Abstract:
PROBLEM TO BE SOLVED: To improve the accuracy of a device structure formed by a maskless lithography system. SOLUTION: A method of producing optimized setpoint data for controlling the element operation of an array of individually controllable elements in a maskless system, and systems therefor are provided. Optimization is based on an estimated device structure and/or an estimated dose pattern that utilize one or more of the following factors: the low-pass characteristics of a projection system, the configuration of an illumination system, and the process window characteristics.

Abstract:
Disclosed herein is a computer-implemented defect prediction method for a device manufacturing process involving processing a portion of a design layout onto a substrate, the method comprising: identifying a hot spot from the portion of the design layout; determining a range of values of a processing parameter of the device manufacturing process for the hot spot, wherein when the processing parameter has a value outside the range, a defect is produced from the hot spot with the device manufacturing process; determining an actual value of the processing parameter; determining or predicting, using the actual value, existence, probability of existence, a characteristic, or a combination thereof, of a defect produced from the hot spot with the device manufacturing process.
