PHOTOLITHOGRAPHY OVERVIEW FOR MICROSYSTEMS

WebPhotolithography. In a microelectronic circuit, all the circuit. elements (resistors, diodes, transistors, etc.) are formed in the top surface of a wafer (usually. silicon). These circuit elements are interconnected in a. complex, controlled, patterned manner. Consider the simple case of a silicon p-n. WebPhotolithography is a binary pattern transfer. there is no gray-scale, color, nor depth to the. image. This pattern can be used as a resist to substrate. etchant, or a mold, and other forms of design. processes.
