WebMany common yellow foils have a short wavelength transmission (< 500 nm) of approx. 1 % or higher, which is not low enough for reprodu-cible litho processes. If unsuited polymers are used for the yellow foil, thermal stress from neighbored light sources can form small cracks in the foil over the years which transmit short wavelength light. UV ...

WebWhat is Lithography? • Lithography is the transfer of geometric shapes on a mask to a smooth surface. • The process itself goes back to 1796 when it was a printing method … WebFigure 5.1 illustrates schematically the lithographic process employed in IC fabrication. As shown in Figure 5.1(b), the radiation is transmitted through the clear parts of the mask and makes the exposed photoresist insoluble in the developer solution, thereby enabling the direct transfer of the mask pattern onto the wafer.
