Abstract
A light-emitting device includes a carrier substrate, a flip-chip light-emitting diode (LED) mounted onto the carrier substrate, and an electrode unit disposed between the carrier substrate and the flip-chip LED. The electrode unit includes first and second connecting electrodes that have opposite conductivity. Each of the first and second connecting electrodes includes an intermediate metal layer and a binding layer that are sequentially disposed on the flip-chip LED in such order. The binding layer includes a first portion being adjacent to the carrier substrate and forming an eutectic system with tin, and a second portion located between the first portion and the intermediate metal layer.
