WebFabrication of an entire layer often entails processing the wafer through lithography before it undergoes subsequent operations in other modules such as etch, implant, etc. The steps in the semiconductor lithographic process are outlined in Fig. 11.1 and illustrated in Fig. 11.2 for a negative and a positive resist.
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… how much is jonathan scott worthWebLithography includes a series of fabrication techniques that share the principle of transferring an image from a mask to a receiving substrate.
