Title: An image reversal technique for forming small structures in integrated circuits
Inventor: STOLMEIJER ANDRE
IPC: H01L21/28
Filed: 1997-02-04
Abstract: PURPOSE: A method is improved to fabricate small structures including contacts, vias, and metal lines to be employed in integrated circuits. CONSTITUTION: An image reversal technique to obtain improved feature definition is employed. In forming a feature in a layer of material, a clear field reticle is used to form patterned segments of photoresist each having a size, a shape, and a location substantially identical to the size, the shape, and the location of one of the features intended to be formed in the layer of material. This method is employed instead of using a dark field reticle which forms windows in a photoresist each having a size, a shape, and a location substantially identical to the size, the shape, and the location of one of the features intended to be formed in the layer of material. For small structures, the openings or windows in a photoresist are harder to form than the patterned segments of photoresist. With the method of employing a clear field reticle to form a mask comprising patterned segments of photoresist, the limitations of patterning small windows in a photoresist with the use of a dark field reticle are avoided.

Abstract: 본 발명은 서류펀치용 펀칭 핀의 가공방법에 관한 것이다. 
     종래의 방법으로는 일단 봉상의 와이어 소재를 소정의 길이로 절단 한 다음 하단 부를 컷팅기에 의하여 작업자가 일일이 컷팅작업을 실시하게 됨으로서 절취량 만큼씩의 재료 손실이 발생되고 작업자에 의하여 가공하기 때문에 인력낭비가 클 뿐아니라 생산성이 저하되고 일률적인 균일 가공이 불가능하여 불량률이 많이 발생되는 문제점이 있었다. 
     본 발명은 소정의 길이로 절단된 소재를 금형에 의하여 먼저 "V"자형 홈을 형성할 면에 소정의 깊이로 가압하여 홈을 형성하게 되면 금형 내의 소재는 일정 체적 안에서 팽창하여 늘어나게 됨으로 재료의 손실을 막을 수 있으며, 이후 "V"자형 홈을 가공하기 위한 날이 선단에 대응되게 형성된 펀치로써 홈이 형성된 소재를 다시 한번 가압하여 눌러 "V"자 홈을 형성하게 될때 무리없이 "V"자형 홈을 형성하게 되는 것으로 일체의 재료 손실없이 무인 자동화 생산이 가능하여 원가절감은 물론 품질 향상과 생산성 증대에 크게 기여할 수 있게 되는 것이다.
