摘要:
A method for fabricating a mask (or reticle) to improve the mask ESD immunity is provided. A substrate having an upper surface is substantially transparent to a selected radiation. A light sensitive layer is formed over the substrate. The light sensitive layer is patterned and etched to form a pattern of openings in the light sensitive layer. The substrate is etched according to the pattern of openings in the light sensitive layer. The light sensitive layer is stripped. An opaque layer is then deposited on the upper surface and in the openings of the patterned substrate. The substrate is planarized by removing excess opaque layer from over the upper surface of the substrate. A pellicle is then mounted outstretched on the upper surface of the substrate.
摘要(中):
提供了制造掩模(或掩模版)以提高掩模ESD抗扰度的方法。 具有上表面的基底对所选择的辐射基本上是透明的。 在衬底上形成光敏层。 对感光层进行图案化和蚀刻,以在光敏层中形成开口图案。 根据光敏层中的开口图案蚀刻衬底。 剥去光敏层。 然后在图案化衬底的上表面和开口中沉积不透明层。 通过从衬底的上表面上去除多余的不透明层来平坦化衬底。 然后将防护薄膜组件伸出到衬底的上表面上。
