Abstract: 플라즈마에칭방법은제 1 공정과제 2 공정을포함한다. 제 1 공정은, 처리챔버의내부에수용된기판에형성된피처리막을에칭하는에칭처리를실행함으로써피처리막에홀을형성한다. 제 2 공정은, 제거공정과퇴적공정과깊게에칭하는연장공정을반복실행한다. 제거공정은, 에칭처리를실행함으로써형성된홀의입구부에부착된반응생성물을제거한다. 퇴적공정은, 제거공정에의해반응생성물이제거된홀의측벽부에퇴적물을퇴적시킨다. 연장공정은, 퇴적공정에의해퇴적물이측벽부에퇴적된홀을, 에칭처리를진행시킴으로써깊게에칭한다.
Abstract translation: 等离子体蚀刻方法包括第一工序和第二工序。 在第一工序中,通过进行蚀刻处理对象膜的蚀刻工序,在容纳在处理室内的基板上形成的处理对象膜中形成有孔。 在第二过程中,重复执行去除处理,沉积处理和延伸处理。 在去除过程中,去除附着在通过蚀刻工艺形成的孔的入口部分的反应产物。 在沉积过程中,沉积物沉积在孔的侧壁上,通过去除过程从中除去反应产物。 在延伸过程中,通过沉积工艺沉积在其侧壁上的孔通过进行蚀刻工艺被深刻蚀刻。

Abstract: PURPOSE: Plasma processing ring-shaped components and a plasma processing apparatus are provided to improve the yield of a plasma processing process by regulating the distribution of electric field on the main surface of a wafer. CONSTITUTION: An electrostatic chuck(16) functions as a heat exchanging plate by being in connection with a wafer(15). The heat exchanging plate regulates the temperature of the wafer. A focus ring(5), which is one of plasma processing ring-shaped components, is arranged on the external side of the wafer. A ring-shaped exhaust duct(6) is formed between the sidewall of a processing chamber and a cylindrical supporting part.

Abstract: PURPOSE: An etching device and a method for supplying etching gas are provided to stably control gas flow rate by controlling hunting of the gas flow rate generating when gas is changed. CONSTITUTION: First etching gas which is used for an etching process is provided within a treatment basin. Second etching gas used for the etching process is provided within the treatment basin. The flow rate of the second etching gas and the first etching gas is controlled by a gas flow rate control device. The change of the second etching gas and the first etching gas is processed by turns. A gas supply source supplies the second etching gas and the first etching gas to the treatment basin.
