WebOffset lithography printing, given the multitude of material choices, produces more frequent print defects relating to non-conforming materials. The International Standards Organization has developed several standards to define the quality of graphic images, based on various perspectives such as tone, colour, resolution, contrast, etc. WebThis leads to immersion-related defects, of which the major types are bubble and `anti-bubble’ types, as well as water marks, particles, and microbridges.2–4 These are observed on almost all 193nm immersion-processed wafers and account for more than 90% of the total defects. This article describes these bubble and anti-bubble defects ... WebThe key concerns for nanoimprint lithography are overlay, defects, template patterning and template wear. However, recently Kumar et al. have shown that amorphous metals (metallic glasses) can be patterned on sub-100 nm scale, which can significantly reduce the template cost. Overlay.
