Abstract:
A support assembly for use in semiconductor processing includes an application substrate, a heater layer disposed directly onto the application substrate, an insulation layer disposed onto the heater layer, and a second substrate disposed onto the insulation layer. The heater layer is directly disposed onto the application substrate by a layered process such that the heater layer is in direct contact with the application substrate. The application substrate defines a material having a relatively low coefficient of thermal expansion that is matched to a coefficient of thermal expansion of the heater layer.
Abstract:
A method of assembling an optical element on top of an active component in a substrate, by providing a substrate with active component and an optical element with a base and lateral base walls, fixating a bottom surface of a frame holder with opening and lateral frame walls arranged in a polygonal structure to the substrate so that the opening is positioned over the active component, and mounting the optical element in the opening so the lateral frame walls apply lateral confining mechanical force on the lateral base walls.
Abstract:
Embodiments of an apparatus for controlling a temperature of an electrostatic chuck in a process chamber are provided herein. In some embodiments, the apparatus includes an electrostatic chuck disposed in a process chamber, the electrostatic chuck including a ceramic plate having a substrate supporting surface, and a cooling assembly including a plurality of cooling plates disposed below the electrostatic chuck to adjust the cooling capacity of the electrostatic chuck. In some embodiments, the plurality of cooling plates includes an inner cooling plate configured to control a temperature of a center portion of the electrostatic chuck, and an outer cooling plate configured to control a temperature of an outer portion of the electrostatic chuck. In some embodiments, the plurality of cooling plates includes an upper cooling plate that contacts a bottom surface of the electrostatic chuck, and a lower cooling plate which contacts a bottom surface of the upper cooling plate.
Abstract:
An article with an etch resistant coating is disclosed. The article is a heating element, wafer carrier, or electrostatic chuck. The article has a base substrate made of a ceramic or other material, and further has one or more electrodes for resistance heating or electromagnetic chucking or both. The eth resistant coating has a plurality of regions made from materials having different electrical volume resistivities, such that the overall coating has a bulk resistivity that can be tailored by varying the relative size of each region.
Abstract:
An apparatus and a method for removing foreign materials from a substrate which eliminate a possibility of readhesion of the foreign materials adhered on the substrate by surely removing the foreign materials and are applicable even to large substrates. The foreign material removing apparatus is provided with electrostatic chucks (2, 3) which form a substrate attracting plane (4) for attracting the substrate (1); a resin sheet supplying means (9) for supplying the substrate attracting plane (4) with a resin sheet (5); a resin sheet recovering means (13) for recovering the supplied resin sheet (5), and a substrate transfer means for transferring the substrate (1). The substrate (1) supplied to the electrostatic chucks (2, 3) by the substrate transfer means is permitted to be attracted to the substrate attracting plane (4) through the resin sheet (5), and the foreign materials (22) adhered on a side of the substrate attracting plane (4) of the substrate (1) are transferred onto the resin sheet (5) and removed.
