Claim Text:
1. An integrated inertial sensor and pressure sensor, comprising: a first substrate comprising a first surface and a second surface opposite to the first surface, and the first substrate comprising a first region and a second region; at least one or more conductive layers, deposited on the first surface of the first substrate, wherein the at least one or more conductive layers comprises a first electrical shielding layer for the inertial sensor, and wherein the first electrical shielding layer is electrically connected to the first substrate through one or more vias with the one or more vias only between the first electrical shielding and the first substrate; a movable sensitive element of the inertial sensor, formed by using the first region of the first substrate; a second substrate and a third substrate, the second substrate being coupled to a surface of the conductive layer on the first surface of the first substrate, the third substrate being coupled to the second surface of the first substrate in which the movable sensitive element of the inertial sensor is formed, and the third substrate and the second substrate are respectively arranged on two opposite sides of the movable sensitive element of the inertial sensor; and a sensitive film of the pressure sensor, comprising at least the second region of the first substrate, or comprising at least one of the conductive layers on the second region of the first substrate.
