Abstract:
A substrate holder (100) for a lithographic apparatus has a main body having a thin-film stack (110) provided on a surface thereof. The thin-film stack forms an electronic or electric component such as an electrode, a sensor, a heater, a transistor or a logic device, and has a top isolation layer. A plurality of burls (106) to support a substrate (W) are formed on the thin-film stack or in apertures of the thin-film stack.
Abstract:
A method of manufacturing an object holder (100) for use in a lithographic apparatus, the object holder comprising one or more electrically functional components, the method comprising: using a composite structure comprising a carrier sheet (20) different from a main body (100a) of the object holder and a layered structure comprising one or a plurality of layers (22) and formed on the carrier sheet; connecting the composite structure to a surface of the main body such that the layered structure is between the carrier sheet and the surface of the main body; and removing the carrier sheet from the composite structure, leaving the layered structure connected to the main body.
Abstract:
A substrate holder for a lithographic apparatus has a planarization layer provided on a surface thereof. The planarization layer provides a smooth surface for the formation of an electronic component such as a thin film electronic component. The planarization layer may be provided in multiple sub layers. The planarization layer may smooth over roughness caused by removal of material from a blank to form burls on the substrate holder.
Abstract:
Substrate holder (100) for use in a lithographic apparatus, the substrate holder comprising a main body having a first surface and a second surface opposite the first surface.A plurality of first burls are provided on the first surface, the first burls having end surfaces to support a substrate. A plurality of second burls are provided on the second surface to support the substrate holder on a structure. The plurality of first burls each comprise a lower body portion protruding from the first surface and an upper body portion above the lower body portion, the lower body portions comprise a different material from the upper body portions, and the upper body portions comprise diamond-like carbon.
