Patent ID: 8227310

Claim:
A method of forming an integrated circuit, comprising: providing a semiconductor topography comprising an active transistor laterally adjacent to a trench capacitor formed in a semiconductor substrate, the active transistor comprising a source junction and a drain junction, wherein a barrier layer is disposed along a periphery of the trench capacitor for isolating the trench capacitor; forming an interlevel dielectric across the semiconductor topography; concurrently etching (i) a first opening through the interlevel dielectric to the drain junction of the active transistor and the trench capacitor, and (ii) a second opening through the interlevel dielectric to the source junction of the active transistor; and filling the first opening and the second opening with a conductive material to form a strap for electrically connecting the trench capacitor to the drain junction of the active transistor and to also form a contact for electrically connecting the source junction to an overlying level of the integrated circuit.
