Title: Manufacturing method for semiconductor device
Inventor: JANG HEON YONG
IPC: H01L21/28
Filed: 2000-06-29
Abstract: PURPOSE: A method for manufacturing a semiconductor device is provided to prevent a bridge between a bitline and a gate electrode, by preventing a loss of a mask insulation layer pattern on a gate electrode in an etch process for forming a bitline contact hole. CONSTITUTION: A gate insulation layer, a conductive layer for the gate electrode(16) and a mask insulation layer are stacked on a semiconductor substrate(10). The stacked structure is etched to form a stacked structure pattern of a mask insulation layer pattern(22), the gate electrode and a gate insulation layer pattern(14). An insulation layer spacer(24) is formed on the sidewall of the stacked structure, and impurity ions are implanted into the substrate at both sides of the insulation layer spacer to form a junction region. A conductive layer is formed. A contact plug(26) coupled to the junction region is formed by a chemical mechanical polishing(CMP) process, and the mask insulation layer pattern is lost in the CMP process so that a step between the contact plug and the mask insulation layer pattern is generated. A nitride layer(28) having etch selectivity regarding the mask insulation layer pattern is formed to compensate for the lost mask insulation layer pattern. An oxide layer(30) is formed on the nitride layer. The oxide layer and the nitride layer are removed to form a bitline contact hole by an etch process using a bitline contact mask as an etch mask. A bitline(36) coupled to the contact plug is formed through the bitline contact hole.

Abstract: 본 발명은 냉동사이클용 3방향 냉매조절밸브에 관한 것으로, 그 목적은 병렬로 배치된 열교환기에 동시 또는 선택적으로 냉매 공급을 제어할 수 있도록 하는 것이다. 
     본 발명에 따른 냉동사이클용 3방향 냉매조절밸브(40)(400)에 의하면, 두 개의 오리피스(42A,421)(43A,431)를 동시에 개방하거나 어느 하나의 것만을 개방할 수 있도록 구성되어 있어서, 병렬로 배치된 제1증발기(11)와 제2증발기(12)에 동시 또는 어느 하나에만 선택적으로 냉매패스 조절이 가능하다.  이에 따라 독립적인 냉각실(R1)(R2) 제어가 요구되는 냉동사이클 적용제품에 3방향 냉매조절밸브(40)(400)를 보다 용이하게 구성할 수 있으며 아울러 냉동사이클의 전체적인 구성부품수가 줄어 제조비용을 절감된다.  또한, 오리피스(42A,421)(43A,431) 개폐작동이 회전자(46B,462)의 회전운동에 따라 점진적으로 수행되기 때문에 개폐 작동에 따른 운전소음이 발생되지 않는다.  또한, 2개의 의 오리피스(42A,421)(43A,431) 중 적어도 어느 하나는 항상 개방된 상태를 유지함으로써, 압축기(20) 운전이 중지되어도 압력차에 의해 냉매가 흐르게 된다. 이에 따라 압축기(20) 오프 시 입구측과 출구측 걸리는 양단의 압력차이가 거의 없기 때문에, 압축기(20) 재구동 시 압력차이에 의한 기동불량을 최소화 할 수 있는 이점이 있다.
