    摘要: A wafer has a layer containing silicon, a layer of polycrystalline diamond deposited on the silicon-containing layer, and a bow-compensation layer on the other side of the silicon-containing layer for reducing wafer-bow. A method of making a bonded structure includes an activation process for creating dangling bonds on the surface of one substrate, followed by contact-bonding the surface to a second substrate at low temperature. A bonded structure may include two substrates contact bonded to each other, one substrate including a layer containing silicon, a layer of polycrystalline diamond, a bow-compensation layer for reducing wafer-bow of the first substrate, and the other substrate including gallium nitride, silicon carbide, lithium niobate, lithium tantalate, gallium arsenide, indium phosphide, or another suitable material other than diamond.

    摘要: Provided is cookware made from a bonded multi-layer blank assembly. The cookware has a first metal layer, a second metal layer having a cavity with a plurality of spaced-apart posts protruding from a bottom surface of the cavity, and a perforated graphite layer having a thickness of at least 0.010 in. (0.254 mm) and a plurality of spaced-apart holes formed therethrough. The perforated graphite layer is positioned within the cavity of the second metal layer such that the plurality of spaced-apart posts extend through the plurality of spaced-apart holes. The second metal layer is metallurgically bonded to the first metal layer at least via the plurality of spaced-apart posts. A method of making the bonded multi-layer composite cookware is also disclosed.
