Assignee: MIKRO MESA TECHNOLOGY CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A device, comprising:
a substrate having a top surface;
a first conductive pad and a second conductive pad on the substrate;
a light-emitting diode on the first conductive pad;
a metal protrusion on the second conductive pad, wherein the metal protrusion is in direct contact with the second conductive pad;
a polymer layer covering the top surface of the substrate, the first conductive pad, and the second conductive pad and surrounding the metal protrusion and the light-emitting diode, wherein a distance from a top of the metal protrusion to the top surface of the substrate is greater than a thickness of the polymer layer, and a bottom surface of the metal protrusion is lower than a top surface of the polymer layer; and
a top electrode covering the light-emitting diode, the polymer layer, and the metal protrusion such that the light-emitting diode is electrically connected with the second conductive pad, wherein a distance between a top surface of a portion of the top electrode overlying the metal protrusion to the top surface of the substrate is greater than a distance between a top surface of another portion of the top electrode free from overlapping with the metal protrusion and the light-emitting diode to the top surface of the substrate.
