Web1.1 Introduction to Optical Lithography As critical dimensions(CD’s, also called “feature size”) in the rapid development of the semiconductor industry have been continuously reduced, the improvement of optical lithography has played a very important role in the semiconductor industry. Lithographic requirements differ from chip to chip. Web25 jun. 2024 · The stochastic impact will manifest itself as defocus variation, i.e., how far the wafer location is from best focus, as well as CD variation (see Figure 3). Figure 3.
