Abstract:
A microelectronic assembly is provided, having thermoelectric elements formed on a die so as to pump heat away from the die when current flows through the thermoelectric elements. In one embodiment, the thermoelectric elements are integrated between conductive interconnection elements on an active side of the die. In another embodiment, the thermoelectric elements are on a backside of the die and electrically connected to a carrier substrate on a front side of the die. In a further embodiment, the thermoelectric elements are formed on a secondary substrate and transferred to the die.

Abstract:
An embodiment of the invention relates to a device comprising an array of optical magnetometers. The magnetometers comprise a light source, a container having a chamber filled with an atomic vapor, and a photo detector capable of detecting optical properties of the atomic vapor. The substrate and the array of the magnetometers are designed such that the magnetometers are able to detect weak magnetic fields. Also, the magnetometers are capable of detecting distinct portions of a magnetic field, such as a non-uniform magnetic field, using a single or a plurality of the magnetometers in the array simultaneously. Other embodiments of the invention include methods of making a device that comprises an array of optical magnetometers and methods of detecting a magnetic field using the device. The device and method can be used in medical diagnostics, such as detecting biomagnetic activities of the human's heart and brain.
