PURPOSE: A method for forming a contact pad having improved profile is provided to increase an overlap margin both of the contact pad and an isolating layer and reduce a mis align margin of contacts by using a slope etching. CONSTITUTION: A storage electrode contact pad(110) and a bit line contact pad are simultaneously formed by etching a conductive layer. The contact pads(110) are electrically connected to an active region of a semiconductor substrate(100). Using a slope etching the contact pads(110), the lower width of the etched profile of the contact pads is relatively wider than that of the upper width of the etched profile of the contact pads.

본 발명은 플라즈마를 이용한 반도체 웨이퍼의 감광막 제거 장치에 관한 것이다. 플라즈마를 이용한 감광막 제거 장치는, 웨이퍼를 반응실에 넣고 고주파를 인가한 상태로 산소 기체를 주입하여, 반응실 내부에 생성되는 플라즈마의 높은 에너지를 이용하여 웨이퍼의 감광막을 산화시켜 제거한다. 종래의 감광막 제거 장치는 반응실을 지지하기 위하여 반응실과 결합되어 있는 알루미늄 플랜지에 플라즈마의 영향에 의한 불순물 입자가 발생되어 웨이퍼에 불량을 야기할 수 있다. 따라서 본 발명은 플라즈마 반응실 내부로 노출되는 플랜지의 면에 세라믹 방호 링이 장착된 감광막 제거 장치를 제공한다. 세라믹 방호 링에 의하여 알루미늄 플랜지는 플라즈마의 영향으로부터 보호되며 불순물 입자의 발생이 방지된다. 따라서 반도체 웨이퍼의 수율이 향상되며, 감광막 제거 장치의 신뢰도 및 공정의 생산성이 향상된다.

Abstract:
An apparatus for sawing a wafer is provided to perform simultaneously a sawing process on plural wafers by installing plural transfer members and plural chuck tables in a work space. A wafer loading/unloading unit(110) has a wafer cassette(115). Plural wafers to be sawed or been sawed are mounted on the wafer cassette. Plural transfer members(125) transfer the wafer mounted on the wafer cassette to a work place where a sawing process is performed. Plural chuck tables(135) are installed in the work place. A real wafer sawing process is performed at the chuck tables. The number of the transfer members and the chuck tables are the same. The number of the transfer members and the chuck tables are respectively four. The transfer members are arranged as height difference as an interval between wafers in the wafer cassette.
