Lithography ppt
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 using ink, metal plates and paper. • In modern semiconductor manufacturing, photolithography uses optical radiation to image the mask on a silicon wafer using Web浸没式光刻机采用折射和反射相结合的光路设计(catadioptric)。 这种设计可以减少投影系统光学元件的数目,控制像差和热效应,实现1.35NA。 图2(a)是一种浸没式光刻机投 …

WebIn this paper, we have optimized the i-line lithographic techniques for the various pattern shape and density for 0.30 micrometers design rule. Optimum duty ratio was tried to find for line and space, contact hole patterns. The basic rule is to keep the minimum Cr width over 0.30 micrometers mask.
