Abstract:
1. A computer-readable, non-transitory medium storing a three-dimensional device simulation program, which when executed by a computer, causes the computer to perform a method of generating a three-dimensional model of a device by using a mask data, the method comprising: acquiring cross-sectional feature information indicating a cross-sectional feature of an edge part of a mask; and calculating the three-dimensional model using the mask data and the cross-sectional feature information, wherein the calculating the three-dimensional model includes breaking a feature of a mask pattern indicated by the mask data into a plurality of edge parts, calculating a reference edge position projected onto a base layer for each of the edge parts, calculating a first edge position that is moved from the reference edge position on the base layer by a height of the film thickness, calculating a second edge position on the base layer from the reference edge position on the base layer and the cross-sectional feature information, and calculating an edge slope feature based on the first edge position, second edge position and the cross-sectional feature information.
