Classification: CPC H | IPC H

Claim 12:
13. A method of forming a semiconductor device, the method comprising:
providing a plurality of vertical structures and a plurality of trenches;
forming a first portion of a dielectric bridge by delivering a dielectric material at a first non-zero angle of inclination relative to a normal extending perpendicular from a top surface of the plurality of vertical structures, wherein the dielectric bridge extends over at least one trench of the plurality of trenches; and
forming a second portion of the dielectric bridge by delivering the dielectric material at a second non-zero angle of inclination relative to the normal extending perpendicular from the top surface of the plurality of vertical structures, wherein the second portion of the dielectric bridge is connected to the first portion of the dielectric bridge, wherein the dielectric bridge partially defines a cavity within the at least one trench of the plurality of trenches, and wherein the cavity is beneath the dielectric bridge.
