photoresist

Photoresist is a special light-sensitive material used in manufacturing electronic components like computer chips. It is applied as a thin film onto a microscopic surface. When exposed to specific light patterns, the photoresist undergoes chemical changes, allowing certain areas to be washed away or hardened. This process enables precise shaping and patterning of tiny structures on silicon wafers, which are then used to create complex electronic circuits. Essentially, photoresist acts as a mask, guiding the construction of intricate microelectronic devices with high accuracy.
