摘要： In a heater unit, comprising a lower metallic base, an upper metallic base placed closely over an upper surface of said lower base, and a resistance heater wire received in a groove defined between opposing surfaces of said lower and upper bases, ceramic powder is filled in said groove to keep said heater wire at least away from a wall surface of said groove. Thus, the heater wire can be directly installed in the groove of the base without the intervention of a sheath pipe so that the heater wire can be bent in a desired dense pattern, and the heater unit can be heated both rapidly and uniformly. Also, the ceramic powder filled in the groove improves the heat transfer, and this even further enhances the these advantages of the present invention.

摘要： An upper metallic base is placed over a lower metallic base with a resistance heater element interposed between them so as to cause a plastic deformation to at least one of the opposing surfaces until the corresponding surfaces conform to an outer profile of the heater element, and the opposing surfaces of the lower and upper bases, and the resistance heater element are substantially entirely bonded to one another by a metallic bonding which may consist of brazing, soldering or diffusion bonding. Because the metallic bonding provides a favorable heat conduction, and can thereby improve the thermal efficiency and prevent local heating, a rapid temperature rise and uniform heating are made possible. Because the base consists of two parts, the material for the base can be selected from a wide range of materials including those capable of withstanding high temperatures and corrosive materials.
摘要翻译： 上金属底座放置在下金属底座上，电阻加热元件插在它们之间，以便对相对表面中的至少一个造成塑性变形，直到相应的表面符合加热器元件的外轮廓，并且 下部和上部基座的相对表面和电阻加热器元件通过可由钎焊，焊接或扩散接合构成的金属接合而彼此基本上完全结合。 由于金属接合提供有利的热传导，因此可以提高热效率并防止局部加热，可以实现快速的温度上升和均匀的加热。 由于底座由两部分组成，所以基材的材料可以从宽范围的材料中选出，包括耐高温和腐蚀性材料的材料。

摘要： The present invention provides a heater unit which can improve temperature uniformity of a heated object at the time of heating the object. A second heat conductor 32 which is the radial internal part of shaft 22 has a lower heat transfer ratio than a first heat conductor 30 which is the radial external part of shaft 22. As a result, in the case where a heated state and a non heated state of the resistance heating element 18 are repeatedly switched, the movement of heat from the front part 22B of the shaft 22 to the base point part 22A is suppressed by the second heat conductor 32 compared to the first heat conductor 30. As a result, in the part which confronts the hollow part 42 of the shaft 22 in the heater plate 16, the time required to heat the heater plate 16 and the wafer 28 to be heated to a desired heating temperature is shortened when compared to a conventional heater unit. Therefore, it is possible to improve the uniformity of the temperature of the wafer 28 which is to be heated by the heater plate 16.

摘要： A substrate supporting apparatus includes a plate member of an aluminum alloy having a flat upper surface, bottomed pits formed in the plate member, and spacer members held in the pits, individually. The spacer members are sapphire spheres. The diameter of each spacer member is a little smaller than that of each pit. The upper end of each spacer member projects from the upper surface of the plate member. A spot facing is formed in a region that includes the open edge portion of the pit. A bending portion which is obtained by plastically deforming the open edge portion of the pit toward the spacer member is formed on a bottom surface of the spot facing. A V-shaped groove is formed behind the bending portion.
