Abstract:
1. A surface mounted LED structure of integrating functional circuits on a silicon substrate, comprising the silicon substrate and an LED chip, wherein said silicon substrate has an upper surface of planar structure and without grooves, an oxide layer covers the upper surface of the silicon substrate, two metal electrode layers for connecting positive and negative electrodes respectively, are arranged in the upper surface of the oxide layer and insulated from each other, and the upper surfaces of said metal electrode layers are arranged with metal bumps respectively; the LED chip is flip-chip mounted to the silicon substrate and has positive and negative electrodes respectively connected to two metal bumps and thus to the metal electrode layers; two conductive metal pads are respectively arranged on the lower surface of said silicon substrate, said conductive metal pads are electrically connected to the metal electrode layers on the upper surface of the silicon substrate by a metal lead arranged on the side wall of the silicon substrate, and a heat conduction metal pad is arranged on the corresponding lower surface of the silicon substrate just below the LED chip; peripheral functional circuits required by LED are integrated on the upper surface of said silicon substrate, which are electrically connected to the metal electrode layers by a contact hole through the oxide layer.
