Abstract:
1. A layout determination method for determining a layout of semiconductor devices that are to be created on a substrate by carrying out an exposure process, comprising: (a) determining a number of semiconductor devices to be created on one substrate using a computer, based on exposure data of the semiconductor devices, a time limit of delivery of the semiconductor devices and a number of substrates to be used for production of the semiconductor devices; (b) obtaining coordinates of semiconductor devices arrangeable on the substrate, based on the exposure data; and (c) determining the layout of the semiconductor devices to be created on the substrate, based on the exposure data, the number of semiconductor devices and the coordinates of the semiconductor devices, wherein said step (a) calculates the number of semiconductor devices to be created on one substrate, based on a time required for exposure per one semiconductor device, an exposure time per one layer of each semiconductor device, a total number of shots per one semiconductor device, and an exposure time per one shot.
