Abstract
An integrated temperature sensor comprises a chip package enclosing an integrated circuit and an ultrasonic transceiver which is integrated on top of the integrated circuit. The ultrasonic transceiver comprises a transmitting element which is arranged for emitting ultrasound waves, and a receiving element which is arranged for receiving ultrasound waves. The chip package comprises at least one barrier arranged at a defined position in the chip package. The barrier is designed to at least partly reflect ultrasound waves emitted by the transmitting element towards the receiving element. The integrated circuit comprises an actuator element to actuate the transmitting element to emit ultrasound waves according to a first signal s(t), and a converter element to convert an ultrasound wave, received by the receiving element, into a second signal y(t). Furthermore, a method for producing an integrated temperature sensor and a method for determining a temperature by means of an integrated temperature sensor are presented.
