Abstract:
A vertical type light emitting diode die and a method for fabricating the same is disclosed. A growth substrate is provided and an epitaxial layer is formed on the growth substrate. A metallic combined substrate is connected to the epitaxial layer. Then, the growth substrate is removed. Electrode units are formed on the top surface of the epitaxial layer. The epitaxial layer is divided into epitaxial dies according to the number of the plurality of electrode units. Each vertical type light emitting diode die formed in the abovementioned way includes the metallic combined substrate having a first metal layer and second metal layers. The first metal layer is combined with the two second metal layers by cutting, vacuum heating, and polishing, so as to enable the metallic combined substrate to have a high coefficient of thermal conductivity, a low coefficient of thermal expansion, and initial magnetic permeability.

Claim (Index 1):
A method for fabricating a vertical type light-emitting diode die comprising:\n providing a growth substrate and forming an epitaxial layer on the growth substrate; providing a metallic combined substrate formed by cutting, vacuum heating, and polishing, the vacuum heating is performed on the metallic combined substrate under 100\u02dc250 ton at 150\u02dc250 \u00b0 C. for 10\u02dc30 min, and the metallic combined substrate further comprises a first metal layer and two second metal layers respectively formed on a top surface and a bottom surface of the first metal layer; forming a connecting metal layer on the metallic combined substrate and connecting the metallic combined substrate to the epitaxial layer through the connecting metal layer, and one of the two second metal layer is located between the epitaxial layer and the first metal layer; removing the growth substrate; forming a plurality of electrode units on a top surface of the epitaxial layer; and dividing the epitaxial layer into a plurality of epitaxial dies on the metallic combined substrate according to number of the plurality of electrode units.
