Patent ID: 7015533

Claim:
A semiconductor construction, comprising: a semiconductor substrate; a silicon-containing conductive node supported by the semiconductor substrate; a first conductive material physically against a surface of the conductive node and shaped as a container, the container having an opening defined thereby; the first conductive material comprising one or more of platinum, rhodium, iridium, ruthenium, titanium, tantalum, and tungsten; a first insulative material within the container opening; a second conductive material over the container opening and physically against a surface of the container; the second conductive material comprising one or more of platinum, rhodium, iridium, ruthenium, titanium, tantalum, and tungsten; and a second insulative material over the second conductive material; the second insulative material being selected from the group consisting of aluminum oxide, tantalum oxide, BST, PZT, PLZT, and mixtures thereof.
