Abstract: PURPOSE:To make it possible to prevent a drop in light transmittance of a quartz plate accompanied by wafer treatment by mounting a protection light transmission member to the center on the inner side of a chamber for the light transmission member so that they may come into close contact with each other when processing a semiconductor. CONSTITUTION:Laser light is applied to a wafer loaded in a chamber by way of an approximately semipherical protection light transmission member 10 having a hollow cylinder-shaped projection 10b installed in the chamber. At that time, a base 10a and the projection 10b are integrated by quartz. The protection light transmission member 10 is mounted on a light transmission member (quartz plate 6) in close contact so that the projection 10b may be located at the center of the surface of the light transmission member in the chamber, thereby protecting the quartz plate from direct contact with ionized gas generated during the treatment of wafer. This construction makes it possible to prevent a drop in the light transmittance of the quartz plate 6 and moreover enhance the rate of operation.

Title: Production of electrolytic copper
Inventor: KUKIYAMA KAZUTO
IPC: C25C1/12
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To produce electrolytic copper having an improved quality and appearance and to carry out electrolytic operation stably in high productivity by electrolyzing by the use of an electrolytic bath having a shielding material between the anode and the cathode at the upper part of the electrolytic bath. SOLUTION: The electric current between the anode and the cathode at upper part of the electrolytic bath can be decreased by installing the shielding material between the anode and the cathode at upper part of the electrolytic bath so that the excess deposition of copper on the upper part, i.e., the part near the surface of the electrolytic liquid, of the cathode and the excess dissolution at upper part of the anode are avoided. The shielding material can be installed either on the anode or on the cathode in capped form or installed at the central position between the electrodes. It is preferable to cap the anode in the case of electrolytic refining of copper because the anode is exchanged with lesser exchange frequency than that of the cathode.  The substance having an excellent electro-insulating property and a chemical resistance is preferably used as shielding material, e.g. the materials formed with polyvinylchloride, polypropylene, etc., are preferable.
