Lithography optical system
WebPhotolithography (also optical lithography) is a process used in microfabrication to selectively remove parts of a thin film (or the bulk of a substrate). It uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical (photoresist, or simply "resist") on the substrate.A series of chemical treatments then engraves the exposure … WebWith outstanding flexibility, direct writing grayscale lithography enables the generation of high precision microstructures for the implementation into optical systems.Thus, individual solutions for refractive and diffractive micro optical elements, even on non-standard or non-flat surfaces, can be realized in close collaboration with design and integration.

WebSuch an optical system is said to be diffraction-limited, since it is diffraction effects and not lens aberrations which, for the most part, determine the shape of the image. There are two major classes of projection lithography tools – scanning and step-and-repeat systems. WebLaser Lithography. The intensities in the resist are calculated by incoherent superposition of the partially coherent beam using the systems parameters wavelength, numerical aperture (NA), beam size on substrate, (or beam radius and focal length of the tool optics).
