  • Patent number: 6242794
    Abstract: A semiconductor device and method of fabricating the device. An emitter region is formed self centered and self aligned symmetrically with a base region. Using frontside processing techniques, a collector is formed symmetrically self-aligned with the base region and the emitter region. The collector region may be further formed self-centered with the base region using backside processing techniques. The self-aligned and self-centered symmetric structure virtually eliminates parasitic elements in the device significantly improving the device performance. The device is scalable on the order of approximately 0.1 microns. The method also provides reproduceability and repeatability of device characteristics necessary for commercial manufacture of the symmetric device.

  • Patent number: 5939742
    Abstract: A field-effect photo-transistor, being a three-terminal photosensing electrical device, based on integrated metal oxide semiconductor (MOS) technology. The device features a high output impedance which makes it particularly suitable as a photosensor for active pixel imaging arrays. Unlike the bipolar photo-transistor, which is a device well known in the art, the field-effect phototransistor is more compatible with MOS VLSI (Very Large Scale Integration) technology by inherently being a unipolar type device. Active pixel imaging arrays based on the disclosed invention can be integrated on the same semiconductor substrate with conventional digital or mixed signal processing functions to produce single-chip image processors for video or still picture cameras.

  • Patent number: 5365092
    Abstract: A CCD which is designed and processed so that most of each pixel is covered only with an ultra-thin gate electrode so that the CCD can be frontside illuminated and still achieve good sensitivity in the ultra-violet and soft x-ray spectral range. More specifically, in the present invention, the usual three gate structure and corresponding polysilicon layers 1, 2 and 3 of conventional thickness are reduced in width and supplemented by a fourth ultra-thin layer of polysilicon dubbed herein, poly 4, that is deposited over the entire array. This fourth layer, poly 4, makes contact with poly 3, so that when poly 3 is driven, it also drives poly 4, thus allowing charge to collect and transfer as in a normal three phase CCD. However, because the deposition thickness of the poly 4 layer is on the order of 400 Angsttoms, as opposed to conventional thicknesses of 2000 to 5000 Angsttoms, poly 4 is essentially transparent to photons and thereby allows achievement of high quantum efficiency.

  • Patent number: 5365098
    Abstract: A floating gate is formed via a first gate insulating film over the channel region between source and drain regions which are formed in a semiconductor substrate. A control gate is formed via a second gate insulating film over the floating gate. A low impurity concentration semiconductor region is formed on the side of the control gate which faces the floating gate. When erasing, a depletion layer is produced in this low impurity concentration region and further saturates the erase characteristic for the erasure time by decreasing the capacitance between the control gate and the floating gate.

  • Patent number: 5359211
    Abstract: A high voltage protection circuit includes a breakdown network for providing a discharge path between a pair of terminal of a circuit to be protected. Each network conducts current between a supply terminal and another terminal at a low threshold voltage value when power is removed from the supply terminal. The network increases the threshold value when power is applied to the supply terminal to prevent conduction through the breakdown network during normal operation of the circuit to be protected. In one implementation, the protection circuit includes anti-latching circuitry connected to the breakdown network for preventing the breakdown network from latching on after or during the time power is applied to the supply terminals. To minimize the degradation of DC operating characteristics, the leakage currents, due to the protection circuit, between the first terminal and the positive supply terminal, and between the first terminal and the negative supply terminal cancel each other.

  • Patent number: 5357136
    Abstract: A semiconductor device having a bonding pad region, and a method of its fabrication. A conductive layer is formed on an isolation layer separating transistors of the device, to anchor the interconnection layer on the bonding region. The conductive layer may be formed from the same layer of material that gate electrodes of the transistors are formed. An oxide insulation layer covers the conductive layer and has at least one opening exposing the conductive layer in the bonding pad region. A barrier metal layer, formed on the diffusion regions and the insulation layer, extends into the opening where it makes a firm direct connection with the exposed conductive layer. A bonding pad is formed on the barrier metal layer by providing the interconnection layer on the barrier metal layer. Since the conductive layer and the barrier metal layer are firmly connected, and secures the interconnection layer in the bonding pad structure.
