Abstract: The invention provides for cooling a semiconductor die. The die has plurality of micro-channels. A condenser is in fluid communication with the micro-channels such that the die heats vaporizes fluid at the die to force fluid towards the condenser, and such that gravity pressurizes cooler condenser fluid towards the die. A semiconductor plate such as glass may couple with the die to seal the micro-channels and to form a plurality of fluid conduits for the fluid. Generally, the fluid is alcohol. A first fluid conduit and a second fluid conduit couple between the die's micro-channels and the condenser to form a closed loop thermosyphon system. The condenser is preferably constructed and arranged above the die such that gravity forces cooler fluid to the micro-channels. The micro-channels may be shaped for preferential fluid flow along one direction of the die. The condenser may contain fins to enhance heat transfer to air adjacent the condenser.

Abstract: A method and apparatus for measuring electrical current using a piezoelectric sensor. A first electrical conductor for carrying a current to be sensed is attached to one face of a piezoelectric element. A second electrical conductor for carrying a reference current, the second electrical conductor is attached to the opposite face of the piezoelectric element and is aligned parallel to the first electrical conductor. The force between the first and second electrical conductors is applied to the piezoelectric element and produces an electrical potential between the faces of the piezoelectric element. The electrical potential may be used to determine the current in the first conductor.
