Abstract:
PURPOSE: A ribbon cable coupling apparatus is provided to prevent a cable from being down by suppressing fatigue of the ribbon cable when a moving board is moved. CONSTITUTION: A ribbon cable coupling apparatus includes a moving board(21) and a stationary board(23). A ribbon cable(29) is coupled to both ends of the ribbon cable pins(25). The ribbon cable pins(25) are supported by guides(27). The ribbon cable pins(25) and the guides(27) are coupled to the moving and stationary boards(21,23). Each end portion of the guides(27) is extended and rounded so as to prevent fatigue of the ribbon cable(29) when the moving board is moved.
Abstract:
A process apparatus for fabricating a semiconductor device is provided to prevent or minimize a process error and a notch decision error by installing a filtering unit at an orienter. A process apparatus(200) for fabricating a semiconductor device includes a substrate transfer module(210), an orienter(220), and a filtering unit. The substrate transfer module is formed to transfer a semiconductor substrate. The orienter is formed to determine a notch of a wafer. The filtering unit is installed at the orienter. The filtering unit changes a flow rate to apply external air of the orienter to the substrate transfer module. The filtering unit is formed with a fan filter unit(222) which is attached on the orienter. The process apparatus corresponds to an etch apparatus.

Abstract:
본 발명은 플라즈마를 이용한 건식 식각 공정시 챔버로부터 방사되는 플라즈마 파장 변화를 통해 웨이퍼 전면 상부에 증착되어 있는 물질막에 대해 식각종말점을 검출하는 식각종말점 검출장치에 관한 것이다. 본 발명에서는, 공정 챔버로부터 방사되는 플라즈마 파장이 일차적으로 통과하는 쿼르츠와, 상기 쿼르츠를 통과한 플라즈마 파장을 후방의 파장 검출부로 전달하는 중간역할을 하는 전달매체(광케이블)를 일정 간격 이격시켜 형성한다. 그 결과, 상기 쿼르츠와 전달매체간의 마찰로 인한 마모가 감소되어 상기 쿼르츠부의 탁해짐 현상 및 스크래치 현상이 방지되어 보다 정확한 식각종말점 검출이 가능해진다. 또한, 쿼르츠부 및 전달매체의 수명이 연장되어 전체 생산비를 절감할 수 있게 된다.
