Web2.5.1 Contact and Proximity Printing. A simple and straight forward approach is contact printing. In contact printing, the mask is pressed against the resist-coated wafer during exposure, i.e., the optical part shown in Figure 2.3 or Figure 2.4 is missing, but the other components like the illuminator and mask are kept.

Webect exact lithography behavior which is extremely challenging, we build a neural network architecture that allows ap-proximated computing ow as in traditional lithography models, which adds an inductive bias to the model architecture [19]. We will show later that the op-timized Fourier Unit resembles physical lithography equations, ensuring faster WebImmersion lithography is now in use and is expected to allow lenses to be made with numerical apertures greater than 1.0. Lenses with NA s above 1.2 or 1.3 seem likely. If an immersion fluid with a refractive index closer to that of the photoresist can be found, numerical apertures of up to 1.5 might be possible. the origin coffee
