Abstract
A light-emitting device comprises: a supporting member having a top surface with a first surface area and a bottom surface with a second surface area; a first conductive via having a top surface with a third surface area; a second conductive via separated from the first conductive via and having a top surface with a fourth surface area, wherein the supporting member surrounds the first conductive via and the second conductive via; and a semiconductor structure comprising an active layer on the supporting member; wherein the sum of the third surface area and the fourth surface area is greater than 40% of the first surface area and smaller than the first surface area.
