The goal of this research project is to determine the viability of an interconnect and probing technology which could be used to test and burn-in unpackaged semiconductors at system level speed, and at operating frequency, with voltage and with temperature margins verified. The focus of the research will be to address directly the most costly limitation to widespread MCM use; the problem of readil ...

We propose to demonstrate the feasibility of fabricating a phototransistor using the A1xGa1-xN material system. The proposed phototransitor is based on a GaN-A1xGa1-xN heterojunction which exhibits a 2-D electron gas conduction when a bias is applied on the source-drain terminals. The device is maintained in a nominally OFF state by applying a reverse bias voltage on the gate terminal. With optica ...

Existing balloting codes do not consider all of the forces and interactions that contribute to balloting of hypervelocity projectiles. This effort will result in the definition of a complete mathematical model and the design of an appropriate, user friendly, computational model to predict hypervelocity projectile balloting. Arrow Tech, whose engineers are well known for the development and applica ...

As mission critical avionics systems increase in complexity, the evaluation of their performance and reliability will become more difficult. We propose to select and to integrate a group of reliability and performance analysis tools, specifically designed to handle the fault-tolerant operational aspects of the next generation avionics architectures. These tools will support both hardware and softw ...

The developement of four different doping sources for use within an MBE system is proposed. Two high purity, high uniformity sources for use with Carbon, and two such sources will be developed for use with Tellurium. The purity of the species produced by each cell will be studied with a Residual Gas Analyzer. Recommendations concerning the use of these cells in a solid source MBE system will be su ...

High temperature storage heaters are needed to provide clean, hot air for aerodynamic and propulsion testing of hypersonic vehicles. Vitiation heaters do not properly simulate the vehicle flight conditions, thus limiting the ability to develop tomorrow's aircraft in a timely manner. Yttria-zirconia storage heater development work was sponsored by the Air Force in the 1960's, but did not produce an ...

The cleaning chemicals presently used in the production of ultra large scale integrated (ULSI) circuits pose two major problems. The chemicals contain impurity levels that decrease the manufacutring yield of the circuits. In addition, they require extensive treatment for safe disposal. The process described in this proposal addresses regenerated to produce high purity chemicals. The process is app ...
