摘要: A method for performing a photolithography process includes providing a reticle on a projection apparatus, the reticle having a test pattern defined thereon, the test pattern including a plurality of one-dimensional structures and a plurality of two-dimensional structures. The test pattern defined on the reticle is transferred to at least one area on a wafer. The projection apparatus is focused on the test pattern transferred on the wafer during a photolithography process to perform a process monitoring.
