  • Publication number: 20080116589
    Abstract: An integrated voltage regulator may be provided on the bottom of a ball grid array processor package. This may be done despite the fact that conventionally integrated voltage regulator chips are too thick to fit in the area normally available between the motherboard and the ball grid array package because that area is defined by solder balls of a necessarily limited height which is conventionally believed to be too small to accommodate the integrated voltage regulator.

  • Patent number: 6646808
    Abstract: By forming a microlens of negative photoresist, economical microlens fabrication processes may be used which, in some embodiments, may achieve microlenses having good optical clarity and high thermal stability. In one embodiment, a positive photoresist may be used as a pattern mask to transfer a pattern to the negative photoresist. The microlenses may be formed by dry etching the positive photoresist which acts as a mask to transfer a pattern to the underlying negative photoresist. At the same time a scratch protection layer may be formed over regions not overlying optical sensors.
