Low lithography
WebStepper is short for step-and-repeat camera. Steppers are an essential part of the complex process, called photolithography, which creates millions of microscopic circuit elements on the surface of silicon wafers out of which chips are made. These chips form the heart of ICs such as computer processors, memory chips, and many other devices. Weblithography method would supply the easy and low-cost fabrication approach for subwavelength functional devi- ces. 24−27 Meanwhile, the separation mode would also bring
