Abstract: Embodiments generally provide an apparatus and method for processing substrates using a multi-chamber processing system (e.g., a cluster tool) that has an increased system throughput, increased system reliability, substrates processed in the cluster tool have a more repeatable wafer history, and also the cluster tool has a smaller system footprint. In one embodiment, the cluster tool is adapted to perform a track lithography process in which a substrate is coated with a photosensitive material, is then transferred to a stepper/scanner, which exposes the photosensitive material to some form of radiation to form a pattern in the photosensitive material, which is then removed in a developing process completed in the cluster tool.

Abstract: A chuck for a semiconductor workpiece features integrated resistive heating and electrostatic bipolar chucking elements on a thermal pedestal. These integrated heating and chucking elements maintain wafer flatness, as well as uniformity of an underlying gap accommodating a thermal gas between the workpiece and the chuck. In accordance with one embodiment of the present invention, a laminated Kapton wafer heater is attached to the top of the thermal surface, under the wafer: At least two electrical voltage zones are isolated within the heater, in order to create a chucking force between the chuck and the wafer without having to contact the wafer with an electrical conductor. These voltage zones can be created by using separate conducting elements as well as by imposing a DC bias on zones including the resistive heating elements.

The protrusions define contact surfaces on which grooves can be formed.

Abstract: The present invention provides an electrostatic chuck having a dielectric layer with improved porosity and electrical properties, and a method for fabricating the dielectric layer and applying the layer to a pedestal to form a portion of an electrostatic chuck. The dielectric layer is formed by a detonation gun process which includes igniting a fuel gas mixture to form a detonation wave and propelling aluminum oxide powder onto the pedestal at high speeds. The dielectric layer has a porosity of less than 1 percent of its total volume, which improves the electrical properties of the chuck, such as its dielectric strength and the dielectric constant. In addition, the low porosity decreases the adsorption of moisture and other gases into the dielectric layer, which further enhances the electrical properties of the chuck.

Abstract: A method and apparatus for noncontact temperature measurement of a substrate insitu by measuring the temperature of a substrate support member and an intermediate member located between the substrate and the substrate support member. The intermediate member has a given heat transfer surface area adjacent both the substrate and the substrate support member and high thermal conductivity so that the intermediate member rapidly approaches a steady state surface temperature after the substrate is positioned in the substrate support member. In this arrangement, the temperature of the substrate can be determined either by calibration or application of a heat transfer equation. Various temperature measuring instruments may be used, including a light probe located in the substrate support member normal to the surface of the intermediate member to measure the radiation from a temperature sensitive material deposited on the bottom surface of the intermediate member.

Abstract: An improved substrate support and method for operating in which multiple pressure zones are provided on the surface of the substrate support. A seal area is provided between the different zones to allow different gas pressures in the two zones. A higher gas pressure is provided to a zone corresponding to an area of the substrate where greater heat transfer is desired. The gap between the substrate support and the gas pressure are selected to provide the desired amount of heat transfer. Another aspect is limited substrate contact using protrusions, to maximize heat transfer gas flow. A closed loop control system varies the heat transfer gas pressure in accordance with a temperature sensor. For an electrostatic chuck, the dielectric thickness is varied to give a higher electrostatic force at the periphery of the substrate.
