Lithography cd
Web1 INTRODUCTION. IC fabrication in the current technology nodes of 14 nm, is a complex elaborate process which has evolved through many decades. Conventional immersion lithography uses a laser beam of 193 nm wavelength to print the layout features.However, printing sub-20 nm features without distortion is a major challenge due to the huge sub … WebCHAPTER 5: Lithography Lithography is the process of transferring patterns of geometric shapes in a mask to a thin layer of radiation-sensitive material (called resist) covering the surface of a semiconductor wafer. Figure 5.1 illustrates schematically the lithographic …
