Abstract:
1. A topography simulation apparatus comprising: a division module configured to obtain data representing topography of a substance of a semiconductor device and to divide the topography of the substance in the data into first to n-th layers, where n is an integer of two or more; a flux calculation module configured to calculate, for each of the first to n-th layers, a flux of particles which reach a surface of the substance in each layer and contribute to processing of the topography of the substance; and a topography calculation module configured to calculate, for each of the first to n-th layers, an amount of change of the topography of the substance in each layer based on the flux, wherein the flux calculation module calculates the flux in a k-th layer based on the flux in a (k-1)-th layer adjacent to the k-th layer and a transmission probability of the particles in the k-th layer, where k is an integer from 2 to n.
