Photolithography processing
WebPhotolithography is the process used to transfer patterns of geometric shapes to a flat substrate. The substrates are first coated with a material called resist, then light (called optical photolithography) is used to catalyze reactions in the resist to create the shape of the pattern. The resist is then developed to separate the un-reacted and reacted portions, … WebExperienced process and NPI engineer with demonstrated history of working within the semiconductor industry.
