Temperature control in etching process is important for semiconductor white chocolate digestives manufacturing technology.However, pressure variations in vacuum chamber results in a change in temperature, worsening the accuracy of the temperature of the wafer and the speed and quality of the etching process.This work develops an adaptive network-based fuzzy inference system (ANFIS) using a field-programmable gate array (FPGA) to improve the effectiveness.The proposed method adjusts syil x7 price every membership function to keep the temperature in the chamber stable.The improvement of the proposed algorithm is confirmed using a medium vacuum (MV) inductively-coupled plasma- (ICP-) type etcher.
