Patent ID: 8048225

Claim:
A method for fabricating crystalline material comprising: providing an seed structure substrate having a length x, a width y, and a thickness z, where x>y and x>z, the seed structure having a first surface on one side defined by length x and width y, and a second surface on an opposite side also defined by length x and width y; forming crystalline material on the first surface and on the second surface, thereby resulting in a an seed structure substrate having a layer of crystalline material approximately of length x and width y, and having thickness t overlying each the first surface and the second surface; forming laterally grown regions of the crystalline material of approximately thickness t, the laterally grown regions not overlying the seed structure substrate, and extending away from the seed structure in a direction parallel to the width y direction from the crystalline material; then removing at least a portion of the crystalline material to form a piece of crystalline material separate from the seed structure substrate.
