A method for fabricating an integrated AC LED module comprises steps: forming a junction layer on a substrate, and defining a first growth area and a second growth area on the junction layer; respectively growing a Schottky diode and a LED on the first growth area and the second growth area; forming a passivation layer and a metallic layer on the Schottky diode, the LED and the substrate. Thereby, the Schottky diode is electrically connected with the LED via the metallic layer. Thus is promoted the reliability of electric connection of diodes, reduced the layout area of the module, and decreased the fabrication cost.
