Small field lithography
Webb2.4.3.1 Contact Mode Lithography. When LON is performed using AFM in contact mode, a small tip load is required, with a bias voltage variation of approximately 5 to 20V, and a typical tip speed from 0.1 to 10m/s [ 212 ]. The applied force is an additional variable required for CM operation, and it ranges from 10 to 100mN [ 198 ]. Webb30 nov. 2024 · Smaller-field systems can be used to pattern large substrates by stitching together multiple exposures, but this affects both productivity and yield because of the …
