Development photolithography
WebPhotolithography shares some fundamental principles with photography in that the pattern in the etching resist is created by exposing it to light, either directly (without using a mask) or with a projected image using an optical mask. ... The development of low-defectivity anisotropic dry-etch process has enabled the ever-smaller features ... WebDevelopment is the dissolution of unpolymerized resist that transforms the latent resist image, formed during exposure, into a relief image that will serve as a mask for further …
