Loch's Blair Proves VAMMP Technology
AUSTIN, Texas, Aug. 9 /PRNewswire/ -- ''Noted physicist Dr. Henry Blair released laboratory results today that show
Loch's proprietary VAMMP (Vacuum Multi-constituent Monitor for Plasma) technology has been proven,'' according to
Rodney Boone, CEO for Chemical Detection Technologies, Inc. (ChemTech) and its parent, Loch Harris, Inc. (OTC Bulletin
Board: LOCH - news).
Blair is expected to include these results as an integral part of his abstract and presentation at the prestigious Semi/Sematech's
AEC/APC Symposium in Vail, Colorado on September 14th. ''Blair's findings on this ultraviolet based system could have a far
reaching impact on the semiconductor manufacturing industry, and could easily challenge the economic significance of
ChemTech's landmine detector, the E.L.F. (Eliminate Landmines Forever),'' said Boone.
Blair's paper, ''Real-time, in situ, Plasma Process Monitoring'' describes the VAMMP as ''standoff, allowing in situ,
noninvasive, real-time monitoring'' using light in the ultraviolet spectrum as compared to E.L.F.'s use of X-ray. Boone said
results of validation tests received this week from ChemTech's Tucson, Ariz. lab in the ''Optics Valley'' show that Blair has
already proven the technology on which VAMMP is based. ''We know the technology is viable,'' Blair told Loch officials,
''based upon the large system we built previously for DOE (the U.S. Department of Energy). These evaluations were
necessary to assure that our miniaturization strategies are appropriate. The DOE systems are quite large and employ very
powerful excitation sources.''
''The results of these tests have shown that our efforts to miniaturize the already proven large scale technologies are
successful,'' Blair said. ''In addition to the VAMMP system, we can confidently investigate other possibilities where the sensing
and metrology of chemical constituents can be of great benefit in the commercial arena. The value of these results cannot be
over emphasized.''
''Optical management allows tomographic analysis of the plasma environment thus providing unique single wafer data in real
time,'' Blair explained. ''Discrimination and species recognition are managed by ChemTech's proprietary PC Sentry 93000(P)
neural net based software. The software package can provide closed-loop system high-level data. The system can also provide
alarm, digital or graphic operator reporting.''
''By the time of the symposium, said Boone, ''we expect to complete private funding negotiations now underway that will allow
us to proceed with the VAMMP prototype without incurring any long-term debt to the company. When the funding is in place,
we will 'fast-track' VAMMP to make it available within 9 months.''
With funding for the prototype expected to be competed soon, Loch Harris and ChemTech are aggressively seeking
non-financial partnerships in order to speed VAMMP's entry into the market.
