Abstract:
A method for fabricating an integrated circuit, the method comprising:(a) providing a body having one or more openings in a first side; (b) fabricating a first dielectric and a conductor in each of the one or more openings with the conductor in each of the openings being separated from the body by the first dielectric; (c) removing material of the body from a second side of the body to expose the first dielectric on the second side, wherein when the first dielectric becomes exposed on the second side, the first dielectric covers the conductor on the second side so that the conductor is not exposed on the second side; (d) after the first dielectric has been exposed on the second side, removing the material of the body and the first dielectric from the second side to expose the conductor in each of the openings, wherein the removing of the material of the body and the first dielectric comprises a process in which the removal rate of the first dielectric is lower than the removal rate of material of the body; wherein the body comprises a transistor and/or a capacitor.
