III-Phospide and III-Arsenide flip chip light-emitting devices

An array of light-emitting devices comprising:

• a substrate having a surface;
• and
• a plurality of light-emitting semiconductor devices, each of which comprises a stack of semiconductor layers including an active region, a superstrate disposed on a first side of said stack and substantially transparent to light emitted by said active region, and a first electrical contact and a second electrical contact disposed on a second side of said stack opposite to said first side, said light-emitting semiconductor devices disposed above said surface of said substrate with their superstrates facing away from said substrate;
• wherein said active regions of at least a subset of said light-emitting semiconductor devices include a semiconductor selected from the group consisting of III-Phosphides, III-Arsenides, and alloys thereof.

A light-emitting semiconductor device comprising:

• a stack of layers including an active region, said active region comprising a semiconductor selected from the group consisting of III-Phosphides, III-Arsenides, and alloys thereof;
• a superstrate disposed on a first side of said stack, wherein said superstrate provides mechanical stability to the device and is substantially transparent to light emitted by said active region;
• and
• a first electrical contact and a second electrical contact electrically coupled to apply a voltage across said active region, said first electrical contact and said second electrical contact disposed on a second side of said stack opposite to said first side.
