Wafer Lithography
Wafer Lithography Wafer Lithography - Polyimide Coatings - Photoresist Coating - Cheersonic Lithography is the "printing" of a circuit pattern onto a wafer by light, which we can understand as drawing the plan on the surface of the wafer required for semiconductor fabrication. The higher the fineness of the circuit pattern, the higher the integration of the finished chip, which must be achieved through advanced lithography technology. Specifically, photolithography can [...]
