Lithography in wafer fabrication
WebLithography is used to transfer a pattern from a photomask to the surface of the wafer. For example the gate area of a MOS transistor is defined by a specific pattern. The pattern … WebThree different kinds of imprinting lithography techniques UV curing imprinting, thermally curing imprinting with monomer resin, and hot embossing imprinting with polymer resin were used to transfer as small as 70nm patterns of template onto the various substrates including Si wafer, oxidized Si wafer, quartz wafer, glass plate, PET (Polyethylene Terephthalate) …

Web2 jan. 2024 · That's a highly oversimplified version of semiconductor lithography. Here's a video of spin on a layer of photoresist. This is being done manually on a 4" wafer, but this way you can see what is going on. In a modern fab, this is done in a completely automated flow on a 12" wafer. Web2.5.2 Lithography. Micro-lithography is the process of defining useful shapes on the surface of a semiconductor wafer. Typically this consists of a patterned exposure into some sort of photosensitive material already deposited on the wafer. A variety of processes that directly pattern the wafer are possible, such as directly writing on the ...
