WebLithography definition: A printing process in which the image to be printed is rendered on a flat surface, as on sheet zinc or aluminum, and treated to retain ink while the nonimage areas are treated to repel ink. WebIntroduction. Photomasks used for optical lithography contain the pattern of the integrated circuits. The basis is a so called blank: a glass substrate which is coated with a chrome and a resist layer. The resist is sensitive to electron beams and can be transferred into the chrome layer via etch processes. The chrome represents opaque areas on ...

Other technologies in this broader class include the use of steerable electron beams, or more rarely, nanoimprinting, interference, magnetic fields, or scanning probes. On a broader level, it may … See more 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 See more Exposure systems typically produce an image on the wafer using a photomask. The photomask blocks light in some areas and lets it pass in others. (Maskless lithography projects a precise beam directly onto the wafer without using a mask, but it is not … See more The ability to project a clear image of a small feature onto the wafer is limited by the wavelength of the light that is used, and the ability of the reduction lens system to capture enough diffraction orders from the illuminated mask.
