  • Patent number: 8232202
    Abstract: An image sensor package and a method for fabricating thereof are provided. A substrate having an insulator filled cavity is provided with an image sensor device electrical connected to a metal layer, thereon. A covering plate is then disposed on the substrate. The substrate is subsequently thinned to expose the insulator. Removing a portion of the insulator, a hole is formed and a conductive layer is filled therein to form a via hole. Next, a solder ball is located over a backside of the substrate which is electrically connected to the metal layer through the via hole. The image sensor package is thinned, thus, the dimensions thereof are reduced.

  • Publication number: 20120091496
    Abstract: A submount and a manufacturing method thereof are provided. The submount, on which at least a semiconductor die is disposed, is mounted on a circuit board. The submount includes a substrate made of a conductive material or a semiconducting material, a plurality of conductive film patterns, and an insulating film pattern. A surface of the substrate includes a die-bonding area and a plurality of conductive areas. The conductive film patterns are individually distributed in the respective conductive areas. The insulating film pattern is disposed between the conductive film pattern and the insulating film pattern, but is not disposed in the die-bonding area. Furthermore, the semiconductor die is disposed in the die-bonding area and is electrically connected with the conductive film patterns. Because the insulating film pattern is not being disposed in the die-bonding area of the submount, the submount structure has improved heat transfer efficiency.
