The use of lambda-based design rules must therefore be handled with caution in sub-micron geometries. Course Number and Name BEC010 VLSI DESIGN Course Objectives To learn basic CMOS Circuits. The Mead-conway approach is to characterize the process with a single scalable parameter called lambda, that is process-dependent and is defined as the maximum distance by which a geometrical feature on any one layer can stray from another feature, due to overetching, misalignment, distortion, over or under exposure etc. Design rules are an abstraction of the fabrication process that specify various geometric constraints on how different masks can be drawn.
