Disclosed is a method for fabricating of a semiconductor device. The method includes receiving a first layout including patterns for the fabrication of the semiconductor device, performing machine learning-based process proximity correction (PPC) based on features of the patterns of the first layout to generate a second layout, and performing optical proximity correction (OPC) on the second layout to generate a third layout.

Method and computing device for manufacturing semiconductor device

With respect to each layout pattern of a plurality of layout patterns included in a layout for semiconductor processes, where the layout includes schematic information to form process patterns of a semiconductor device, vertical features indicating an effect of a lower structure on the process patterns are determined, and the lower structure indicates a structure that is formed in the semiconductor device before the process patterns are formed. A machine learning module is trained based on a training layout and the vertical features of the training layout. A design layout with schematic information to form target process patterns is corrected based on the trained machine learning module, the design layout and the vertical features of the design layout. Reliability and integration of the layout for the semiconductor processes may be increased by correcting the layout based on the vertical features and the horizontal features.

Methods and devices of correcting layout for semiconductor processes using machine learning

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.

Electronic device for manufacturing semiconductor device and operating method of electronic device

A method of manufacturing a semiconductor device includes forming a lower mold having lower layers stacked on a substrate and lower channel structures passing therethrough; forming an upper mold including upper layers stacked on the lower mold and upper channel structures passing therethrough; removing the upper mold to expose an upper surface of the lower mold; separating an upper original image in which traces of the upper channel structures are displayed, and a lower original image in which the lower channel structures are displayed, from an original image capturing the upper surface of the lower mold; inputting the upper original image into a learned neural network to acquire an upper restored image in which cross sections of the upper channel structures are displayed; and comparing the upper restored image with the lower original image to verify an alignment state of the upper and lower molds.
