Abstract: 반도체 웨이퍼 등의 피 에칭체(212)의 표면에 밀리미터 오더의 개구 치수(R)를 갖는 오목부(220)를 형성하기 위한 에칭 방법이다. 이 방법에서는 우선 피 에칭체(212)의 표면에, 오목부(220)에 대응한 개구부분을 갖는 마스크(214)를 형성한다. 다음에, 마스크(214)가 형성된 피 에칭체(212)를 플라즈마 에칭용 처리용기내에 배치하고, 처리용기내에서 플라즈마을 이용하여 에칭한다. 본 발명에서는 마스크(214)의 재료로서, 피 에칭체(212)와 동일한 재료, 예컨대 실리콘(Si)을 사용한다. 이것에 의해서, 상기한 바와 같은 오목부(220)를 실질적으로 바닥면(222)에 서브 트렌치 형상(주연부가 중앙부보다 깊게 에칭된 형상)이 발생하지 않도록 형성할 수 있다.

Abstract: Provided is a method of etching a multilayer film including an organic film formed between first and second oxide films. In this method, a high frequency power for generating plasma in etching the organic film is greater than those in etching the first and second oxide films. High frequency bias powers for ion implantation in the etching of the first and second oxide films are greater than that in the etching of the organic film. In the etching of the first and second oxide films and the organic film, a magnetic field is generated such that horizontal magnetic field components in a radial direction with respect to a central axis line of a target object have an intensity distribution having a peak value at a position far from the central axis line, and a position of the peak value in the etching of the organic film is closer to the central axis line than those of the horizontal magnetic field components of the first and second oxide films.

Abstract: An etching method for forming a recess (220) having an opening dimension (R) of millimeter order in an object (212) to be etched such as a semiconductor wafer. A mask (214) having an opening corresponding to the recess (220) is formed on the object (212). The object (212) with the mask (214) is placed in a processing vessel for plasma etching and etched in it using a plasma. The material of the portion around the opening of the mask (214) is the same as the material, for example, silicon of the object (212). Hence, the recess (220) can be so formed as not to form a sub-trench shape (a shape formed by etching the periphery of which is deeper than the center) substantially in the bottom (222).
