be the mask of a mesa-etching and a photoresist for forming ohmic electrodes 111, 112 by a metal-lift-off are formed not directly on a semiconductor substrate 101, but are formed thereon via an insulation film 102. Further, before the recess-etching of the substrate 101, the insulation film 102 is removed therefrom. Thereby, the qualitative changes of the surface of the semiconductor substrate 101 which are caused by the leavings of the resists on it, the heat generated from its heat treatment and the removings of the resists from it through a chemical etching are prevented.

IPC: G21F9/30
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To stably and easily dispose of a used ion-exchange resin generated from a unclear power play over a long period. SOLUTION: For a used ion-exchange resin generated from a unclear power plant, an operation to separate carbon acid ions and hydrogen carbonate containing C-14 is conducted. The used ion-exchange resin from which carbon acid ions and hydrogen carbonate ions are separated is solidified in a container. H2 SO4 is added to a radioactive separation liquid containing the carbonic acid ions and hydrogen carbonate ions separated from the used ion-exchange resin to control the pH of the separation liquid to 7. The C-14 contained in the separation liquid is gasified and removed from it. After the separation liquid clear of the C-14 is is concentrated, it is poured into a drum and is solidified by a solidifying material. The used ion-exchange resin and the separation liquid do not contain C-14 any more, the can be stored stably and easily in burial facilitates.
