Patent ID: 8053899

Claim:
A semiconductor device structure, comprising: at least one conductive structure on a semiconductor substrate; at least one insulative structure on the semiconductor substrate, laterally adjacent to the at least one conductive structure; a first insulative material over the at least one conductive structure and the at least one insulative structure; at least one first trench in the first insulative material, the at least one first trench: at least partially lined with a second insulative material; substantially filled with a conductive material located at a higher elevation than the at least one insulative structure and the at least one conductive structure; and including an insulative cap over the conductive material, the insulative cap comprising a third insulative material, the first insulative material comprising a different material than the second and third insulative materials; and at least one second trench in the first insulative material, the at least one second trench electrically isolated from the at least one first trench only by the second insulative material.
