Lithography is the most complex and criticalReducer servo harmonic SHA20P100CG-C08B200 process step in the semiconductor chip production process, which is time-consuming and costly. The difficulty and key point of semiconductor chip production is to transfer the circuit diagram from the mask to the silicon wafer. Reducer servo harmonic SHA20P100CG-C08B200This process is realized by photolithography. The process level of photolithography directly determines the process level and performance level of the chip. The chip requires 20-30 times of photolithography during production,Reducer servo harmonic SHA20P100CG-C08B200 which takes about 50% of the IC production link and 1/3 of the chip production cost.
