A NOVEL NON-CONTACT NON-INVASIVE INFRARED (IR) SENSOR IS PROPOSED FOR IN-SITU DIAGNOSTICS IN CVD REACTORS. DURING CVD PROCESSES, THE SUBSTRATES WILL BE HEATED. THE IR SENSOR TAKES THE ADVANTAGE OF THE HEATED SUBSTRATE AS THE SOURCES OF IR RADIATION. BY SENSING AND ANALYZING THE IR RADIATION FROM A SUBSTRATE, THE SUBSTRATE SURFACE CAN BE PROBED. MOREOVER, LOW TEMPERATURE SILICON EPITAXY HAS BEEN CH ...

RECENT ADVANCES IN HIGH TEMPERATURE SUPERCONDUCTING (HTSC) THIN FILM TECHNOLOGY ENABLE THE FABRICATION OF LOW-LOSS COMPONENTS THAT WILL IMPROVE THE COST AND PERFORMANCE OF CHANNELIZED RECEIVERS. CHANNELIZED RECEIVERS ARE USED IN SATELLITE TRANSPONDER, ELECTRONIC WARFARE AND ELECTRONICS INTELLIGENCE APPLICATIONS AND ARE COMPRISED OF A GROUP OF NARROW BAND RECEIVERS THAT COVER INDIVIDUAL SLOTS IN A ...

SIGNIFICANT SIMPLIFICATION OF MICROWAVE PHASED ARRAY ANTENNA SYSTEM ARCHITECTURES CAN BE ACHIEVED WITH HTSC DEVICE TECHNOLOGY. ELIMINATION OF THE LOW NOISE AMPLIFIERS (LNAS) CAN BE ACCOMPLISHED THROUGH REPLACEMENT OF THE GAAS PHASE SHIFTERS WITH LOW LOSS HTSC COMPONENTS. A REDUCTION IN COMPLEXITY LOWERS BOTH SYSTEM WEIGHT ANDCOST. KEY TO HTSC TECHNOLOGY INSERTION IN PHASED ARRAY ANTENNAS IS THE DE ...

NUCLEATION REMAINS AN OBSTABLE TO THE GROWTH OF SINGLE CRYSTAL FILMS OF DIAMOND ON NON-DIAMOND SUBSTRATES. TWO KEY FACTORS CONTROL THE NUCLEATION OF DIAMOND ON SI: THE FORMATION OF A SIC LAYER BETWEEN THE SI AND THE FILM, AND SPONTANEOUS NUCLEATION OF THE SIC ON THE CONTAMINATED SI SURFACE. IMPRECISE CONTROL OF THE NUCLEATED SIC LAYER HAS DEFEATED PREVIOUS ATTEMPTS AT HETEROEPITAXY OF DIAMOND ON S ...

FERROELECTRICS (FE) HAVE A LARGE COMMERCIAL POTENTIAL AS PIEZOELECTRIC ELEMENTS, DIELECTRICS FOR CAPACITORS, AND IN OPTICAL GUIDED-WAVE DEVICES. MATERIALS PROCESSING HAS LIMITED APPLICATIONS IN MICROELECTRONICS AND PHOTONICS, HOWEVER, AND FEW METHODS ARE CAPABLE OF DEPOSITING HIGH QUALITY THIN FILMS COMPATIBLE WITH STANDARD SI INTEGRATED CIRCUIT PROCESS TECHNOLOGY. METALORGANIC CHEMICAL VAPOR DEPO ...

A SYSTEM DESIGN IS PROPOSED FOR A LOW COST MAN-PORTABLE SATELLITE DIRECT DOWNLINK TERMINAL TO RECEIVE DIGITAL TRANSMISSIONS FROM TIROS-N, GOES, METEOSAT AND DMSP WEATHER SATELLITES. KEY AREAS OF ENABLING TECHNOLOGY ARE IDENTIFIED AND DISCUSSED. IN PHASE I, ASDC WILL DEVELOP AND BREADBOARD SUFFICIENT HARDWARE AND SOFTWARE TO DEMONSTRATE A WORKING PROOF OF CONCEPT SYSTEM. SPECIFICATIONS AND HARDWARE ...
