Inventor: LUDOWISE MICHAEL
IPC: H01L21/8252
Filed: 1995-01-20
Abstract: A fabrication method for providing a semiconductor light-emitting device (36 ; 72) includes growing a plurality of layers on a semiconductor substrate, including forming a lower cladding layer (12; 40) and an active region (14; 42) for generating lightwaves. A laminated cladding structure is formed on the active region. The laminated cladding structure (16 ; 44) includes a lower layer (18 ; 46, 48 ; 76) that is substantially aluminum-free to inhibit oxidation and includes an upper layer (20 ; 50 ; 74) that is aluminum-bearing in order to promote oxidation. The upper layer of the lamination is oxidized along selected first regions (26, 28) and is selectively masked to prevent oxidation for second regions (30, 52). The oxidation of the first region is carried out under conditions such that a native oxide is formed throughout the thickness of the first regions. Electrical current to the active region for operating the light-emitting device is channeled via the unoxidized region of the upper layer of the lamination. In a preferred embodiment, the device is an InGaAsP-AIInAs-InP laser. Other electronic devices, such as FETs (58), can be also formed using the top-down approach. Preferably, oxidation is limited to an upper III-V semiconductor layer by forming a lower III-V semiconductor layer that includes In and/or P. Lateral oxidation can also be realized using this approach.

Abstract: When an element of an internal circuit is arranged in the vicinity of an input/output terminal of an LSI chip, electrostatic break down is caused in an internal circuit element by discharge current generated between an input/output terminal and a grounding terminal or a power source terminal. Therefore, the elements are arranged with a distance to cause dead space therebetween to make down-sizing of the LSI chip difficult. Therefore, a resistor is disposed between an input/output terminal and a protection element connected thereto. The resistor causes increasing of resistance of a current path from the input/output terminal to the grounding terminal, at the common wiring. Thus influence of the electrostatic break down for the element of the internal circuit can be restricted to permit location of the resistor to permit the internal circuit element to be arranged in the vicinity of the protection element of the input/output terminal. Thus, a problem of the dead space can be solved and down-sizing of the LSI is enabled.

Abstract: A DMOS power transistor has: a source/drain terminal on a bottom surface of a wafer of a first conductivity type; a body region of a second conductivity type, in a top surface of the wafer; drain/source regions of the first conductivity type bounded laterally and from below by the body region; source/drain regions of the first conductivity type bounded laterally by the body region but in electrical contact with the source/drain terminal via a first conductivity type portion of the wafer; and a gate defining openings overlying the drain/source regions and openings overlying the source/drain regions. The gate's size controls channel lengths in the transistor so that channel lengths are insensitive to diffusion caused by thermal processes, and the transistor is easily fabricated on the same chip as other CMOS devices. Contacts for a drain/source terminal, a gate terminal, and a body terminal are formed from a single metal layer overlying the top surface of the wafer. Active regions of the power transistor are laid out in cells. In one embodiment, the drain/source regions are an array of uniformly spaced squares, and the source/drain regions are interspersed between the drain/source regions. The source/drain regions' widths are selected to minimize the resistance per area of the transistor and may be larger than the minimum design rule requirements.

Abstract: For use in a bi-directional cable television (CATV) communication
system, there is described a device which eliminates all RF ingress noise
from entering the CATV network in the upstream communication path.
The device includes a shunt filter (155), a detector (156) and a filter (154)
with a bandwidth equal to the bandwidth of the upstream communication
path. The detector (156) monitors signals transmitted in the upstream
bandwidth and detects when a valid upstream communication is being
transmitted. Upon detection of this valid signal, the detector (156)
deactivates the shunt filter (155), thereby removing the shunt filter from the
upstream communication path to allow the valid transmission to be sent.
When the end of the valid transmission is detected and a predetermined
delay has elapsed, the detector (156) activates the shunt filter (155) to
block all upstream transmissions in the upstream communication
bandwidth.

Inventor: GREENBERG ALBERT GORDON
IPC: H04M3/42
Filed: 1997-10-24
Abstract: Because it is difficult to provide adequate quality
of service to large-bandwidth calls in integrated-services
networks, service providers may allow some customers to
book ahead their calls. The present invention provides a
scheme resource sharing among book-ahead calls (that
announce their call initiation and holding times upon
arrival) and non-book-ahead calls (that do not announce
their holding times and enter service immediately, if
admitted). The basis for this sharing is an admission
control algorithm in which admission is allowed if an
approximate interrupt probability (computed in real time)
is below a threshold. Simulation experiments show that
the proposed admission control methodology is superior to
alternative schemes that do not allow interruption, such
as a strict partitioning of resources.

Abstract: A method and apparatus are disclosed for determining the boundaries of guard
intervals of data symbols being received in a coded orthogonal frequency division
multiplexed signal. Temporal samples separated by an interval of an active interval
of a data symbol are associated in pairs, and difference signals obtained. The
dispersion of a first comparison block of difference signals is determined, and
compared to the dispersion of a second comparison block of difference signals, the
second comparison block being displaced from the first comparison block by n
samples. An F ratio is calculated for the dispersions of the two blocks. F ratios are
iterated in a succession of comparison blocks, and a signal representing the F ratios
subjected to peak detection. The peaks represent the boundaries of the symbol's
guard interval. This information is utilized in synchronizing an FFT window for
subsequent signal reconstruction.

Abstract: Cette invention concerne un processus permettant de fabriquer des céramiques supraconductrices, alignées biaxialement et hautement texturées, lesquelles se présentent sous forme de conducteurs composites entourés d'un matériau matriciel dont les couches interfaciales au moins sont également texturées biaxialement. Dans les modes de réalisation préférés, le conducteur se compose de plusieurs filaments tandis que la matrice reste sensiblement malléable. Les étapes clés de ce processus consistent à fabriquer un composite comportant des filaments globalement plats, malléables, fins et faits d'un précurseur d'alliage de la céramique supraconductrice, lesquels filaments sont entourés d'une matrice malléable dont les couches interfaciales au moins peuvent être convenablement texturées; effectuer un traitement thermo-mécanique du composite en une ou plusieurs étapes, et dans des conditions permettant de texturer au moins les couches interfaciales de la matrice tandis que les filaments restent à l'état de précurseur; et enfin, texturer par réaction le matériau du filament de manière à former et texturer la céramique supraconductrice voulue dans le composite, ceci par une croissance quasi épitaxiale favorisée par les couches interfaciales texturées, et sans déformation notoire des grains supraconducteurs. En ce qui concerne les oxydes supraconducteurs, le traitement thermo-mécanique consiste à texturer biaxialement les couches interfaciales par des traitements thermo-mécaniques dont une partie au moins se déroule durant la fabrication; oxyder le composite dans des conditions qui permettent de préserver ou d'accroître la texture des couches interfaciales, qui permettent de former des phases sous-oxydes dans les filaments, mais qui ne permettent pas de transformer de grandes quantités desdites phases sous-oxydes en l'oxyde supraconducteur voulu; et enfin, effectuer avant, pendant ou après l'oxydation, mais avant la réaction, le traitement thermique du composite de manière à achever le développement d'une texture biaxiale dans les couches interfaciales.
