Lithography lighting
WebUnderstanding light in photography depends on where the photographer places the light source, be it natural or artificial. And doing this affects the final image more than anything. Putting the light in front of the subject … WebIn immersion lithography, light travels down through a system of lenses and then a pool of water before reaching the photoresist on top of the wafer. Immersion 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 …
