What it is
How it works
General reference — not yet source-verifiedProjection lithography systems position a mask in the optical path between an illumination source and a substrate. The mask image is projected through imaging optics onto the substrate, which is coated with a photosensitive resist. The pattern is formed on the resist as a latent image when the resist is exposed to the projected light.
Before exposure, the system aligns the mask to features already present on the substrate. Alignment is carried out by detecting alignment marks on the wafer and adjusting the stage position so that the new pattern overlays previous layers correctly. The exposure cycle then continues field by field across the substrate.
Where it fits in the process flow
General reference — not yet source-verifiedPhotolithography is the patterning operation at the heart of semiconductor device fabrication. In the process flow, wafers are cleaned, coated with photosensitive resist, and then aligned and exposed on a lithography tool. After exposure, wafers are developed to leave a resist pattern in place of the latent image.
