Abstract: A machine-learning method for semiconductor process optimization may include inputting semiconductor-related parameters into each of first neural network models and outputting, based on the semiconductor-related parameters, a predicted figure of merit of a semiconductor device as a first output value from each of the first neural network models. After a semiconductor manufacturing process is performed with a semiconductor manufacturing parameter, electrical measurement parameter values may be measured using one or more measuring devices. The semiconductor-related parameters may include electrical measurement parameter values measured on one or more semiconductor devices. The method may also utilize a feedback loop between an output and an input of the first neural network models so that the electrical measurement parameter values can be updated based on an output value of the first neural network models. A second neural network model may also be used. A computing device and a system are also disclosed.
