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 process employed in IC fabrication. As shown in Figure 5.1(b), the radiation is WebFor NCM lithography, the needle tip is brought close to the silicon surface. An external voltage pulse is applied between the needle tip and the silicon substrate such that the needle tip is negatively charged with respect to the silicon substrate. The cantilever is then excited at its resonance frequency (300kHz), similar to ICM operation.
Web2 sep. 2024 · The exposed multilayer reflective film reflects EUV light. In EUV lithography, a light image reflected by a multilayer reflective film (a portion where an absorber pattern does not exist) is transferred onto a semiconductor substrate (transfer target) such as a silicon wafer through a reflective optical system.
