Lithography diagram

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. Web2 sep. 2024 · Developed since the early 1980s, the FIB technology was initially aimed at the semiconductor industry, where it has been extensively employed for failure analysis, circuit debugging, device modification, and lithographic mask repair [29–33].However, since the 1990s the FIB instrument has also become a popular machining tool in other fields such …
