Semiconductor chip principle

Now let's look at the principle of semiconductor chip. The working principle of the chip is: the circuit is manufactured on the surface of the semiconductor chip for operation and processing. Integrated circuits have two main advantages over discrete transistors: cost and performance. The low cost is because the chip prints all components as a unit through photolithography technology, rather than making only one transistor at a time. The high performance is due to the fast switching of components, which consumes less energy because the components are small and close to each other. In 2006, the chip area increased from a few square millimeters to 350mm & sup2;, Per mm & sup2; It can reach a million transistors. Digital integrated circuits can contain anything, from thousands to millions of logic gates, flip flops, multitasking and other circuits on a few square millimeters. The small size of these circuits enables higher speed, lower power consumption (see low power design) and lower manufacturing cost compared with board level integration. These digital ICs, represented by microprocessors, digital signal processors and microcontrollers, use binary to process 1 and 0 signals. （BanDaoTiXinPianYuanLi）
