  • Patent number: 7441925
    Abstract: A method for assembling light emitting diode units and a substrate in a light source module and a structure thereof are provided. The light emitting diode unit is made of a light emitting diode and a carrier. Every light emitting diode has a flanged profile in the bottom to form a leaned plane, and a corresponding hole is formed on the substrate. Hence, when the light emitting diodes are pressed on the surface of a radiator by the substrate to make a closer contact, the light emitting diodes will be able to bear the pressure by the flanged design.

  • Publication number: 20080080814
    Abstract: A silicon bulk-micromachining technology is used to fabricate a GMR filter by exploiting the structure of a suspended silicon nitride (SiNx) membrane on the silicon substrate. A first silicon nitride (SiNx) thin film and a second silicon nitride (SiNx) thin film are formed on opposite sides of the silicon substrate. A first opening is defined in the first silicon nitride (SiNx) thin film, and a grating structure is defined in the second silicon nitride (SiNx) thin film. By etching off a portion of the silicon substrate exposed from the first opening until a portion of the second silicon nitride (SiNx) thin film is exposed from the first opening, a light path space is defined.
