METHOD FOR MANUFACTURING SUBSTRATE FOR LIGHT-EMITTING ELEMENT, SUBSTRATE FOR LIGHT-EMITTING ELEMENT, AND LIGHT-EMITTING DEVICE

摘要

Provided is a method for manufacturing a substrate for a light-emitting element with high heat dissipation. The method for manufacturing the substrate for a light-emitting element has a first step for manufacturing a ceramic substrate having a first metal conductor layer and also having a plating-hole section extending from the first metal conductor layer to the main surface, and a second step for forming a second metal conductor layer on the plating hole section using electroplating to make the first metal conductor layer into a cathode.
