Abstract:
A microelectromechanical systems (MEMS) device and a method for calibrating a MEMS device. The device includes a first semiconductor substrate including at least one MEMS component. The device also includes an application specific integrated circuit (ASIC) comprising a second semiconductor substrate. The second semiconductor substrate is attached to the first semiconductor substrate. The second semiconductor substrate includes at least one piezoresistive strain gauge. Each piezoresistive strain gauge includes at least one doped semiconductor region having a resistivity that is determined by a strain on said doped semiconductor region. The second semiconductor substrate also includes a circuit for evaluating a trim algorithm for the at least one MEMs component using one or more output values received from the at least one piezoresistive strain gauge.
