    Abstract: Piezoelectric devices are described fabricated in packaging buildup layers. In one example, a package has a plurality of conductive routing layers and a plurality of organic dielectric layers between the conductive routing layers. A die attach area has a plurality of vias to connect to a microelectronic die, the vias connecting to respective conductive routing layers. A piezoelectric device is formed on an organic dielectric layer, the piezoelectric device having at least one electrode coupled to a conductive routing layer.

    Abstract: A thermal management solution may be provided for a microelectronic system, wherein a jumping drops vapor chamber is utilized between at least one microelectronic device and an integrated heat spreader. The microelectronic system may comprise a microelectronic device attached by an active surface thereof to a microelectronic substrate. The integrated heat spreader, having a first surface and an opposing second surface, is also attached to the microelectronic substrate with a jumping drops vapor chamber disposed between a back surface of the microelectronic device and the integrated heat spreader second surface. The jumping drops vapor chamber may comprise a vapor space defined by a hydrophilic evaporation surface on the microelectronic device back surface, a hydrophobic condensation surface on the integrated heat spreader second surface, and at least one sidewall extending between the hydrophilic evaporation surface and the hydrophobic condensation surface with a working fluid disposed within the vapor space.
