EXTENDED TEMPERATURE OPERATION FOR ELECTRONIC SYSTEMS USING INDUCTION HEATING
Embodiments are generally directed to extended temperature operation for electronic systems using induction heating. An embodiment of an apparatus includes an electronic device including: a die or package; a thermal solution coupled with the die or package for cooling of the die or package; and ferromagnetic material, wherein the ferromagnetic material is to generate induction heating of the die or package in response to an alternating magnetic field.
Electronic device for heating an integrated structure, for example an MOS transistor
An electronic device includes an integrated circuit with a MOS transistor and a heating circuit electrically coupled to at least two points of one of the source or drain semiconductive region of the transistor. A portion of the source or drain semiconductive region between the two points forms a resistive element. The heating circuit is configured to cause a current to circulate through the resistive element between the two points to heat an active region of the transistor.

A vibration device has a substrate including a first surface and a second surface located on an opposite side to the first surface, a heater provided on the first surface side of the substrate, a temperature sensor provided on the first surface side of the substrate, a vibration element disposed on the first surface side of the substrate, a lid including a third surface joined on the first surface side and a fourth surface located on an opposite side to the third surface, and a circuit provided on one of the first surface, the second surface and the fourth surface, and including a temperature control circuit configured to control the heater based on an output of the temperature sensor.
Method to match SOI transistors using a local heater element
An integrated circuit with a matched transistor pair with a matching resistance heater coupled to each transistor of the matched transistor pair. A method for forming a matching resistance heater. A method for operating an SOI integrated circuit containing a matched transistor pair with a matching resistance heater coupled to each transistor of the matched transistor pair.
Phonon-recycling light-emitting diodes
Contrary to conventional wisdom, which holds that light-emitting diodes (LEDs) should be cooled to increase efficiency, the LEDs disclosed herein are heated to increase efficiency. Heating an LED operating at low forward bias voltage (e.g., V<k.sub.BT/q) can be accomplished by injecting phonons generated by non-radiative recombination back into the LED's semiconductor lattice. This raises the temperature of the LED's active rejection, resulting in thermally assisted injection of holes and carriers into the LED's active region. This phonon recycling or thermo-electric pumping process can be promoted by heating the LED with an external source (e.g., exhaust gases or waste heat from other electrical components). It can also be achieved via internal heat generation, e.g., by thermally insulating the LED's diode structure to prevent (rather than promote) heat dissipation. In other words, trapping heat generated by the LED within the LED increases LED efficiency under certain bias conditions.
CHIP HEATER AND HEATING AID ARRANGEMENT
A chip heater and heating air arrangement includes a circuit module including a circuit board, chip unit mounted on the circuit board and locating member mounted around the chip unit, heating aid including flat heat-transfer base panel, locating structure mounted in the flat heat-transfer base panel and attached to the chip unit and mounting structure outwardly extended from the flat heat-transfer base panel and fastened to the locating member, heater fastened to the locating structure of the heating aid, and heat dissipating mechanism including a heat-transfer holder plate attached to the heater. If the temperature of the chip unit goes below 0° C., the heater is turned on to generate heat and enabling generated heat to be transferred through the heating aid to heat the chip unit to the normal operating temperature level, enabling the computer device that uses the chip heater and heating air arrangement to work under cold environment.
