ABSTRACT:
A method for forming an array of single crystalline seed crystals separated by an insulator and suitable for use in the formation of infrared detector elements is disclosed. The seed crystals are formed from a single crystalline substrate having first and second planar surfaces. An array of grooves is formed in the first planar surface of the single crystalline substrate such that a plurality of protrusions are formed upon the first planar surface of the single crystalline substrate. The grooves are then filled with an insulator. A portion of the second planar surface of the substrate is then removed to expose the insulator disposed within the grooves to form an array of single crystalline seed crystals. The single crystalline seed crystals are separated by the insulator. The single crystalline seed crystals and the insulator are exposed upon both the first and second surfaces of the array.
