A major limitation for semiconductor yield for technologies below O.35.micro.m is the availability of pure, particle-free (particles

In order for Knowledge-Based Systems to continue progressing into the mainstream of computing technology, they must become capable of addressing large and complex problems. Conventional systems are achieving this progress by moving to network infrastructure models, distributed systems, and finer granularity that is object-oriented. Analogous architectures are needed for Knowledge-Based Systems so ...

Silicon carbide materials will revolutionize semiconductor devices for military and commercial markets. The material's wide bandgap, high electric field breakdown, high thermal conductivity give SiC capabilities that far exceed those of silicon or gallium arsenide. Despite significant progress in silicon carbide development, fundamental defects--most prominently micropipes--persist. If SiC is to s ...

The properties of single-crystal silicon carbide are such that electronics devices from this material have demonstrated remarkable performance characteristics. Despite the material's promise, the material has not yet found acceptance in mainstream device markets because of the material's high cost, among other reasons. This Phase I SBIR proposes an SiC source powder with unique properties which wi ...

This Phase I project will model, design, fabricate and test several types of true three-dimensional submillimeter helical antenna arrays. The true 3D helical antennas are an improvement over the planar microstrip antennas because they exhibit wideband impedance characteristics, circular polarization, allow a simple feed network and left and right hand polarizations are easily realized. A new fabri ...

Developing a set of tools that is automated, integrated, and compliant with the deired goals of this SBIR is not a simple task. If a coordinated approach is not taken from the start, then a hodgepodge of tools and capabilities for a hodgepodge of environments wil be developed with unwanted outcome of falling short of the desired goals. Therefore, SYNETICS proposes to establish a CASE-like enviro ...

In order to develop faster, lighter, more maneuverable, and more accurate defense interceptors, jet interaction (JI) aerodynamic controls are being pursued to achieve highly effective control authority across large portions of the battlespace. The reliable use of JI to control a kill vehicle (KV) during divert maneuvers or attitude adjustments involves exploitation of the aerodynamic interactions ...

This proposal addresses the exploratory development and evaluation of novel thin film and/or monolithic detonators as diverters for guided spinning projectile use. A number of such detonators comprise a diverter technology termed RMDM, (for Ring Matrix Diverter Module) which, along with the SSPG (for Small Spinning Projectile Guidance) seeker, forms the basis for inexpensive miniature guided proje ...

Breathable release coatings that can withstand processing conditions up to 750F are needed for use on ceramic tooling. In situ removal of volatiles in solvent-based composite processing is a critical issue that will enable production of high quality parts at lower cost per part. Current release coatings meet neither the temperature nor the solvent transport requirements of solvent-based composit ...

Rocket motors that develop greater thrust with lower weight and volume require-ments are an ever present goal of the BMDO. One method of providing this is through formulation of higher energy propellant mixtures. TPL proposes to develop a new method of effectively producing new high perfor-mance propellant constituents for launch, orbit-orbit transfer and station keeping propulsion systems. The p ...
