    摘要: A method in which in case different kinds of processing are consecutively conducted in a single chamber of a plasma device, a residual portion of a processing gas used in one process is prevented from affecting a next process, is disclosed. A chemical species resulting from the processing gas in one process is prevented from being generated in forming a plasma in the next processing, by introducing an inactive gas after the processing gas used in one processing is exhausted once, or by introducing the inactive gas while exhausting the processing gas, or by cyclically repeating exhaust of the processing gas and introduction of the inactive gas, prior to the next process. The degree of exhaust may be monitored on the basis of an emission spectrum of the plasma. If the exhaust is carried out between a dry etching process conducted while holding a substrate on a single electrode electrostatic chuck and a process of removing residual charge of the chuck in a state of non-bias application to the substrate, or between a just etching process and an over etching process, deterioration of an etching shape due to radicals in the plasma may be prevented.

    摘要: An improved method of manufacturing a semiconductor device includes forming an insulating layer on a substrate, depositing a metal film layer on the insulating layer and depositing a photoresist layer on the metal film layer. The photoresist layer is formed with openings through which a predetermined surface of the metal film layer is exposed. The predetermined surface of the metal film layer is subjected to dry etching so that an underlying portion of the insulating layer is exposed. The remaining portion of the photoresist layer is then subjected to ashing by using an isopropyl alcohol-containing gas to expose the surface of said metal film layer.

    摘要: A method for anisotropic etching of a layer of a silicon-based material, using an SF.sub.6 gas, a versatile etching gas, is proposed. Sulfur (S) is used as a sidewall protection substance. This sulfur is not supplied into an etching reaction system on discharge dissociation of the etching gas, but is supplied by being sublimed off on heating from the inner wall surface of the etching chamber on which it is previously grown from a gaseous phase. Specifically, the S.sub.2 F.sub.2 gas is introduced while a predetermined region of the inner wall surface of the etching chamber is cooled, and preliminary discharge is carried out to deposit sulfur on the region. A SF.sub.6 containing etching gas is introduced into the chamber and the above mentioned region is heated for subliming S and simultaneously etching the layer of the silicon-based material. With this method, there is no necessity of using a specific etching gas capable of yielding free S in the plasma under discharge dissociating conditions. The present invention has an important significance as post-CFC (chlorofluorocarbon) gas measures. After end of etching, sulfur may be easily sublimed off by heating the wafer without the risk of pollution by particles.

    摘要: A dry etching equipment includes a topography simulator and a control section. The topography simulator controls an amount of deposition species incident upon a sidewall to be processed in accordance with a wafer opening ratio and a solid angle of a local pattern, the deposition amount being represented by a product of a reaction product flux and the solid angle. The control section compares a database obtained by the topography simulator with an actual measured value detected from an etching condition during dry etching to calculate a correction value for etching process, and indicates the correction value to an etching chamber in the dry etching equipment. The dry etching equipment corrects in real time a parameter for the etching process conducted in the etching chamber.
