OPC has been acknowledged essential technique to achieve low k1 lithography applying any optical process or even if phase-shift controlling. Since several years ago some aspect of OPC technique has been realized with OPC oriented tools, applied to actual design, and many success stories are reported. However according to semiconductor design scale itself is growing as millions of transistors a year as the rule decreasing, so called aggressive OPC is forcing not only data handling distress but also reticle fabrication difficulty even though the hardware's progressing. In this paper, we introduce the evaluation of the performance and the effect from weak to aggressive OPC that has been proposed. Then we will discuss the improved OPC applying modeling and criteria based on the trade off between OPC data handling efficiency and the effect.
