Lithography photoresist

WebLift off. This process is the general method of removing photoresist after deposition of a film on a wafer patterned by negative lithography. It takes advantage of the height different between the photoresist and the thin film to simply lift away the photo resist while keeping the patterned film intact. Set a hot plate to 200℃.

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 … WebPhotolithography is an important step in the process of creating semiconductor chips. The steps involve exposing a photoresist layer to light, developing it, and etching the pattern onto a mask to transfer when applied on top of metal or glass substrates.
