Photolithographic process
Webphotolithographic process, characterization is necessary to establish the op timum operating parameters. As the entire wafer is subjected to each exposure, creative methods must be used to perform dose testing efficiently. Typical examples utilize a wafer-sized cover with a section cut out, similar to a pie missing one piece. WebThe meaning of PHOTOLITHOGRAPHY is lithography in which photographically prepared …
