  • Patent number: 8664750
    Abstract: A semiconductor substrate including a carrier, a first conductive layer and a second conductive layer is disclosed. The carrier has a first surface, a second surface, and a concave portion used for receiving a semiconductor element. The first conductive layer is embedded in the first surface and forms a plurality of electric-isolated package traces. The second conductive layer is embedded in the second surface and electrically connected to the first conductive layer. The semiconductor substrate can be applied to a semiconductor package for carrying a semiconductor chip, and combined with a filling structure for fixing the chip. Furthermore, a plurality of the semiconductor substrates can be stacked and connected via adhesive layers, so as to form a semiconductor device with a complicated structure.

  • Patent number: 8547287
    Abstract: Provided is a circuit for an electronic device having a non-planar transparent resonator. The transparent resonator is mounted on said circuit so as to at least partially occupy a footprint of another component of the circuit. The transparent resonator forms part of a light pathway on said circuit for transmitting light to or from said another component. Also provided is a transparent dielectric resonator antenna (DRA) for optical applications. Since the DRA is transparent, it can let light pass through itself and, thus, the light can be utilized by an optical part of a system or device. The transparent DRA can be placed on top of a solar cell. Since the DRA does not block the light, the light can reach the solar cell panel and power can be generated for the system or device. The system or device so obtained is very compact because no extra footprint is needed within the system or device for the DRA. It finds application in compact wireless applications that need a self-sustaining power device.

  • Publication number: 20130030457
    Abstract: A trocar sleeve for minimally invasive surgery, having a first sleeve part, which has essentially the shape of a straight tubular piece with a longitudinal axis, and having a second sleeve part, which at least partly surrounds the first sleeve part in close contiguity and is movable during use with respect to the first sleeve part. The mobility of the second sleeve part in relation to the first sleeve part consists essentially only in rotatability of the second sleeve part around the first sleeve part, and in addition the first sleeve part and the second sleeve part each comprise on their distal axial ends a flange part that extends radially outward at an angle of less than 180 degrees from the respective sleeve part.

  • Patent number: 8089943
    Abstract: A method for allowing short-ranged communication devices to communicate with each other using the Internet. Cell servers are provided in first and second zones linked to the Internet and adapted for transmitting voice and other digital data over the Internet such as using VoIP. The method includes registering users of short-range enabled devices, such as Bluetooth cell phones, with a communication system and storing a device identifier along with a user ID and password. A contact list is stored for each registered user. The method includes a registered user entering a cell serviced by a server, the server discovering the user's device, logging the user into the system based on the device identifier and an entered user ID and password, receiving a communication request to chat with one of the listed contacts, and establishing a communication session using time previously awarded to the user for receiving marketing content.

  • Publication number: 20110287560
    Abstract: A method for fabricating a flip-chip semiconductor package. The method comprises processing a semiconductor device, for example a semiconductor chip and processing a device carrier, for example a substrate. The semiconductor device comprises bump structures formed on a surface thereof. The substrate comprises bond pads formed on a surface thereof. Processing of the semiconductor chip results in heating of the semiconductor chip to a chip process temperature. The chip process temperature melts solder portions on the bump structures Processing of the substrate results in heating of the substrate to a substrate process temperature. The method comprises spatially aligning the semiconductor chip in relation to the substrate to correspondingly align the bump structures in relation to the bump pads. The semiconductor chip is then displaced towards the substrate for abutting the bump structures of the semiconductor chip with the bond pads of the substrate to thereby form bonds therebetween.
