  • Patent number: 7064355
    Abstract: Light emitting devices with improved light extraction efficiency are provided. The light emitting devices have a stack of layers including semiconductor layers comprising an active region. The stack is bonded to a transparent optical element having a refractive index for light emitted by the active region preferably greater than about 1.5, more preferably greater than about 1.8. A method of bonding a transparent optical element (e.g., a lens or an optical concentrator) to a light emitting device comprising an active region includes elevating a temperature of the optical element and the stack and applying a pressure to press the optical element and the light emitting device together. A block of optical element material may be bonded to the light emitting device and then shaped into an optical element. Bonding a high refractive index optical element to a light emitting device improves the light extraction efficiency of the light emitting device by reducing loss due to total internal reflection.

  • Patent number: 6987306
    Abstract: This invention describes an approach for monolithically integrating all the components of a photoreceiver—optical amplifier, optical band-pass filter, and photodiode module—on a single chip. The photoreceiver array employs unique optical amplifier and conversion technologies that provides the ultra-sensitivity required for free space optical communications networks. As an example, by monolithically integrating a vertical cavity surface emitting laser-diode (VCSEL) optical preamplifier with a photodiode receiver and related amplifiers and filters on the same chip, sensitivities as low as ?47 dBm (62 photons/bit at 2.5 Gb/s), along with an order of magnitude reduction in size, weight, and power consumption over comparable commercial-off-the-shelf (COTS) components can be demonstrated.

  • Patent number: 6984869
    Abstract: The present invention provides a diffusion resistor that is formed in the substrate. A diffusion region is formed within the substrate that contains first and second contact regions extending downward from the surface of the substrate. Third and fourth contacts are also located within the diffusion region between the first and second contacts and define a conduction channel therebetween. This contact also extends downward from the surface of the substrate. These contacts are connected to metal layers. The first and second contacts form the two ends of the diffusion resistor; the third and fourth contacts connect to N+p? diodes such that application of a voltage to these contacts forms respective depletion regions within the diffusion region. The depletion regions change in size depending on the voltage applied to their respective contact, thereby changing the resistance of the depletion resistor.

  • Patent number: 6965129
    Abstract: Switching operations, such as those used in memory devices, are enhanced using a thyristor-based semiconductor device adapted to switch between a blocking state and a conducting state. According to an example embodiment of the present invention, a thyristor-based semiconductor device includes a thyristor having first and second base regions coupled between first and second emitter regions, respectively. A first control port capacitively couples a first signal to the first base region, and a second control port capacitively couples a second signal to the second base region. Each of the first and second signals have a charge that is opposite in polarity, and the opposite polarity signals effect the switching of the thyristor at a lower power, relative to the power that would be required to switch the thyristor having only one control port.

  • Patent number: 6946716
    Abstract: A process is described for the fabrication of submicron interconnect structures for integrated circuit chips. Void-free and seamless conductors are obtained by electroplating Cu from baths that contain additives and are conventionally used to deposit level, bright, ductile, and low-stress Cu metal. The capability of this method to superfill features without leaving voids or seams is unique and superior to that of other deposition approaches. The electromigration resistance of structures making use of CU electroplated in this manner is superior to the electromigration resistance of AlCu structures or structures fabricated using Cu deposited by methods other than electroplating.
