Lithography medical
In integrated circuit manufacturing, photolithography or optical lithography is a general term used for techniques that use light to produce minutely patterned thin films of suitable materials over a substrate, such as a silicon wafer, to protect selected areas of it during subsequent etching, deposition, or implantation operations. Typically, ultraviolet light is used to transfer a geometric design from an optical mask to a light-sensitive chemical (photoresist) coated on the substrate. T… 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 …

The electron beam exposes the pattern and then the resist can be developed.
WebThe lithography process is the most critical step in the manufacturing process. Lithography determines the critical dimensions of the chip and accounts for about 35% of the overall manufacturing cost in the entire chip manufacturing process. WebSince lithography for device fabrication involves the use of optical exposure to create the pattern, semiconductor lithography is commonly called "photolithography". As with the …
