Abstract
A machine learning (ML)-based process proximity correction (PPC) method includes receiving a first layout of an after clean inspection (ACI) including patterns for manufacturing a semiconductor device, extracting features of a first pattern from the first layout, generating a prediction model through ML based on the features of the first pattern, generating an ACI target having a maximum process margin by comparing an upper limit value and a lower limit value of the ACI for at least one condition, generating a second layout of an after development inspection (ADI) by correcting the first layout to correspond to the ACI target, and predicting the ACI through the prediction model, based on the second layout of the ADI.
