After spinning a photoresist on a wafer, we could pattern it with an electron beam. A … The beam diameter or beam width of an electromagnetic beam is the diameter along any specified line that is perpendicular to the beam axis and intersects it. Since beams typically do not have sharp edges, the diameter can be defined in many different ways. Five definitions of the beam width are in common use: D4σ, 10/90 or 20/80 knife-edge, 1/e , FWHM, and D86. The beam width can be measured in units of length at a particular plane perpendicular to the beam axis, but it ca… cinderella story christmas wish 123movies
