Lithography photoresist
WebFirst, the substrate is coated with a photoresist: a thin, flat layer of a light-sensitive substance. Next, the photoresist is exposed to a precise pattern of intense (typically ultraviolet) light. This is typically achieved using a “photomask” which blocks some parts of the light, while letting through others, although in some applications, the pattern is … WebNegative photoresists for optical lithography. Abstract: Negative photoresists are materials that become insoluble in developing solutions when exposed to optical radiation. They were the first systems used to pattern semiconductor devices, and still comprise …
