Abstract:
A semiconductor device includes a tube-like structure comprising a plurality of dielectric layers and conductor layers that are disposed on top of one another; a conductor tip integrally formed with a cap conductor layer that is disposed on a top surface of the tube-like structure, wherein the conductor tip extends to a central hole of the tube-like structure; and at least one photodetector formed within a bottom portion of the tube-like structure.

Claim (Index 17):
A method of forming a semiconductor device, comprising:\n providing a substrate overlaid by a first sacrificial layer; forming a plurality of photodetectors in a bottom dielectric layer, wherein the bottom dielectric layer is disposed over the first sacrificial layer; farming a top conductor layer that is disposed on a plurality of intermediate dielectric and conductor layers over the bottom dielectric layer; forming a shallow trench in the top conductor layer; forming a deep trench coupled to the shallow trench, wherein the deep trench extends through the plurality of intermediate dielectric and conductor layers and the bottom dielectric layer; refilling the shallow and deep trenches with a second sacrificial layer so as to form a concave cusp on a top surface of the second sacrificial layer; etching the second sacrificial layer to further extend the concave cusp; refilling the concave cusp with a cap conductor layer so as to form a conductor tip in the concave cusp; removing the substrate; and removing the first and second sacrificial layers to expose the deep trench and part of the shallow trench so as to cause the conductor tip to be in the deep trench.
