Litho wafer
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 WebSteegen described DSA as a complimentary litho technique that is having quite some momentum. The process starts with a “relaxed” guiding pattern on your wafer. Then, depending on the polymer length in the block copolymer, the space in between the guiding structure is replicated into multiple lines and spaces.
