hombic Corporation Accepts University of Missouri
Proposal
VANCOUVER, British Columbia--(BUSINESS WIRE)--June 21, 1999-- Rhombic Corporation (OTC BB:NUKE)
announces that the company has accepted a proposal from the University of Missouri to use its laboratory facilities, technical
equipment, and personnel, to develop selected projects using the company's ''Forced Diffusion'' technology.
Purification of silicon carbide and gallium nitride wafer materials will begin July 1, 1999 under the supervision of Dr. Mark
Prelas. The wafers will be bought from U.S. manufacturers in two and three inch crystal sizes, and treated with the patented
''Forced Diffusion'' process.
The University proposal is to use the Rhombic technology ''to purify the gallium nitride of the unintentional oxygen and silicon
impurities incorporated into the structure, and to purify the silicon carbide wafers of the pollutants boron, nitrogen and oxygen.
The gallium nitride wafer is a blue laser generator, and silicon carbide is a major factor in high temperature, high speed
electronics. Both materials are light emitting diodes that can be modified to produce photovoltaic cells that assist in the
conversion of ultra violet light to electricity. Reducing the impurities in the wafers would give them an improved effectiveness
with a longer life span, and simplify the construction of photovoltaic cells.
According to the 1999 Industry Report, ''Silicon will remain the dominant material for substrates and wafers for the
foreseeable future with demand exceeding $7 billion in 1999. The push for ever greater performance at lower prices has
brought new wafer technologies into the market.''
Rhombic's patented ''Forced Diffusion'' process can be used to add to or to take out impurities from diamond, silicon carbide,
gallium nitride, and other special materials to modify the optical, chemical, electrical, and mechanical properties of those
materials.
Rhombic Corporation will announce soon that, beginning in September, 1999, its ''Forced Diffusion'' technology will be used
to develop a second project at the University Of Missouri's facilities.
