Claim Text:
1. A manufacturing process of a MEMS device, comprising: providing a first substrate comprising at least one first circuit disposed on a surface of the first substrate; providing a second substrate having a first surface and a second surface; disposing the second substrate on the surface of the first substrate with the first surface facing towards the first substrate; forming a trench in the second substrate and filling a dielectric material in the trench so as to divide the second substrate into a component region and a conducting part, wherein the component region and the conducting part are electrically isolated from each other; forming a conductive layer on the second surface of the second substrate; patterning the conductive layer so as to form a second circuit, wherein the second circuit is disposed upon and electrically isolated with both the component region and the conducting part, and electrically connected with at least the first circuit through a conducting via penetrating the first surface and the second surface of the conducting part; forming a MEMS component in the component region of the second substrate; providing a third substrate having a recessed region and a plurality of standoff structures; and disposing the third substrate over the second substrate, and connecting the standoff structures and the first substrate such that the second substrate is enclosed in the recessed region.
