Immersion lithography - Wikipedia

WebImmersion lithography is a photolithography resolution enhancement technique for manufacturing integrated circuits (ICs) that replaces the usual air gap between the final lens and the wafer surface with a liquid medium that has a refractive index greater than one. The resolution is increased by a factor equal to the refractive index of the liquid. Web4 jun. 2024 · The lithography machine transmits the light beam through a mask with a circuit diagram through a series of light source energy and shape control methods, and compensates for various optical errors through the objective lens. The circuit diagram is scaled down and then mapped onto the wafer. iroh boots
