inner machine for photoresist coating

Ultraviolet Wikipedia

Ultraviolet Wikipedia

Ultraviolet radiation is used for very fine resolution photolithography, a procedure wherein a chemical called a photoresist is exposed to UV radiation that has passed through a mask. The exposure causes chemical reactions to occur in the photoresist.
