Method of determining stopping powers of design structures with respect to a traveling particle

摘要

A computer program product, comprising a computer readable storage device having a computer readable program code stored therein, said program code including an algorithm adapted to be executed by a computer to implement a method. First, design information of a design structure is provided including a back-end-of-line layer of an integrated circuit which includes N interconnect layers, wherein N is a positive integer. Next, each interconnect layer is divided into multiple pixels. Next, a first path of a traveling particle in a first interconnect layer of the N interconnect layers is determined. Next, M path pixels of the multiple pixels of the first interconnect layer on the first path of the traveling particle are identified, wherein M is a positive integer. Next, a first loss energy lost by the traveling particle due to its completely passing through a first pixel of the M path pixels is determined.
