Claim Text:
1. A MEMS device having a structure comprising: a first sheet of a semiconductor substrate having a first surface and a second surface; first vertical holes extending from the first surface through the first semiconductor substrate to the second surface, wherein: first electrical conductors extending inside the holes from the first opening to the second opening; a second sheet of a semiconductor substrate having a third surface and a fourth surface, the second sheet overlying the first sheet, such that the third surface is adjacent to the first surface; second vertical holes extending from the third surface through the second semiconductor substrate to the fourth surface, opposite to the first surface, wherein: second electrical conductors extending inside the second vertical holes from the third opening to the fourth opening; a device substrate electrically connected to the second openings at the second surface; an electrode pad formed on the fourth surface; and a junction layer connecting the first electrical conductors and the second electrical conductors, such that the device substrate is electrically connected to the electrode pad via the first electrical conductors, the junction layer, and the second electrical conductors.
