20230185188 · 2023-06-15 ·

According to one embodiment, a pattern drawing method includes correcting a drawing parameter for a pattern to be drawn on a resist film on a surface of a substrate. The correction being based on drawing information, height information, and dimensional difference information. The drawing information is design data for drawing the pattern on the resist film by irradiating the resist film with an electron beam. The height information indicates changes in surface height of the substrate. The dimensional difference information includes differences between a dimension of a pattern as indicated in the design data and a dimension of a pattern formed on the substrate by processing the substrate using a resist film patterned according to the drawing information as a mask. The correction of the drawing parameter reduces a dimensional difference between design data and a pattern formed on a target portion on the surface of the substrate.

A method for manufacturing-aware editing of circuit layouts driven by predictions regarding predicted manufactured wafer contours generated by a machine-trained network. The method allows for fast edit loops in interactive editing timeframes, in which the predicted manufactured wafer contours corresponding to design edits are presented within seconds of the edits themselves. In some embodiments, the wafer contours take mask OPC/ILT and lithography effects into account, as determined by the machine trained network.
