A electrical connection element includes a planar mating surface adapted for mating with a metal bonding surface, a rim that forms an enclosed shape around the planar mating surface, and a plurality of outgassing grooves formed in the planar mating surface, wherein each of the outgassing grooves comprises a proximal end that is spaced apart from the rim and a distal end that intersects the rim, and wherein a cross-sectional area of each of the outgassing grooves increases along a lengthwise direction going from the proximal end to the distal end.

Various aspects relate to mechanisms for coupling a three-dimensional semiconductor cube to a host substrate including a plurality of substrate communication points. The three-dimensional semiconductor cube includes a plurality of cube communication points corresponding to the plurality of substrate communication points and at least one mounting mechanism that couples the three-dimensional semiconductor cube to the host substrate.
