Claim 12:
13. An integrated circuit, comprising:
a substrate; and
a plurality of platinum-containing conductive segments in a platinum-containing layer over the substrate, the plurality of platinum-containing conductive segments including first and second adjacent segments, the platinum-containing conductive segments having coplanar top surfaces and coplanar bottom surfaces, the bottom surfaces being closer to the substrate than are the top surfaces, and the bottom surfaces being wider than the top surfaces,
wherein:
the first and second conductive segments have a trapezoidal sectional profile such that a first spacing between the first conductive segment and the second conductive segment at the top surfaces is greater than a second spacing between the first conductive segment and the second conductive segment at the bottom surfaces;
a width of the first conductive segment along the top surface is less than twice a thickness of the first conductive segment;
the second spacing is less than twice the thickness of the first conductive segment;
a first platinum oxide layer is on the first conductive segment; and
a second platinum oxide layer is on the second conductive segment.
