Patent ID: 8238401

Claim:
An apparatus, comprising: a silicon-based support plate having a first primary surface and a second primary surface opposite the first primary surface; a silicon-based first fin structure extending outward from the first primary surface of the support plate and having a first primary surface, a second primary surface opposite the first primary surface, and a plurality of edges between the first and the second primary surfaces including a first edge and a second edge opposite the first edge; and a silicon-based second fin structure extending outward from the first primary surface of the support plate and having a first primary surface, a second primary surface opposite the first primary surface, and a plurality of edges between the first and the second primary surfaces including a first edge and a second edge opposite the first edge, wherein the respective second edge of at least one of the first fin structure and the second fin structure comprises a V-shaped wedge, wherein the second edge of the first fin structure and the second edge of the second fin structure have different heights with respect to the first primary surface of the support plate when the first edge of the first fin structure and the first edge of the second fin structure are received on the first primary surface of the support plate, and wherein the support plate includes at least a first V-notch groove and a second V-notch groove on the first primary surface of the support plate, wherein the first fin structure is mounted on the support plate with the first edge of the first fin structure received in the first V-notch groove of the support plate, and wherein the second fin structure is mounted on the support plate with the first edge of the second fin structure received in the second V-notch groove of the support plate.
