    摘要: A method for optimizing alignment performance in a fleet of exposure systems involves characterizing each exposure system in a fleet of exposure systems to generate a set of distinctive distortion profiles associated with each exposure system. The set of distinctive distortion profiles are stored in a database. A wafer having reference pattern formed thereon is provided for further pattern fabrication and an exposure system is selected from the fleet to fabricate a next layer on the wafer. Linear and higher order parameters of the selected exposure system are adjusted using the distinctive distortion profiles to model the distortion of the reference pattern. Once the exposure system is adjusted, it is used to form a lithographic pattern on the wafer.

    摘要: An object is placed at a particular distance away from the nonreflecting side of a mirror, such that the gravitational force of the object affects the mirror. A laser is then pointed at the opposite, reflecting side of the mirror, thereby itself reflecting off the mirror and going back in to the cavity of the laser, creating a mode-hopping effect. The mirror will be affected by three forces, the force of a spring (F s ), the force of a modulating signal (F Ms ). created by an electro mechanical device attached to the mirror, and the gravitational force of objects as they approach and recede away from the mirror.
