Abstract
A vertical solid state lighting (SSL) device is disclosed. In one embodiment, the SSL device includes a light emitting structure formed on a growth substrate. Individual SSL devices can include a embedded contact formed on the light emitting structure and a metal substrate plated at a side at least proximate to the embedded contact. The plated substrate has a sufficient thickness to support the light emitting structure without bowing.
Claims13
A wafer having a plurality of individual solid state lighting devices, comprising:
- a light emitting structure having a first side and a second side opposite the first side, the light emitting structure comprising a first semiconductor material on the first side, a second semiconductor material on the second side, and an active region between the first and second semiconductor materials;
- an embedded contact at the second side;
- a plated substrate formed on the embedded contact, wherein the plated substrate has a thickness sufficient to inhibit bowing of the light emitting structure;
- and
- a plurality of exterior contacts formed on the first side of the light emitting structure, wherein the wafer is at least approximately 150 millimeters in diameter.
