Light emitting element and method of making the same
First Claim
1. A flip-chip type light emitting element, comprising:
- a spreading electrode for feeding current to a light-emitting layer, the spreading electrode comprising an extended part extending in a predetermined direction;
a plurality of intermediate electrodes formed on the spreading electrode and arranged in a longitudinal direction of the extended part and centrally in a width direction of the extended part;
an insulating layer formed on the spreading electrode and on the plurality of intermediate electrodes; and
a joining electrode formed on the insulating layer for feeding current through the plurality of intermediate electrodes to the spreading electrode,wherein the plurality of intermediate electrodes are disposed such that a distance of half a pitch thereof in the longitudinal direction is equal to or shorter than a distance measured in the width direction from one of the plurality of intermediate electrodes to an edge of the extended part.

Abstract
A light emitting element includes a first electrode, a second electrode formed on a same side as the first electrode and including an area less than the first electrode, a first bump formed on the first electrode, and a second bump formed on the second electrode and including a level at a top thereof higher than that of the first bump. A flip-chip type light emitting element includes a spreading electrode, the spreading electrode including an extended part, and plural intermediate electrodes formed on the spreading electrode and arranged in a longitudinal direction of the extended part and centrally in a width direction of the extended part. The intermediate electrodes are disposed such that a distance of half a pitch thereof in the longitudinal direction is equal to or shorter than a distance from one of the intermediate electrodes to an edge of the extended part.
