  • Wafer chuck with aerodynamic design for turbulence reduction
    Patent number: 10563298
    Abstract: A rotatable wafer chuck includes chuck arms and wafer holders that are aerodynamically shaped to reduce turbulence during rotation. A wafer holder may include a friction support and an independently rotatable vertical alignment member and clamping member that is shaped to reduce drag. The shape reduces turbulence during edge bevel etching to improve the uniformity of the edge exclusion and during high-speed rotation to improve particle performance.
    Type: Grant

  • Amorphous metal foam as a property-matched bone scaffold substitute
    Patent number: 8444745
    Abstract: Amorphous metal foams and methods of making the same are provided. The amorphous metal foams have properties matching those of natural bone, enabling their use as bone replacement scaffolds. In one embodiment, for example, an amorphous metal foam has a density-dependent stiffness (or Young's modulus, denoted E) ranging from about 640?3.75 ?o ??ou? 2900?0.78, and a density dependent strength (?y) greater than about 8.1?2.57, wherein ? (the density) is less than about 1.7 g/cc.

  • Amorphous Fe and Co based metallic foams and methods of producing the same
    Patent number: 7806997
    Abstract: Amorphous Fe-based metal foams and methods of preparing the same are provided. The Fe-based foams are prepared from Fe-based metal alloys of low hydrogen solubility having an atomic fraction of Fe greater than or equal to the atomic fraction of each other alloying element. A method for producing the Fe-based foams includes the in situ decomposition of a hydride in a molten Fe-based alloy.

  • AMORPHOUS FE AND CO BASED METALLIC FOAMS AND METHODS OF PRODUCING THE SAME
    Publication number: 20080118387
    Abstract: Amorphous Fe- and Co-based metal foams and methods of preparing the same are provided. The Fe- and Co-based foams are prepared from Fe- and Co-based metal alloys of low hydrogen solubility having an atomic fraction of Fe or Co greater than or equal to the atomic fraction of each other alloying element. A method for producing the Fe- and Co-based foams includes the in situ decomposition of a hydride in a molten Fe- or Co-based alloy.
