    摘要: Carbon-doped semiconductor material portions are formed on a subset of surfaces of underlying semiconductor surfaces contiguously connected to a channel of a field effect transistor. Carbon-doped semiconductor material portions can be formed by selective epitaxy of a carbon-containing semiconductor material layer or by shallow implantation of carbon atoms into surface portions of the underlying semiconductor surfaces. The carbon-doped semiconductor material portions can be deposited as layers and subsequently patterned by etching, or can be formed after formation of disposable masking spacers. Raised source and drain regions are formed on the carbon-doped semiconductor material portions and on physically exposed surfaces of the underlying semiconductor surfaces. The carbon-doped semiconductor material portions locally retard dopant diffusion from the raised source and drain regions into the underlying semiconductor material regions, thereby enabling local tailoring of the dopant profile, and alteration of device parameters for the field effect transistor.

    摘要: A composite brake drum for use in a drum brake assembly includes a one-piece mounting flange and shell and a liner cast integrally in a shell portion thereof. The method for forming the composite brake drum of this invention includes the steps of: (a) providing a generally circular metal blank having an initial pilot hole inner diameter; (b) spin forming the metal blank to produce a one-piece brake drum component defining a center longitudinal axis and including a cylindrical shell having a squealer band which defines a squealer band outer diameter, a mounting flange extending radially inwardly from one end of the shell toward the center longitudinal axis, and an annular lip extending radially inwardly from an opposite end of the shell toward the center longitudinal axis, and wherein the shell, the flange, and the lip cooperate to define a cylindrical mold cavity; (c) subsequent to step (b), centrifugally casting a liner in situ within the mold cavity of the brake drum component to thereby produce the composite vehicle brake drum; and (d) subsequent to step (c), machining the initial pilot hole inner diameter to a final pilot hole inner diameter by locating off of the squealer band outer diameter.

    摘要: An article supports a workpiece during thermal processing. At least three elongated support members, e.g., support pins, extend upwardly from an element such as support arms for supporting the workpiece. Each of the support members includes a first portion adjacent to the workpiece. A second portion extends downwardly from the first portion. The first portion can have a thermal response faster than the thermal response of the workpiece and the second portion can have a slower thermal response. A removable element may be mounted to the support member for adjusting the thermal response of the support member. With removable elements, the support members can be adjusted to cause no net transfer of heat to or from the workpiece.
