Title: Method for optimizing matching network of semiconductor process apparatus

Abstract: A method for optimizing matching network between an output impedance and aninput impedance in a semiconductor process apparatus is disclosed. Themethod includes the steps of: providing a neural network capable of beingtrained through repeated learning; training the neural network frompreviously performed process conditions; setting up an initial value;comparing the initial value with a theoretically calculated value, toobtain error between the values; and repeating the training, setting, andcomparing steps until the error becomes zero.
