发明名称 RETICLE STRUCTURE WITH HOLE PATTERN FOR PREVENTING GHOST IMAGE
摘要 <p>A reticle for forming a microscopic pattern is formed that prevents a ghost image generated in a photolithography process for patterning microscopic-sized holes. The reticle may include a quartz substrate; a first pattern formed by exposing a portion of the surface of the quartz substrate; a second pattern surrounding the first pattern and including a phase shift layer; and a third pattern including an opaque layer around the second pattern.</p>
