    Abstract: Provided are an optical proximity correction (OPC) method capable of maintaining full-chip bias consistency and a mask manufacturing method including the OPC method. The OPC method includes obtaining a first optical proximity corrected (OPCed) design layout by implementing a first OPC on an OPC target design layout; performing a reverse dissection on the OPC target design layout based on the first OPCed design layout to generate first segments; performing a reverse correction to allocate first biases of the first OPCed design layout to the first segments of the OPC target design layout; determining a full-chip representative bias based on a segment grouping of the first segments; applying the full-chip representative bias to an entire chip area; preparing mask data based on the full-chip representative bias that has been applied to the entire chip area; and exposing a mask substrate based on the mask data.

    Abstract: Disclosed is an operating method of an electronic device which includes receiving a design layout for manufacturing the semiconductor device, generating a first layout by performing machine learning-based process proximity correction (PPC), generating a second layout by performing optical proximity correction (OPC), and outputting the second layout for a semiconductor process. The generating of the first layout includes generating a first after cleaning inspection (ACI) layout by executing a machine learning-based process proximity correction module on the design layout, generating a second after cleaning inspection layout by adjusting the design layout based on a difference of the first after cleaning inspection layout and the design layout and executing the process proximity correction module on the adjusted layout, and outputting the adjusted layout as the first layout, when a difference between the second after cleaning inspection layout and the design layout is smaller than or equal to a threshold value.
