More Information
Summary:The present invention relates to a light emitting device having composite substrate, and includes the followings: one composite substrate, which contains one high heat conduction layer and the substrate surrounding at the periphery of the high heat conduction layer; a bonding layer formed on the composite substrate; and a light-emitting stack layer formed on the bonding layer. Thus it is capable of solving the difficulty of cutting metal layer when cutting to form the dice.
