What is photo resist used to make?

Answer 1

Photoresist is a light-sensitive material used primarily in photolithography processes to create patterns on semiconductor wafers during the manufacturing of integrated circuits. When exposed to light, photoresist undergoes a chemical change, allowing selective removal of either the exposed or unexposed areas, depending on whether it is a positive or negative photoresist. This enables the precise transfer of circuit designs onto the wafer surface, facilitating the production of microelectronics and various other applications in Nanotechnology and microfabrication.
