Abstract: A brazing sheet (1) includes a core material (11) composed of an Al alloy containing 0.40-2.50 mass % Mg; and a filler material (12) composed of an Al alloy containing Mg, 6.0-13.0 mass % Si, and 0.010-0.050 mass % Bi. The filler material is layered on a side of the core material and is exposed at an outermost surface (121). The Mg concentration in the filler material continuously decreases in a direction from a boundary (122) with the core material toward the outermost surface. The Mg concentration (c1/8) is 0.080 mass % or less at a depth (position P1/8) from the outermost surface that is ⅛ of the thickness tf of the filler material (12). The Mg concentration (c7/8) is 15-45% of the amount of Mg in the core material at a depth (position P7/8) from the outermost surface that is ⅞ of the thickness tf of the filler material.

Abstract: A method for the joining of ceramic pieces with a hermetically sealed joint comprising brazing a layer of joining material between the two pieces. The ceramic pieces may be aluminum nitride or other ceramics, and the pieces may be brazed with Nickel and an alloying element, under controlled atmosphere. The completed joint will be fully or substantially Nickel with another element in solution. The joint material is adapted to later withstand both the environments within a process chamber during substrate processing, and the oxygenated atmosphere which may be seen within the interior of a heater or electrostatic chuck. Semiconductor processing equipment comprising ceramic and joined with a nickel alloy and adapted to withstand processing chemistries, such as fluorine chemistries, as well as high temperatures.

Abstract: A laminate sheet including a weldable margin is formed by laminating metal sheets having a core layer disposed therebetween. The core layer is formed of a core material which includes one or more of a viscoelastic, adhesive and acoustic material. The core layer is selectively distributed such that the laminate sheet includes an adhered region providing a laminate structure, and a non-adhered region including a weldable margin. The non-adhered region is adjacent an edge of the core layer and is characterized by a gap between the first and second metal sheets and by an absence of the core layer in the gap. The non-adhered region defines a weldable margin adjacent a core edge configured such that a weld is formable in the weldable margin without heat affecting the core layer. The laminate sheet can be joined by fasteners installed in the non-adhered region.
