Abstract: A miniature oxygen sensor makes use of paramagnetic properties of oxygen gas to provide a fast response time, low power consumption, improved accuracy and sensitivity, and superior durability. The miniature oxygen sensor disclosed maintains a sample of ambient air within a micro-channel formed in a semiconductor substrate. O2 molecules segregate in response to an applied magnetic field, thereby establishing a measureable Hall voltage. Oxygen present in the sample of ambient air can be deduced from a change in Hall voltage with variation in the applied magnetic field. The magnetic field can be applied either by an external magnet or by a thin film magnet integrated into a gas sensing cavity within the micro-channel. A differential sensor further includes a reference element containing an unmagnetized control sample. The miniature oxygen sensor is suitable for use as a real-time air quality monitor in consumer products such as smart phones.

Abstract: The present disclosure is directed to a gas sensor device that includes a plurality of gas sensors. Each of the gas sensors includes a semiconductor metal oxide (SMO) film, a heater, and a temperature sensor. Each of the SMO films is designed to be sensitive to a different gas concentration range. As a result, the gas sensor device is able to obtain accurate readings for a wide range of gas concentration levels. In addition, the gas sensors are selectively activated and deactivated based on a current gas concentration detected by the gas sensor device. Thus, the gas sensor device is able to conserve power as gas sensors are on when appropriate instead of being continuously on.

Abstract: Miniature resistive gas detectors incorporate thin films that can selectively identify specific gases when heated to certain characteristic temperatures. A solid state gas sensor module is disclosed that includes a gas sensor, a heater, and a temperature sensor, stacked over an insulating recess. The insulating recess is partially filled with a support material that provides structural integrity. The solid state gas sensor module can be integrated on top of an ASIC on a common substrate. With sufficient thermal insulation, such a gas detector can be provided as a low-power component of mobile electronic devices such as smart phones. A method of operating a multi-sensor array allows detection of relative concentrations of different gas species by either using dedicated sensors, or by thermally tuning the sensors to monitor different gas species.

Abstract: An electronic device is formed by depositing polyimide on a glass substrate. A conductive material is deposited on the polyimide and patterned to form electrodes and signal traces. Remaining portions of the electronic device are formed on the polyimide. A second polyimide layer is then formed on the first polyimide layer. The glass substrate is then removed, exposing the electrodes and the top surface of the electronic device.

Abstract: An integrated circuit is formed having an array of memory cells located in the dielectric stack above a semiconductor substrate. Each memory cell has two adjustable resistors and two heating elements. A dielectric material separates the heating elements from the adjustable resistors. One heating element alters the resistance of one of the resistors by applying heat thereto to write data to the memory cell. The other heating element alters the resistance of the other resistor by applying heat thereto to erase data from the memory cell.
