  • Publication number: 20220068877
    Abstract: A semiconductor device assembly includes a substrate having a plurality of external connections, a first stack of semiconductor dies disposed directly over a first location on the substrate and electrically coupled to a first subset of the plurality of external connections, and a second stack of semiconductor dies disposed directly over a second location on the substrate and electrically coupled to a second subset of the plurality of external connections. A portion of the semiconductor dies of the second stack overlaps a portion of the semiconductor dies of the first stack. The semiconductor device assembly further includes an encapsulant at least partially encapsulating the substrate, the first stack and the second stack.

  • Publication number: 20210358888
    Abstract: An apparatus includes an integrated circuit and a substrate coupled to the integrated circuit. The substrate includes a primary layer having a first surface that is a first external surface of the substrate. The primary layer includes an open area that extends through the primary layer to an inner layer of the substrate. The substrate includes a secondary layer. The inner layer is located between the primary layer and the secondary layer. The inner layer includes a third surface that is orientated approximately parallel to the first surface of the primary layer. A portion of the third surface of the inner layer is exposed via the open area of the primary layer. A first plurality of wire bond pads are disposed on the portion of the third surface of the inner layer that is exposed via the open area of primary layer.

  • Patent number: 8354749
    Abstract: Improved techniques to produce integrated circuit products are disclosed. The improved techniques permit smaller and less costly production of integrated circuit products. One aspect of the invention is that the integrated circuit products are produced a batch at a time, and that singulation of the batch into individualized integrated circuit products uses a non-linear (e.g., non-rectangular or curvilinear) sawing or cutting action so that the resulting individualized integrated circuit packages no longer need to be completely rectangular. Another aspect of the invention is that the integrated circuit products can be produced with semiconductor assembly processing such that the need to provide an external package or container becomes optional.

  • Patent number: 7822883
    Abstract: Enclosed re-programmable non-volatile memory cards include at least two sets of electrical contacts to which the internal memory is connected. The two sets of contacts have different patterns, preferably in accordance with two different contact standards such as a memory card standard and that of the Universal Serial Bus (USB). One memory card standard that can be followed is that of the Secure Digital (SD) card. The cards can thus be used with different hosts that are compatible with one set of contacts but not the other. A cover that is hinged to the card to normally cover one set of contacts can be manually rotated out of the way when that set of contacts is being used.

  • Patent number: 7416132
    Abstract: The present invention, roughly described, pertains to a small memory card that includes features which allow the memory card to be more easily handled by a user. In various embodiments, the memory card can include a chamfer and/or a raised portion that allows the memory card to be more easily grabbed by a human hand (or mechanical device) and also provides additional room to store passive devices such as capacitors and/or resistors. Because different electronic devices use different types of memory cards, an adaptor is provided that allows the memory cards disclosed herein to be used in ports or connectors on electronic devices that are meant for other types of memory cards.

  • Patent number: 7303127
    Abstract: Surface optical characteristics, alpha-numeric markings and other design features of memory cards, flash drives and similar devices combine to provide the devices with unique outer appearances. In one example, markings are held a distance from a reflective surface such that reflections of the markings off the surface are visible adjacent the markings. In another example, a diffusely reflecting rainbow hologram is combined with such markings or other design features.
