THE EXTENSION OF A NON-CONTACT POLISHING TECHNIQUE PREVIOUSLY DEVELOPED FOR IT-VI COMPOUNDS, IS PROPOSED FOR (100) GAAS WAFERS INTEGRATED CIRCUIT APPLICATIONS IN MIND. AN INITIAL TASK WILL BE TO CHARACTERIZE SUCH NON-CONTACT POLISHED SURFACES AND COMPARE THEM WITH CONVENTIONALLY POLISHED SURFACES. FOLLOWING SUCCESSFUL DEVELOPMENT OF THE TECHNIQUE, WE WILL INVESTIGATE THE FEASIBILITY OF SCALE-UP FO ...

NEAR-SURFACE DEFECTS IN SEMICONDUCTORS HAVE A PRIMARY INFLUENCE UPON DEVICE PROPERTIES, PARTICULARLY THE YIELD. IT WOULD BE VERY USEFUL TO BE ABLE TO MAP SPATIALLY THE DENSITY AND TYPE OF DEFECTS NEAR A SEMICONDUCTOR SURFACE EITHER AS A WAFER QUALITY CONTROL STEP OR TO SUPPORT DEVICE PHYSICAL EXPERIMENTS. CONVENTIONAL TECHNIQUES USED FOR THIS PURPOSE SUFFER FROM ONE OR MORE OF THE FOLLOWING LIMITA ...

THERE IS A NEED FOR A GOOD STRUCTURAL CERAMIC MATERIAL THAT CAN BE USED AT HIGH TEMPERATURES IN THE OXIDIZING AND CORROSIVE ATMOSPHERE OF TURBINE ENGINES AND THAT CAN BE FORMED ECONOMICALLY TO COMPLEX SHAPE WITH LOW WEIGHT. THE OBJECTIVE OF THIS RESEARCH PROJECT IS TO INVESTIGATE A NEW FAMILY OF CERAMIC COMPSITE MATERIALS THAT MAY MEET THOSE REQUIREMENTS. IT IS BASED ON CHEMICALLY VAPOR DEPOSITED ...

PROJECTILE PULSE GENERATOR (PPG) HAS BEEN CONCEIVED TO SATISFY ANTICIPLATED AIR FORCE REQUIREMENTS. THE PPG IS EXPLOSIVELY DRIVEN AND IS INTENDED TO MEET THE REQUIRMENTS STIPULATED IN THE SBIR

THE RAPID ADVANCES IN MICRO COMPUTER TECHNOLOGY AND THE MASS MARKETING OF THE PERSONAL MICRO COMPUTER HAVE RESULTED IN DRAMATIC COST REDUCTIONS IN HARDWARE AND SOFTWARE. ALSO, THE SIGNING OF THE AIR FORCE, NAVY AND MARINE MICRO COMPUTER REQUIREMENTS CONTRACT HAS RESULTED IN A DRAMATIC 50% REDUCTION IN THE COST OF MICRO COMPUTER SYSTEMS. ALL OF THESE FACTORS MEAN THAT IT IS NOW REALISTIC AND COST E ...

IN THIS PROGRAM, THE EFFORT WILL CONCENTRACTE ON ATTAINING A COMPLETE UNDERSTANDING OF THE PHYSICS INVOLVED IN INFERRING THE SHAPE OF THE FORWARD SURFACE OF A CARBON/CARBON NOSETIP FORM THE ECHO WAVESHAPE GENERATED BY A NULTRASONIC TRANSMITTER/RECEIVER MOUNTED ON THE BACK FACE. THE HIGHEST PRIORITY WILL BE FOCUSSED ON THE ABILITY TO IMPROVE THE INTERPRETATION OF PREVIOUS AND FUTURE FLIGHT DATA USI ...
