Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 半導体ウェハ上にプロセス裕度及び補正精度 が高いパターンを形成するマスクパターン補正方法を提 供する。 【解決手段】 所定のデザインルールに従って設計され た、半導体装置の光露光工程において使用するマスクの 設計パターンから、露光量と焦点距離の変動に対するプ ロセス裕度が所定の基準値に達していないパターンを抽 出する第1ステップと、プロセス裕度が基準値を満たす ようにパターンを補正する第2ステップとを少なくとも 具備する。デザインルール上では製造可能であるが、光 露光工程での露光量、焦点距離の変動によるパターン寸 法の変動量が大きくなるパターンに対して、そのプロセ ス裕度を高めることができる。 (57) [Problem] To provide a mask pattern correction method for forming a pattern with high process latitude and correction accuracy on a semiconductor wafer. SOLUTION: From a design pattern of a mask used in a light exposure process of a semiconductor device, which is designed according to a predetermined design rule, a pattern in which a process margin with respect to a variation in an exposure amount and a focal length does not reach a predetermined reference value. The method includes at least a first step of extracting and a second step of correcting a pattern so that a process margin satisfies a reference value. Although it can be manufactured according to the design rules, it is possible to increase the process margin for a pattern in which the amount of change in the pattern dimension due to the change in the exposure amount and the focal length in the light exposure step becomes large.
