20120217608 | THERMOELECTRIC DEVICE USING SEMICONDUCTOR TECHNOLOGY - An integrated thermoelectric device in semiconductor technology comprising a hot side arranged in proximity to a heat source, and a cold side, providing a signal according to the temperature difference between the hot and cold sides. The hot and cold sides are arranged in such a way that their temperatures tend to equal out when the temperature of the heat source varies, i.e. when the sensor is in poor operating conditions. A measuring circuit provides useful information according to a continuously variable portion of the signal from a time when the temperature of the heat source varies. If the temperature of the heat source ceases to vary, the temperatures of the hot and cold sides eventually equal out and the signal is annulled and ceases to vary. The distance between the hot and cold sides can be less than 100 μm. | 08-30-2012 |

20140015089 | DIFFERENTIAL TEMPERATURE SENSOR AND ITS CAPACITORS IN CMOS/BICMOS TECHNOLOGY - The sensor is made on a semiconductor substrate covered with an electrically insulating layer. The electrically insulating layer separates a thermocouple from the substrate. It includes a first portion presenting a first value of capacitance per unit area and a second portion presenting a second value of capacitance per unit area, which is lower than the first value. The sensor includes first and second output terminals connected to the thermocouple. The first output terminal includes a first capacitor having a first electrode formed by a first leg made of an electrically conducting material. The second electrode of the capacitor is formed by a part of the substrate facing said first leg and separated from the first electrode by the first portion of the electrically insulating layer. The first leg connects the thermocouple while overlapping the second portion of the electrically insulating layer. | 01-16-2014 |
