WebWhat is lithography in VLSI? Lithography is the process of transferring patterns of geometric shapes in a mask to a thin layer of radiation-sensitive material (called resist) covering the surface of a semiconductor wafer. How Nanosensor would Works? Nanosensors typically work by monitoring electrical changes in the sensor materials. WebThe photolithography used in microcircuit fabrication sequences, also called lithography and microlithography, is an image formation and transfer process, which evolved from that used in the printing industry for about 200 years. The word lithography actually means “writing on or with a stone.”.
