Filed: 1993-11-09
Abstract: PURPOSE:To provide a method and an apparatus for preparing a high purity argon without the use of a hydrogenation/deacidification process in an ordinary argon purifying method and further without the use of a high purity argon tower. CONSTITUTION:Air is compressed, refined, cooled, and introduced into a main fractionating tower 51 comprising at least one tower to take out oxygen and/or nitrogen, and argon stock gas with oxygen contents of about several ppm is introduced into the main fractionating tower 51 and is further introduced into an argon fractionating tower 53 of the theoretical stage number of 100 or more preferably of 160 or more for fractionation. Argon gas including nitrogen is taken out by adjusting its amount from a tower top, and high purity fractionated gas or liquid argon is taken out from a portion of the tower below several states or several tens of stages from the tower top and liquified oxygen is taken out from a tower bottom. Refined gas or liquefied argon is further fractionated through adsorption or gettering. In the argon fractionating tower the amount of a reflux is controlled, and the purity of the fractionated argon and the amount of the fractionation of the same are controlled.

IPC: H01L21/027
Filed: 1993-10-13
Abstract: PURPOSE:To prevent the disorder of the pattern shapes of photoresists by dissolving the temperature difference between the periphery of a substrate and the center of the substrate. CONSTITUTION:A substrate 20, where photoresist 21 is applied, is placed inside a baking chamber 18, and is heated with heating plates 1a-1c.
