Patent ID: 7956380

Claim:
An InGaN-based semiconductor light-emitting device comprising: an epitaxial growth semiconductor layer formed by depositing a first growth layer on a substrate, forming a mask on the first growth layer that includes a plurality of apertures defining exposed portions of the first growth layer, continuing growth of the first growth layer on the exposed portions to form a low dislocation density second growth layer defining a top surface of the epitaxial growth semiconductor layer including dislocations bent in an in-plane direction of the epitaxial growth semiconductor layer, the epitaxial growth semiconductor layer having a bottom surface opposite to the top surface and formed by removing the mask and the substrate from the epitaxial growth semiconductor layer such that the epitaxial growth semiconductor layer consists of the second growth layer including said bent dislocations; an n-type cladding layer formed on the top surface of the epitaxial growth semiconductor layer; an active layer formed on the n-type cladding layer; a p-type cladding layer made of GaN and formed on the active layer; a p-side Ag electrode formed on the p-type cladding layer; and an n-side electrode formed on the bottom surface of the epitaxial growth semiconductor layer, wherein the entire p-type cladding layer and the epitaxial growth semiconductor layer have a dislocation density less than about 1×10 6 (1/cm 2 ), and wherein a diameter or a length of a side of a planar dimension of said light-emitting device is less than about 20 μm.
