    摘要: The present invention relates to a silicon pressure sensor that in need of three strips of piezoresistors on each side and the manufacturing method thereof; wherein, the impurity concentration of the piezoresistors are about 1019-1020 cm−3 in order to reduce the influence of temperature; the lead between the piezoresistors (namely the internal connection lead) is a highly-doping interconnect (about 1021 cm−3) fabricated along the direction with minimum piezoresistance coefficient; with regard to the connection circuit for connecting the piezoresistors with the external Wheatstone bridge circuit (namely the external connection circuit), of which one end near the inner side of the membrane is also fabricated along the direction with minimum piezoresistance coefficient, and another end of the lead near the edge of the membrane is a interconnect that is perpendicular to the diaphragm, and is connected out to the external circuit; with this structure, the four resistors of the Whetstone bridge are balanced and symmetrized, thus the zero offset caused by the variations in resistance of the bridge can be reduced in order to simplify the signal-processing circuit.

    摘要: A portable electronic device adapted to be detachably connected to a cradle having a containing cavity is provided, wherein an inner wall of the containing cavity has a recess. The portable electronic device includes a body and a locking-and-releasing mechanism disposed in the body and including a driving unit and a latch. The driving unit is disposed in the body. The latch is connected to the driving unit and suitable for being driven by the driving unit to protrude out of the body or hide in the body. When the portable electronic device is disposed in the containing cavity, the driving unit drives the latch to protrude out of the body and be engaged with the recess. When the portable electronic device is going to be detached from the containing cavity, the driving unit drives the latch to be disengaged from the recess and move back in the body.

    摘要: A method of making a silicon-based miniaturized microphone by means of the application of a combination of processes including a semiconductor manufacturing process and a silicon micro-machining technology. A silicon-based miniaturized microphone made by means of this method has a silicon substrate, which defines a resonance cavity, a diaphragm, a backplate having sound holes, and solder pads. This method is easy to perform, and suitable for a mass production to reduce the manufacturing cost.
