Title: Method and apparatus for injection molding
Inventor: MATHEW EMMETT SAYER
IPC: B29C45/34
Filed: 1988-09-24
Granted: 1996-11-07
Abstract: An injection moulded plastics article is produced by introducing a stream of molten plastics material from an injection moulding machine cylinder into an article forming mould space (13). Pressurised gas is supplied into the interior of the molten plastics material to form a gas containing cavity (25) therein. The plastics material is then allowed to solidify and cool sufficiently so that the article can itself sustain the form dictated by the mould surface. The cavity is vented to reduce the pressure within the cavity to ambient pressure prior to opening of the mould. The step of venting the cavity is achieved by providing at at least one position which is separate from the plastics inlet and the gas inlet a vent passage (30) in the mould open at its inner end to a part of the interior of the mould at which the gas containing cavity (25) is formed, and a retractable closure (31) for opening and closing the vent passage at its inner end, maintaining the closure in its closed position during the forming of the article whereby the cavity wall is formed over the inner end of the vent passage and the closure therefor, and subsequently retracting the closure to allow the creation of a vent opening in the cavity wall in the area of the inner end of the vent passage through which vent opening gas from the cavity passes into the vent passage. Apparatus for carrying out the above process is also described.

     본 발명은 래터럴형 바이폴라 트랜지스터의 제법에 있어서, 제1 도전형의 베이스 영역이 되는 반도체 기판에, 한쌍의 개구를 갖는 제1 마스크를 개재하여 횡측 방향을 따라서 제2 도전형의 콜레터 영역 및 에미터 영역을 형성하는 공정과 제1 마스크의 개구 간격보다 넓은 개구 간격을 갖는 제2 마스크를 개재하여 각각 상기 콜렉터 영역 및 에미터 영역에 접속하는 제2 도전형의 고농도 영역을 형성하는 공정을 가짐으로써 베이스폭 W B 의 단소화를 가능하게 하고, 고 f T . 고 h FE 화를 꾀하도록 한 것이다. 
     또한. 본 발명은 공통의 반도체 기판에 래터럴형 바이폴라 트랜지스터, 버티컬형 바이폴라 트랜지스터 및 가드 링을 가진 쇼트키 배리어 다이오드로 이루어지는 반도체 장치의 제법에 있서서, 공통의 마스크에 동시에 형성된 각 개구를 통하여 동일의 불순물을 도입하여 래터럴형 트랜지스터의 에미터 영역 및 콜렉터 영역, 쇼트키 배리어 다이오드의 가드 링 영역과 버틸컬형 트랜지스터의 링크 베이스 영역을 동시에 형성함으로써 성능을 나빠지게 함이 없이 공정수의 삭감을 도모한 것이다.
