    摘要: A first device region (10) of one conductivity type adjacent one major surface (1a) of a semiconductor body (1) has a relatively highly doped subsidiary region (11) spaced from the one major surface (1a) by a relatively lowly doped subsidiary region (12). A second device region (20) of the opposite conductivity type within the subsidiary region (12) has an intrinsic subsidiary region (21) and an extrinsic subsidiary region (23,24) surrounding the intrinsic subsidiary region (21) forming respective first and second pn junctions (22,25) with the relatively lowly doped subsidiary region (12). A third device region (30) of the one conductivity type is formed within the intrinsic subsidiary region (21) surface (1a). An additional region (60,60',61,62) is provided beneath the extrinsic subsidiary region (23,24) so as to lie within the spread of the depletion region (250) associated with the second pn junction (25) when the first and second pn junction (22,25) are reverse-biassed thereby extending the depletion region (250) beneath the emitter region (30) to cause an increase in the Early voltage (V.sub.eaf) of the device.

    摘要: The invention relates to a sensor (102) and a control unit (702) for cooperation with the sensor. The sensor (102) serves for measuring a velocity of a fluid (308) flowing through a channel (306). The sensor (102) employs a thermal measuring principle, which measuring principle is robust regarding disturbances on the amount of power dissipated by the heating element (106). A sensor receiver (110) is arranged for receiving an electromagnetic radiation generated by a control transmitter (722) comprised in a control (702) unit for cooperation with the sensor (102). The electromagnetic radiation is employed for powering the heating element (106) which is arranged for heating the fluid. On the basis of a measurement signal generated by a transducer arrangement comprised in the sensor (102), a control actuator (724) controls the velocity of the fluid. For this purpose a sensor transmitter (116) is arranged for transmitting the measurement signal to a control receiver (734).
