RETICLE, SYSTEM COMPRISING A PLURALITY OF RETICLES AND METHOD FOR THE FORMATION THEREOF
Abstract:
A method includes providing a pre-optical proximity correction (OPC) layout of at least a portion of at least one reticle. The pre-OPC layout defines a test cell including a first test cell area having a plurality of first target features having a first pitch and a second test cell area having a plurality of second target features having a second pitch. A post-OPC layout of the portion of the reticle is formed on the basis of the pre-OPC layout. The formation of the post-OPC layout includes performing a rule-based OPC process, wherein a plurality of first reticle features for the first test cell area are provided on the basis of the plurality of first target features, and performing a model-based OPC process, wherein a plurality of second reticle features for the second test cell area are provided on the basis of the plurality of second target features.
