Abstract:
This disclosure relates to a structure for aligning layers of an integrated circuit (IC) structure that may include a first dielectric layer positioned above a semiconductor substrate having one or more active devices, a trench stop layer positioned above the first dielectric layer, a second dielectric layer positioned above the trench stop layer, and a plurality of metal-filled marking trenches extending vertically through the second dielectric layer and the trench stop layer and at least partially into the first dielectric layer. The metal-filled trenches are electrically isolated from any active devices contained in the IC.

Claim (Index 1):
A structure for aligning layers of an integrated circuit (IC), the structure comprising:\n a first dielectric layer positioned above a semiconductor substrate, the semiconductor substrate having one or more active devices thereon; a trench stop layer positioned above the first dielectric layer; a second dielectric layer positioned above the trench stop layer; and a plurality of marking trenches extending vertically through the second dielectric layer and the trench stop layer, and at least partially into the first dielectric layer, wherein each of the plurality of marking trenches is filled solely with a metal, and the metal is electrically isolated from the one or more active devices by at least the first dielectric layer.
