Temperature control in white ice laminate countertop etching process is important for semiconductor 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 jumbo tuz de?irmeni network-based fuzzy inference system (ANFIS) using a field-programmable gate array (FPGA) to improve the effectiveness.The proposed method adjusts 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.
