Patent ID: 7943465

Claim:
A method for manufacturing a semiconductor component, comprising: providing a semiconductor material having a major surface; forming at least one trench in the semiconductor material, the at least one trench having a floor and sidewalls; forming at least one self-aligned landing pad over and laterally adjacent to the at least one trench, wherein forming the at least one self-aligned landing pad includes: forming a first layer of dielectric material over the major surface; forming a second layer of dielectric material over the first layer of dielectric material; forming a third layer of dielectric material over the second layer of dielectric material; forming an opening through the first, second, and third layers of dielectric material; and removing a portion of the second layer of dielectric material that is exposed by the opening extending through the first, second, and third layers of dielectric material to form cavities that extend laterally into the second layer of dielectric material.
