WebLithography & Wafer Inspection Components. Resistant to chemical attack and thermally stable, our high-purity ceramic components are ideal for lithography processing, wafer handling (low contamination), and wafer inspection (extreme durability and hardness, dimensionally stable). Applications include: WebSteegen described DSA as a complimentary litho technique that is having quite some momentum. The process starts with a “relaxed” guiding pattern on your wafer. Then, depending on the polymer length in the block copolymer, the space in between the guiding structure is replicated into multiple lines and spaces. 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. dick hudsons baildon

WebLithographers often refer to monochromatic exposure systems as "i-line", "g-line", DUV etc. as opposed to specifying the actual wavelength emitted. Systems with broad spectrum lamps or "broadband" systems typically emit wavelengths that span roughly the 350nm to 450nm wavelength range (or some subset of this range).
