Title:
EPITAXIAL SUBSTRATE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/087806
Kind Code:
A1
Abstract:
Disclosed are an epitaxial substrate. The epitaxial substrate comprises: a substrate body; a plurality of bosses arranged on the substrate body in an array manner; a plurality of contact electrodes correspondingly arranged on the top of the bosses; a planarization layer covering the bosses and a region of the substrate body that is not covered by the bosses, wherein the planarization layer is provided with first through holes corresponding to the bosses so that the contact electrodes are exposed via the first through holes; and a plurality of pads arranged in an array manner on the planarization layer and electrically connected to the corresponding contact electrodes via the first through holes, wherein the area of vertical projection of the pad on the substrate body is greater than the area of vertical projection of the contact electrode on the substrate body. Further disclosed is a method for manufacturing an epitaxial substrate. By means of the method, the present application can improve the alignment success rate between an epitaxial substrate and a driving substrate.
