Title:
SEMICONDUCTOR LIGHT EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/189131
Kind Code:
A1
Abstract:
This semiconductor light emitting device comprises: a substrate that has a first principal surface on one side and a second principal surface on the other side; a plurality of via electrodes embedded in the substrate at intervals such that the occupying ratio with respect to the surface area of the first principal surface in plan view is 10%-60%; an electrode membrane collectively covering the plurality of via electrodes on the first principal surface; and a semiconductor light emitting chip disposed on the electrode membrane so as to face the plurality of via electrodes.
