Claim Text:
1. A structure comprising: a semiconductor; a capacitor disposed on one surface portion of the semiconductor; a transistor device disposed on a second surface portion of the semiconductor; wherein the capacitor comprising: wherein a first one of the transistor device electrodes is separated from a second one of the transistor device electrodes by a first portion of a device dielectric and the second one of the transistor device electrodes is separated from a third one of the transistor device electrodes by a second portion of the device dielectric; wherein the first portion of the device dielectric and the second portion of the device dielectric are in direct contact with the semiconductor; wherein the capacitor dielectric and the device dielectric are the same material and have different thicknesses; and wherein the capacitor dielectric and the device dielectric have different hydrogen contents; and wherein an etch rate of the capacitor dielectric is at least fourteen to one greater than an etch rate of the device dielectric to the same etchant.
