A sample holder of the present invention includes a base body formed of ceramic substrates laminated to each other and having an upper surface functioning as a sample holding surface. In this sample holder, the base body includes a first ceramic substrate including a flow path for a heating medium and a second ceramic substrate which is laminated at an upper side than the first ceramic substrate, which has an upper surface functioning as the sample holding surface, and which is formed of the same material as that of the first ceramic substrate, and the average grain diameter of ceramic grains forming the second ceramic substrate is smaller than that of ceramic grains forming the first ceramic substrate.

A wafer table structure providing a single wafer table surface suitable for handling both wafers and film frames includes a base tray having a set of compartments formed therein by way of a set of ridges formed in or on an interior base tray surface; a hardenable fluid permeable compartment material disposed within the set of base tray compartments; and a set of openings formed in the base tray interior surface by which the hardened compartment material is exposable to negative or positive pressures. The base tray includes a first ceramic material (e.g., porcelain), and the hardenable compartment material includes a second ceramic material. The base tray and the compartment material are simultaneously machinable by way of a standard machining process to thereby planarize exposed outer surfaces of the base tray and the hardened compartment material at an essentially identical rate for forming a highly or ultra-planar wafer table surface.
摘要:
The invention relates to a method for connecting two components (1, 2) having different stiffnesses (E1, E2), comprising: bonding a plate-shaped body (3) onto the component (1) having greater stiffness (E1), the bonding being preferably performed using a joining agent, in particular an adhesive, correcting deformations produced by the bonding on the plate-shaped body (3), and connecting the component (2) having the lower stiffness (E2) to the plate- shaped body (3), in particular by wringing, by anodic bonding or by fusion bonding. The invention also relates to a composite structure (5), which has been produced according to the method and which can serve, for example, as a holding device for a wafer (6). Moreover, the first component (1) can serve as a carrier for the second component (2), e.g. if the latter is embodied as an EUV mirror.

A carbon material, a jig, and a method of manufacturing the carbon material are provided that can prevent dust emission and also improve the temperature resistance under a nitrogen atmosphere. In a carbon material having a carbon substrate and a metal carbide layer formed on a surface of the carbon substrate, the metal carbide layer includes molybdenum carbide and/or iron carbide. The carbon substrate embedded in a surface modifying agent containing a pyrolytic hydrogen halide generating agent and molybdenum particles and/or iron particles is heat-treated together with a carbon member other than the carbon substrate.
