1. A light-emitting device, comprising:a substrate;
a semiconductor structure disposed on the substrate, the semiconductor structure having an active region disposed between an n-type layer and a p-type layer;
a wavelength converter formed above the substrate;
an insulating side coating formed around the semiconductor structure; and
a reflective side coating formed around the wavelength converter and the substrate, the reflective side coating being stacked over the insulating side coating, the reflective side coating having a top surface that is flush with a top surface of the wavelength converter, and the reflective side coating having a bottom surface that is disposed above a top surface of the insulating side coating.
