Photolithography mask design
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 … Optical proximity correction (OPC) is a photolithography enhancement technique commonly used to compensate for image errors due to diffraction or process effects. The need for OPC is seen mainly in the making of semiconductor devices and is due to the limitations of light to maintain the edge placement integrity of the original design, after processing, into the etched image on the s…

WebPhotolithography is a patterning process in which a photosensitive polymer is selectively exposed to light through a mask, leaving a latent image in the polymer that can then be selectively dissolved to provide patterned access to an underlying substrate. From: Nanocoatings and Ultra-Thin Films, 2011 View all Topics Add to Mendeley About this page WebDaLI — a tabletop maskless lithography system DaLI is a universal table-top system for maskless lithography with all standard photoresists. Its comprehensive software solution covers all steps from design to illumination and makes DaLI an intuitive solution regardless of users’ prior knowledge.
