Litho stepper
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… WebTo achieve that kind of overlay, a lithography system needs to know the position of a wafer to within fractions of a nanometer before it exposes the pattern. When it enters the system, the wafer is initially positioned with a precision of around 80 micrometers – about the diameter of an average human hair. But that isn’t nearly accurate enough.
