  • Publication number: 20110243541
    Abstract: A defocus calibration module is applied in a light-sensing system utilized for sensing a measured object for generating a sensed image. The light-sensing system comprises a light-emitting component, a focusing component, and an image sensor. The light-emitting component emits a detecting light to the measured object so that the measured object generates a reflecting light. The focusing component focuses the reflecting light to the image sensor. The image sensor generates the sensed image according to the reflecting light. The defocus calibration module has a calibrating object for blocking a part of the detecting light and the reflecting light for forming images at a first and a second calibration imaging locations in the sensed image. In this way, the defocus calibration module calculates a defocus parameter representing the defocus level of the light-sensing system according to the first and the second calibration imaging locations, and accordingly calibrates the sensed image.

  • Publication number: 20100327442
    Abstract: The present invention relates to a package and the method for making the same, and a stacked package. The method for making the package includes the following steps: (a) providing a carrier having a plurality of platforms; (b) providing a plurality of dice, and disposing the dice on the platforms; (c) performing a reflow process so that the dice are self-aligned on the platforms; (d) forming a molding compound in the gaps between the dice, and (e) performing a cutting process so as to form a plurality of packages. Since the dice are self-aligned on the platforms during the reflow process, a die attach machine with low accuracy can achieve highly accurate placement.
