发明名称 Scanning wedge method for determining characteristics of a photoresist
摘要 A method and a system for determining the characteristics of a photoresist are disclosed. This scanning wedge method is accomplished by linearly varying the exposure dose the photoresist receives. Thereafter, the photoresist is developed. The location of interference fringes on the developed photoresist is then determined. This provides the data necessary to determine the characteristics of the photoresist.
