hello everyone
1.Why do we mask the silicon wafer and distinguish the chip into exposed layer and unexposed layer?
2.what is photolithography?
(It uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical "photoresist", or simply "resist," on the substrate)
couldnt understand this line.
thank you
