发明名称 Lithographic apparatus and method
摘要 A lithographic apparatus comprising a source that generates a beam of radiation, a support structure supporting a patterning device, a substrate table for holding a substrate, and a projection system projecting the patterned radiation beam onto a target portion of the substrate. The lithographic apparatus further comprises a vibration measurement apparatus configured to measure relative vibration between the patterning device and the substrate during exposure of the target portion. A control apparatus adjusts power of the radiation beam to compensate for the effect of the measured relative vibration on the pattern projected onto the substrate.

主权项 1. A lithographic apparatus comprising: a source configured to generate a beam of radiation; a support structure configured to supporting a patterning device, the patterning device serving to impart the radiation beam with a pattern in its cross-section; a substrate table configured to hold a substrate; a projection system configured to project the patterned radiation beam onto a target portion of the substrate; a vibration measurement apparatus configured to measure relative vibration between the patterning device and the substrate during exposure of the target portion; and a control apparatus configured to adjust power of the radiation beam to compensate for effect of the measured relative vibration on the pattern projected onto the substrate.
