Abstract:
1. An LED device, comprising: a first type semiconductor layer; a light-emitting layer disposed on the first type semiconductor layer; a second type semiconductor layer disposed on the light-emitting layer, wherein the second type semiconductor layer and the light-emitting layer have truncated portions along a side surface of the second type semiconductor layer and a side surface of the light-emitting layer, the truncated portions having an exposed surface of the first type semiconductor layer; a first electrode pad having upper and sidewall surfaces, disposed on one of the first type semiconductor layer, the light-emitting layer, and the second type semiconductor layer, for an external electrical connection of the LED device; and a phosphor layer, which converts primary light emitted from the light-emitting layer to light of one or more different wavelengths, overlying an area of the second type semiconductor layer and the exposed surface of the first type semiconductor layer in the truncated portions, other than the upper surface of the first electrode pad, wherein the phosphor layer is not disposed on a side surface of the truncated portions, the side surface of the truncated portions extending between a top surface of the first type semiconductor layer and a top surface of the second type semiconductor layer.
