  • Patent number: 9741680
    Abstract: A stackable integrated circuit chip layer and module device that avoids the use of electrically conductive elements on the external surfaces of a layer containing an integrated circuit die by taking advantage of conventional wire bonding equipment to provide an electrically conductive path defined by a wire bond segment that is encapsulated in a potting material so as to define an electrically conductive wire bond “through-via” accessible from at least the lower or second surface of the layer.

  • Patent number: 9728507
    Abstract: A cap chip or high density reroute layer for use in a stacked microelectronic module. A first set of electrically conductive reroute layers are defined on a sacrificial substrate. One or more stud bump columns are defined on an exposed conducive pad on a conductive reroute layer. One or more active or passive electronic elements, or both may be electrically coupled to one or more exposed conductive pads. The layer is encapsulated in an encapsulant and the stud bump columns exposed by removing a portion of the encapsulant. A second set of electrically conductive reroute layers is defined on the layer and electrically coupled to the stud bumps. The sacrificial substrate is removed to provide a cap chip or reroute layer.

  • Patent number: 8835218
    Abstract: Layers suitable for stacking in three dimensional, multi-layer modules are formed by interconnecting a ball grid array electronic package to an interposer layer which routes electronic signals to an access plane. The layers are under-filled and may be bonded together to form a stack of layers. The leads on the access plane are interconnected among layers to form a high-density electronic package.

  • Patent number: 8609473
    Abstract: A method for fabricating a stackable integrated circuit layer and a device made from the method are disclosed. A stud bump is defined on the contact pad of an integrated circuit die and the stud-bumped die encapsulated in a potting material to define a potted assembly. A predetermined portion of the potting material is removed whereby a portion of the stud bump is exposed. One or more electrically conductive traces are defined on the layer surface and in electrical connection with the stud bump to reroute the integrated circuit contacts to predetermined locations on the layer to provide a stackable neolayer.

  • Patent number: 8586407
    Abstract: A method for providing a known good integrated circuit die having enhanced planarity from a prepackaged integrated circuit die having a surface warpage such as in a ball grid array (BGA) package is provided. A partially-depackaged integrated circuit package is affixed to a substrate with a spacer element there between such that the active surface of the die within the partially depackaged integrated circuit die is “bowed” slightly upwardly to define a convex surface. The exposed encapsulant on the now-convex surface of the mounted, partially-depackaged integrated circuit package is then lapped or ground away to a predetermined depth so that an integrated circuit die is provided having an enhanced planarity and surface uniformity.

  • Publication number: 20130141137
    Abstract: A physically uncloneable function (PUF) sense and response module fabricated from a stack of integrated circuit chip layers. At least one of the PUF chips in the stack has a unique identifier resulting from random effects of fabrication processes. The PUF chip generates the fingerprint at power-on resulting that in turn is used to generate a private key. The private key generates a public key used to communicate with the outside world. The encrypted data from the outside world is decrypted with the private key. The public key is stored for comparison with pubic keys generated at subsequent power-up operations. If the key changes, tampering is indicated and a predetermined tamper response event is generated such as the erasing of the contents of a memory.

  • Patent number: 8415819
    Abstract: An energy-harvesting buoy is provided comprising an air-pressure generator, such as a piezo-electric generator, or any other generator that can harvest energy from an air pressure. The energy harvesting buoy consists of a first float and a second float. An air pressure is created when relative vertical motion occurs between the first float and the second float which drives an air pressurization means such as a piston driven air pump using a linkage member pivotably mounted between the respective floats. The generator uses the air pressure from the air pressurization means to drive the generator to generate electrical power.

  • Patent number: 8271262
    Abstract: The invention comprises a lip reading device having a capacitive array for enhanced portable speech recognition. The capacitive array of the invention produces a sequence of signal frames or signal data sets (i.e., digitized output) representative of the proximity and motion of a user's lips at a predetermined sample rate and resolution. The sequence of signal data sets is stored in a first electronic memory and are compared against a reference data set representative of a predetermined acoustic signal stored in a second electronic memory. The attributes of signal data set are compared against the reference data set for likely data matches based on predetermined criteria.

  • Publication number: 20120211886
    Abstract: A method for fabricating an integrated circuit chip-scale package and a device made from the method. One or more IC chips are mounted on a carrier and a stud bump defined on an IC pad. The stud-bumped IC is encapsulated to define a potted assembly layer which is thinned to expose the stud bump. Conductive first traces are defined and coupled to the stud bump to reroute the IC pads. A dielectric layer is provided and vias defined there through to expose the first traces. Electrically conductive second traces are disposed on the dielectric layer surface that are coupled to the first traces to reroute the IC pads to define a chip scale package.

  • Publication number: 20120185636
    Abstract: A high capacity, secure and tamper-resistant computer data memory device. The device uses a plurality of dedicated memory controller elements in communication with an anti-tamper module that generates a tamper response when a predetermined tamper event occurs. The tamper response may be provided as the erasure or zeroization of the contents of a memory in the devices such as erasing one or more encryption keys. The elements of the device are preferably provided in a stacked configuration with rerouted I/O pads to obfuscate the I/O and function of the devices in the stack. In one embodiment, a data transfer governance means is provided. In a further embodiment, a current negotiation means is disclosed to permit the device to request a predetermined current from a host device. In a yet further embodiment, a portable safe house computing device is provided.

  • Publication number: 20120069528
    Abstract: A process and product made from the process is disclosed to minimize solder collapse during solder reflow. Predetermined bond pads on a layer or component have a solder paste such as Sn63 solder paste with a first lower reflow temperature applied and a spacer element such as an SAC solder ball or stud bump having a predetermined geometry with a second higher reflow temperature applied. The SAC solder balls or stud bumps act as spacing elements but do not interact with the solder paste such that the solder paste may be reflowed while precisely maintaining the space between the layers.

  • Patent number: RE43877
    Abstract: A preprocessed semiconductor substrate such as a wafer is provided with a metal etch mask which defines singulation channels on the substrate surface. An isotropic etch process is used to define a singulation channel with a first depth extending into the semiconductor substrate material. A second anisotropic etch process is used to increase the depth of the singulation channel while providing substantially vertical singulation channel sidewalls. The singulation channel can be extended through the depth of the substrate or, in an alternative embodiment, a predetermined portion of the inactive surface of the substrate removed to expose the singulation channels. In this manner, semiconductor die can be precisely singulated from a wafer while maintaining vertical die sidewalls.
