Title: Semiconductor template substrate, light-emitting device using a semiconductor template substrate, and manufacturing method therefor

Abstract: A light-emitting device includes a semiconductor layer, a light-emitting stack structure formed on a first surface of the semiconductor layer, and a plurality of inverted pyramid structures formed on a second surface of the semiconductor layer opposite to the first surface. Each of the inverted pyramid structures has a sectional area increasing as each of the inverted pyramid structures is more extended in a vertical direction from the second surface.
