摘要： The present disclosure provides a support pedestal that includes a support member including a resistive layer having at least two zones, a routing layer, and a plurality of conductive vias. The resistive layer and the routing layer are disposed in different planes of the support member and are connected by the plurality of vias. The number of zones of the resistive layer is greater than or equal to a number of wires coupled to the routing layer. The routing layer may include a plurality of arm portions that extend from a central region of the routing layer. The support pedestal may further include a second resistive layer disposed along the same plane as the routing layer.

摘要： An assembly includes a first member, a second member adjacent to the first member, and an aluminum material. At least one of the first member and the second member defines at least one trench. The aluminum material is disposed within the trench and bonds the first member to the second member along adjacent faces. In one form, a spacing between the first member and the second member along the adjacent faces is less than 5 μm.

摘要： A method of joining is provided. the method includes preparing a first member, preparing a second member, and forming at least one trench in at least one of the first member and the second member. The method further includes placing a strip of solid aluminum material between the first member and the second member across the trench, bringing the first member and the second member together to contact the solid aluminum material and to form an assembly, and applying a force and heat to the assembly above a melting point of the solid aluminum material such that the solid aluminum material flows into the trench. Additionally, the method further includes applying additional heat to the assembly at or above a wetting temperature of the member in which the trench is formed to bond the first member to the second member along adjacent faces and cooling the assembly.

摘要： A method for operating a heater system including a resistive heating element having a material with a non-monotonic resistivity vs. temperature profile is provided. The method includes heating the resistive heating element to within a limited temperature range in which the resistive heating element exhibits a negative dR/dT characteristic, operating the resistive heating element within an operating temperature range that at least partially overlaps the limited temperature range, and determining a temperature of the resistive heating element such that the resistive heating element functions as both a heater and a temperature sensor. The resistive heating element can function as a temperature sensor in a temperature range between about 500° C. and about 800° C., and the non-monotonic resistivity vs. temperature profile for the material of the resistive heating element can have a local maximum and a local minimum.

摘要： A heater includes at least one resistive element. The at least one resistive element includes a material having a high temperature coefficient of resistance (TCR) such that the resistive element functions as a heater and as a temperature sensor, the resistive element being a material selected from the group consisting of greater than about 95% nickel, a nickel copper alloy, stainless steel, a molybdenum-nickel alloy, niobium, a nickel-iron alloy, tantalum, zirconium, tungsten, molybdenum, Nisil, and titanium. In one form, the heater is a tubular heater with compacted MgO insulation and a metal sheath.
