Abstract: PURPOSE: To prevent the re-adsorption of chlorine components to a semiconductor substrate by providing a chlorine component removing mechanism and efficiently removing chlorine components from the substrate by setting the atmosphere of a chamber so that chlorine components can be efficiently removed, and then, preventing the deposition of chlorine components on the interval surface of the chamber. CONSTITUTION: A chlorine adsorbent 10 which is formed in a pellet-like state is fixed to the internal surface of a chamber 1 with a fine-meshed net of SUS, etc. Or, a chlorine adsorbent 10 molded in accordance with the shape of the internal surface of the chamber 1 is fixed to the internal surface of the chamber 1 with a hook, etc. Consequently, chlorine components 7 separated from a wafer 6 do not deposit on the internal surface of the chamber 1, but are adsorbed to the adsorbent 10. Therefore, the re-adsorption of the chlorine components 7 to the wafer 6 can be prevented and the corrosion of aluminum wiring can be reduced. It is possible to coat the whole internal surface of the chamber 1 with the adsorbent 10. The adsorbent 10 is prepared by press forming a mixture of the power of activated carbon, such as charcoal, etc., and various kinds of binders.

Title: File name control system
Inventor: CHINO TOMINO
IPC: G06F12/00
Filed: 1989-03-03
Abstract: PURPOSE:To compress and control a long file name to which the file characteristics are reflected by using a means which compresses and converts a character string into an optional number of characters and a means which performs the reconversion to the duplication of converted character strings. CONSTITUTION:A compression/conversion part 1-2 checks the number of characters of an identification name 1-1 serving as an object of the file control and compresses properly these characters. A duplication processing part 1-3 changes the compressed/converted character string to a prescribed conversion area if the character string overlaps an existing file name. Then a reconversion table 1-4 is added. Thus it is possible to avoid such a case where a controllable file is regulated in terms of the length of the file name 1-5.
