Lithography control
WebAlternatively, tight control loops for controlling a stability of the lithographic apparatus may be used to improve reproduction of the pattern at low kl. [0006] In lithographic processes, it is desirable to make frequently measurements of the structures created, e.g., for process control and verification. WebAbstract: Lithography is a word with two distinct definitions. If you Google "lithography", 7 of the first 10 hits will refer you to the art world and a process invented by Aloys Senefelder in 1788 (1). A short description of the process from the Merriam-Webster Online Dictionary defines it as "the process of printing from a plane surface (as a ...
