Abstract:
1. A semiconductor structure, comprising: a semiconductor material having a first boundary and a second boundary, wherein the first boundary is parallel to, or substantially parallel to, the second boundary; a dielectric region, wherein at least a first portion of the dielectric region extends a distance of at least about one micron or greater from the first boundary of the semiconductor material toward the second boundary of the semiconductor material; wherein the first portion of the dielectric region comprises a first protrusion and a second protrusion spaced apart from the first protrusion; wherein the first protrusion has a first portion and a second portion and the second protrusion has a first portion and a second portion; and a capping material formed on the first protrusion and the second protrusion; wherein the first portion of the first protrusion is spaced apart from the first portion of the second protrusion by a first distance external to the capping material, the second portion of the first protrusion is spaced apart from the second portion of the second protrusion by a second distance external to the capping material, the second distance is substantially less than the first distance, and the first distance is more than about one hundred fifty percent (150%) of the second distance.
