Substrate holder, lithographic apparatus, and device manufacturing method
Abstract:
A substrate holder for use in a lithographic apparatus. The substrate holder comprises a main body, a plurality of burls and a heater and/or a temperature sensor. The main body has a surface. The plurality of burls project from the surface and have end surfaces to support a substrate. The heater and/or temperature sensor is provided on the main body surface. The substrate holder is configured such that when a substrate is supported on the end surfaces, a thermal conductance between the heater and/or temperature sensor and the substrate is greater than a thermal conductance between the heater and/or temperature sensor and the main body surface.
