Patent ID: 7586962

Claim:
Laser diode array apparatus comprising: a sacrificial substrate member, of first material composition, having a generally planar upper working surface with an ordered array of working surface indentations received therein; a first sub array of said sacrificial substrate working surface indentations comprising a plurality of parallel rows of elongated flat bottomed recessions extending across a substantial two dimensional working surface portion; a second sub array of said sacrificial substrate working surface indentations comprising plurality of parallel rows of elongated sloping cross sectional recessions of greater depth and cross sectional area than said first array indentations and of intermediate parallel location with respect to said first array indentations; each element in said second sub array of said sacrificial substrate working surface indentations including a sacrificial substrate member material crystal plane determined laser energy reflection surface, and; a deposited layer of electrically insulating thermally conductive laser diode array carrier structure-composing second material disposed over said sacrificial substrate member generally planar upper working surface and into a filling and conformed relationship with said first and second sub array working surface indentations; wherein said layer of thermally conductive laser diode array carrier structure-composing second material is comprised of a layer of diamond material; wherein said sacrificial substrate member of first material composition is comprised of semiconductor material, and; wherein said second sub array of said sacrificial substrate working surface indentations include sloping cross sectional portions aligning with a 111 crystal plane of said semiconductor material.
