Litho-Etch-Litho-Etch 로 2회 노광을 필요로 하는 LELE 기법은 하나의 Layer를 2개의 Mask를 사용해서 패턴을 만들어주는 기법을 의미한다. WebSADP manufacturing process comes with lots of challenges. Several approaches were introduced to manufacture SADP. The most major SADP manufacturing approach is the Spacer-Is-Dielectric (SID). One of the main advantages of SADP over Litho-Etch-Litho-Etch (LELE) Double Patterning (DP) is better Mask Overlay Control.

Multiple patterning (or multi-patterning) is a class of technologies for manufacturing integrated circuits (ICs), developed for photolithography to enhance the feature density. It is expected to be necessary for the 10 nm and 7 nm node semiconductor processes and beyond. The premise is that a single … Meer weergeven There are a number of situations which lead to multiple patterning being required. Sub-resolution pitch The most obvious case requiring multiple patterning is when the feature pitch is below the … Meer weergeven In spacer patterning, a spacer is a film layer formed on the sidewall of a pre-patterned feature. A spacer is formed by deposition or reaction of the film on the previous pattern, followed by etching to remove all the film material on the horizontal … Meer weergeven In self-aligned double patterning (SADP), the number of cut/block masks may be reduced or even eliminated in dense patches … Meer weergeven The earliest implementation of multiple patterning involved line cutting. This first occurred for Intel's 45nm node, for 160 nm gate pitch. … Meer weergeven The earliest form of multiple patterning involved simply dividing a pattern into two or three parts, each of which may be processed conventionally, with the entire pattern … Meer weergeven Self-aligned contact and via patterning is an established method for patterning multiple contacts or vias from a single lithographic feature.
