WebLithography is the heart of the semiconductor fabrication process. It is used to pattern specific shapes of a thin layer on a rigid substrate for fabricating electrical … WebThe printed circuit board (PCB) industry has long used a lithography process based on a polymer mask in contact with a large, resist-coated substrate. There is a limit to this technique since both the masks and PCB substrates themselves may undergo distortion during fabrication, making high resolution or tight registration difficult.

WebLithography applications require motion stage calibration to ensure repeatability in the positioning of many different stages in the fab. MKS offers a series of high-performance air bearing stage solutions suitable for use in semiconductor photolithography applications and customized tools for automated manufacturing and process control. 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… flory vx240
