WebApr 4, 2024 · In 2014, Takafumi Uemura et al. (University of Tokyo) reported a transit frequency of 20 MHz for organic TFTs fabricated by a combination of photolithography and lift-off for the primary gate electrodes, self-aligned photolithography and lift-off for the secondary (“split”) gate electrodes, and shadow-mask lithography (using an extremely ... 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.
