Patent JP-3881840-B2 (JP)
IPC: H01L29/49
Filed: 2000-11-14
Granted: 2007-02-14
Abstract: An MIS transistor that uses a silicon carbide substrate has a buried channel structure. The surface orientation of the silicon carbide substrate is optimized so that the device does not assume a normally on state, has good hot-carrier endurance and punch-through endurance, and high channel mobility. In particular, a P-type silicon carbide semiconductor substrate is used to form a buried channel region. To achieve high mobility, the depth at which the buried channel region is formed is optimized, and the ratio between buried channel region junction depth (Lbc) source and drain region junction depth (Xj) is made to be within 0.2 to 1.0. The device can be formed on any surface of a hexagonal or rhombohedral or a (110) surface of a cubic system silicon carbide crystal, and provides a particularly good effect when formed on the (11-20) surface. <IMAGE>

Abstract: The present invention is directed to a silicon carbide field effect transistor. The FET is formed on a silicon carbide monocrystalline substrate. An insulative material gate having a pair of spaced apart sidewalls is patterned on the substrate. The insulative material comprises a first insulation material overlayed by an electrically conductive layer. Within the substrate is lightly doped base regions located partially under the sidewalls of the gate and extending into the exposed substrate. Associated with the lightly doped base regions are heavily doped source regions aligned with the exposed substrate. On the underside of the substrate is a drain region to form the FET. Further in accordance with the present invention, a method to fabricate a field effect transistor is disclosed. The transistor is formed in a monocrystalline substrate of silicon carbide. Forming a transistor on the silicon carbide substrate entails depositing a first electrically insulative layer over the substrate. Next, an electrically conductive layer is deposited over the first insulative layer and then a second electrically insulative layer is deposited over the conductive layer. The following step includes partially removing the second insulative layer and exposing a portion of the first conductive layer to obtain two spaced apart regions of the silicon carbide substrate for forming lightly doped base regions. Then the substrate aligned with the exposed portion of the first conductive layer is lightly implanted with a dopant to form lightly doped base regions. Next, a layer of a third insulative material is formed on the sidewalls of the second insulative material. The following step entails removing the exposed conductive layer not aligned with the second insulative material and third insulative material. Thereby, exposing portions of the first insulating layer and defining a second set of spaced regions of the substrate. The second set of spaced regions are then heavily implanted to form heavily doped source regions. The second insulative material and third insulative material are then removed to form a gate.

Abstract: In the voice control of a device appertaining to consumer electronics, speech inputs of a user are converted into digitized voice signals. First features, which are characteristic of the individual sounds of the speech, and thus permit recognition of the spoken sounds, are extracted from the digitized voice signals. Furthermore, second features, which permit a characterization of the voice of the respective user and are used for distinguishing between the speech inputs of different users, are extracted from the digitized voice signals. This enables the device being operated to distinguish between speech inputs of the present user, which represent operator-control commands, and utterances by other persons, and to respond only to operator-control commands of the present user. Furthermore, the quality of an analysis of the viewing habits of different users can be improved by a distinction between the users.

Abstract: An apparatus for measuring the concentration of a substance in a specimen. The apparatus includes a housing that defines a chamber for the specimen. A radiation source mounted to the housing emits radiation at a wavelength at which the radiation is absorbed by the substance. Two spaced apart receivers are mounted to the housing. Both receivers detect radiation at the wavelength at which it is absorbed by the specimen. Two concave mirrors are disposed in the housing. The mirrors are positioned to split the radiation emitted by the source into two beams, each of the beams being directed to a separate one of the receivers and so that the paths of travel of the beams from the source to the separate receivers are of different lengths. The concentration of the substance is determined by based on the difference in radiation detected by the receivers.

Abstract: A method and apparatus for reducing delay in the transmission of a plurality of packets by performing IP scheduling and header compression at various layers in a multilayer architecture having a plurality of classifications includes scheduling packets according to classifications. If congestion occurs during scheduling, packets may be discarded. Some packet headers may be compressed thereafter. Packets may further be queued in a first and a second queue, after scheduling, discarding, and compressing, according to at least two classifications. Best Efforts packets may be queued into the lower priority second queue. Classifications may be associated with, for example, QoS levels, delay factors, LFI, and Multilink PPP. Scheduling is performed at higher or lower layers in a multi-layer protocol. The lower layer includes a PPP layer. The lower layer may also include an HDLC layer which creates a tag for packets prior to compression being performed thereupon. The tag may be added to packets at some point thereafter. Tags are removed prior to transmission. An outbound packet queue having a queue depth of no greater than one ensures no more than one Best Efforts packet wait time.

Abstract: Flash artifacts in ultrasound flow images are suppressed to achieve enhanced flow discrimination. Flash artifacts typically occur as regions of elevated signal strength (brightness or equivalent color) within an image. A flash suppression algorithm includes the steps of estimating the flash within an image and then suppressing the estimated flash. The mechanism for flash suppression is spatial filtering. An extension of this basic method uses information from adjacent frames to estimate the flash and/or to smooth the resulting image sequence. Temporal information from adjacent frames is used as an adjunct to improve performance.

Abstract: In accordance with the present invention, a family of membrane fusion protein and polynucleotides encoding the proteins have been identified. The proteins and nucleotides are derived from the family Reoviridae. Two membrane fusion proteins have been isolated from reoviruses isolated from poikilothermic hosts: the p14 protein from reptilian reovirus (RRV) isolated from python, and the p16 protein from aquareovirus (AQV) isolated from salmon. The genes encoding these proteins have been cloned and sequenced. Analysis of the amino acid sequences of these proteins show that both lack the typical fusion peptide motif found in other membrane fusion proteins. Expression of these proteins in cells results in cell-cell fusion.

Abstract: The present invention, generally speaking, provides for control of a modulator, such as a polar modulator or conventional linear modulator, to produce high quality RF signals that ramp quickly from a condition of minimal output power to a condition of information-bearing modulation at a specified output power and back down to the condition of minimal output power. Using a polar modulator, for example, it is theoretically possible to perform ramping without degrading the transient measurements beyond the degradation caused by the information-bearing modulation itself. This ideal can be closely approached in practice. Such ramping can be achieved without the need for extensive unit-by-unit calibration on the manufacturing line. <IMAGE>
