Web25 feb. 2024 · One evident need is double-side alignment of different layers, calling for special lithography equipment. However, it should also be stressed that when one side of a wafer is treated, the other one should be protected from accidental damage (e.g., scratches) caused by the contact to the processing tools, which are typically not made for double … WebAlignment: Integrated circuits are fabricated by a series of patterning steps. These start with a lithography operation followed by an etch or ion implantation. Between patterning …

Web20 jul. 2015 · The method comprises the following steps: (1) depositing a dielectric film on the surface of a silicon substrate, and etching the lithography alignment mark, wherein … Exposure systems typically produce an image on the wafer using a photomask. The photomask blocks light in some areas and lets it pass in others. (Maskless lithography projects a precise beam directly onto the wafer without using a mask, but it is not widely used in commercial processes.) Exposure systems may be classified by the optics that transfer the image from the mask to the wafer.
