Patent ID: 7674641

Claim:
A method for fabricating a white-light-emitting flip-chip diode having silicon (Si) quantum dots, comprising: Step (a): Obtaining a transparent substrate; Step (b): Obtaining a film material having evenly embedded Si quantum dots of granular sizes between 1 and 10 nanometers formed through a chemical vapor deposition operated under a temperature between 100 and 1000 Celsius degrees, the evenly embedded Si quantum dots being evenly distributed throughout the film material; Step (c): Coating said transparent substrate with said film material having said Si quantum dots; and Step (d): Obtaining a flip-chip diode emitting an ultra blue-violet light coated with an adhesive on a light-extracting surface of said flip-chip diode and adhered with said film material having Si quantum dots, wherein said chemical vapor deposition is an atmospheric pressure chemical vapor deposition, wherein said ultra blue-violet light interacting with a green, yellow, and red light generated by the Si dots with diffraction and refraction through the transparent substrate to generate a white light.
