摘要: In a projection system for EUV, the positions of mirrors are measured and controlled relative to each other, rather than to a reference frame. Relative position measurements may be made by interferometers or capacitive sensors mounted on rigid extensions of the mirrors.

摘要: A reaction mass and an actuator are used to reduce unwanted vibrations of an optical element in the projection system of a lithographic projection apparatus. The reaction mass may be mechanically connected only to the optical element or may be compliantly mounted to the projection system frame.
