Patent ID: 7592633

Claim:
A semiconductor light emitting device comprising: a substrate; a semiconductor lamination portion formed on the substrate by laminating semiconductor layers so as to form a light emitting layer; an insulating layer or a semi-insulating layer provided on a substrate side of the semiconductor lamination portion, the insulating layer or the semi-insulating layer being a part of the substrate or a layer deposited on the substrate; a plurality of light emitting units formed by separating the semiconductor lamination portion by a first separating groove which reaches to the insulating layer or the semi-insulating layer to form electrically isolated areas, each of the plurality of light emitting units being encircled by said first separating groove having a pair of electric connecting portions which are connected to a pair of p-type and n-type conductivity layers of the semiconductor lamination portion respectively; and wiring films which are connected to the electric connecting portions for connecting each of the plurality of light emitting units in series and/or parallel, wherein at least one of the plurality of light emitting units encircled respectively by the first separating groove are encircled by a second separating groove which reaches to the insulating layer or the semi-insulating layer and is formed outside of the first separating groove and sufficiently distant therefrom so as to separate electrically the semiconductor lamination portion, and wherein each of the first and second separating grooves has a width of 0.6 μm to 5 μm and an insulating film is filled in an inside of at least a surface side of the groove, and at least one of the wiring films pass on the insulating film through the first and second separating grooves.
