Claim 0:
1. A microelectromechanical system (MEMS) device, comprising:
a substrate; and
a MEMS force sensor mounted on the substrate, the MEMS force sensor comprising:
a sensor die configured to receive an applied force, the sensor die comprising a first substrate and a second substrate, wherein at least a portion of the second substrate defines a deformable membrane;
a cavity formed in the first substrate;
a sensing element on a surface of the second substrate, the sensing element operable to convert a strain on the surface of the second substrate to an analog electrical signal that is proportional to the strain;
a protective layer at least partially covering the surface of the second substrate; and
a conductive pad on the protective layer and electrically coupled to the sensing element, wherein:
the MEMS force sensor is mounted on the substrate using an under bump metal (UBM) layer that is on the conductive pad and an electrical connector that is between the UBM layer and the substrate; and
the conductive pad is electrically coupled to the substrate through the UBM layer and the electrical connector.
