Coating photoresist
Web1. A computer-implemented method of determining a dose-to-clear of a photoresist on a wafer, wherein the dose-to-clear is the amount of energy to which the photoresist must be exposed in order to dissolve the entire exposed area of the photoresist when the photoresist is developed, the method comprising: providing an image of the wafer after …

WebFor spray coating, since the photoresist droplets are supposed to stay where they are deposited, the amount of SU-8 wasted during spray coating can be significantly less than with spin coating. Furthermore, an interesting advantage of spray coating is that it can be used on non-flat or textured wafers (e.g., wafers with holes, striations, etc.). WebSpin coating is a widespread practice in modern scienceand engineering, where it is used to deposit uniform coatings of organicmaterials and/or to uniformly distribute particulate matter on a flatsurface.
