A novel technological approach was recently devised by Sumi Tech engineers to fabricate multilayer electronic components, which enables the manufacture of devices with very high volumetric efficiency and reliability. Inexpensive electrode materials such as copper, or aluminum are potential candidates, since the process takes place at relatively low ambient temperature (e.g., less than 400 C), thus ...

BTA Technology, Inc. will transform a prototype circuit reliability simulator into a commercial computer-aided design tool for widespread industrial use. BERT (Berkeley Reliability Tool) is a revolutionary simulator that predicts integrated circuit reliabilty due to the effects of hot carrier induced degradation in MOS and bipolar transistors. Oxide breakdown and interconnect and contact electromi ...

GROWTH OF OEDERED Ga(1-x)In(x)P ON GaAs, AS A THIN FILM MATERIAL SHOWING VERY STRONG NONLINEAR OPTICAL (nlo) EFFECTS, WILL BE ACCOMPLISHED BY METALORGANIC CHEMICAL VAPOR DEPOSITION (MOCVD). IT IS WELL KNOWN THAT MOCVD-GROWN Ga(1-x)In(x)P DISPLAYS VERY STRONG ORDERING OF THE Ga- AND In-SUBLATTICES, AND THAT DEGREE OF ORDERING IS CONTROLLED BY GROWTH PARAMETERS. STRONG ORDERING SHOULD LEAD TO THE LA ...

OSCILLATORS ARE FUNDAMENTAL BUILDING BLOCKS OF MONOLITHIC SUBMILLIMETER RECEIVER SYSTEMS FOR AIRBORNE AND SATELLITE APPLICATIONS. WE PROPOSE TO RAPIDLY DEVELOP SUBMILLIMETER SUPERCONDUCTING JOSEPHSON OSCILLATORS OF 100-100000 JUNCTIONS WITH UP TO 1 MW OUTPUT POWER FOR 100 GHz-3 THz FREQUENCY RANGE. PROPOSED OSCILLATORS WOULD OFFER UNPRECEDENTED PERFORMANCE IN TERMS OF POWER, EFFICIENCY, TUNABILITY ...

One highly desired improvement for neutron sensing is an imaging neutron detector with high two-dimensional spatial resolution and a large detector area. At present, achievable real-time neutron imaging detector resolution is only about 1 mm. The innovation proposed is to adapt for neutron imaging the high spatial resolution Microchannel Plate (MCP) detector technology so widely used for detecting ...

The III-V nitride semiconductor family affords many unique properties which make these materials attractive candidates for producing electronic and optoelectronic devices. Much progress has been made in epitaxial thin film growth of nitrides using metalorganic chemical vapor deposition (MOCVD) and molecular beam epitaxy (MBE) during the last decade. These efforts are hindered by the lack of lattic ...

Stratedge Corp fabricates high performance ceramic multichip modules through the use of a set of specially formulated laminating materials. This effort will develop laminating materials and processes that will be compatible with existing superconducting materials. The specific superconducting materials to be integrated in a multilayer structure are yttrium-barrium-copper oxide on a lanthanum alumi ...

New computer systems based on a "switched" architecture are emerging commercially and promise to revolutionize multi-processor systems used in real-time applications. JAYCOR and its subcontractor Concurrent Computer Corporation propose to develop a robust high performance-switched architecture computer which will provide the processing power required by current and future BMDO systems. The propose ...

Pulse tubes are the cutting edge of regenerative cryocooler development. Their simplicity and ruggedness recommend pulse tubes over older technologies in a variety of military and civilian applications. In addition, since they have no moving parts in the cold head, pulse tube cryocoolers cause little or no vibration. That attribute is particularly important in computer chip manufacture, particular ...
