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. WebOptical lithography: How microchips are made. In simple terms, countless grains of sand turn into microchips in a high-precision process. The key ingredients: light and the projection optics for ZEISS SMT's production of semiconductors. The photolithography used to produced logic and memory chips is a multi-stage process.
