摘要： An image sensor package having at least one chip supporting bar secured to a top surface of an image sensor chip. The thickness of the chip supporting bar is absorbed within a vertical dimension of wire loops that connect bonding pads to leads so that the chip supporting bar does not contribute to the thickness of the image sensor package. An exposed back surface of the image sensor chip enhances thermal dissipation.
