Because they've managed to navigate the field trials, and generate initial sales, I hold a very small position. We are talking a whole 100 shares here.

What I've seen happen to small companies is they have technology, sales and production capability, but can't ramp quickly enough to obtain breakeven before running out of working capital.

So I have to ask, if their sales/quarter are in the two digit area, how are they going to obtain breakeven with their low utilization rate? What rate of production would push them beyond breakeven? These sound like your typical business plan questions.

Probably the old chicken and egg thing. Volume sales can't happen unless they demonstrate production capabilities. But they also have to demonstrate financial viability. Cell Site operators don't want to install equipment from a company that might not be there two years hence to service it.

Put this in the FWIW semi-related department. Two inventions follow. My 2 one cent questions are, "Is this new or old news?" and "Does it have any application relative to SCON's manufacturing process?" — HerbVic

Chemically Tailored Corrosion Resistant High-Tc Superconductor Thin Film
Structures and Devices

DESCRIPTION

This invention relates to new formulations and methods of deposition of chemically stable (corrosion
resistant) high-Tc superconductor thin film structures and devices. Operation would be at liquid
nitrogen temperatures, as opposed to conventional superconductor operation at liquid helium
temperatures - liquid nitrogen coolant is cheaper than helium and more easily utilized. New formulations
of high temperature superconductors based on YBa2Cu3O7 have been identified which exhibit vastly
improved processing characteristics. This invention relates to both new formulations of these
superconductors as well as methods for their deposition in thin film form. Newly identified materials
exhibit both excellent superconducting properties (i.e. high Tc and Jc) as well as excellent
processability. These cation substituted materials are less prone to environmental degradation and
oxygen surface loss and less subject to oxygen electromigration problems. Collectively, these enhanced
materials characteristics make the new formulations attractive replacement candidates for the parent
compound, YBa2Cu3O7.



APPLICATION

This invention may be useful in the preparation of the following types of circuits and devices:
interconnects for hybrid semiconductor/superconductor circuits; digital Josephson technology; passive
microwave devices; superconducting quantum interference devices; superconducting field effect
transistors; high-Tc bolometers; and superconducting flux flow transformers.

* Superconducting transition temperatures above 77 K (78 <Tc<92).

* Jc comparable to YBa2Cu3O7 when changes in Tc are accounted for

* 100 fold reduced environmental degradation rates relative to YBa2Cu3O7

* Reduced problems with galvanic corrosion near metal contact layers

* Reduced problems with oxygen electromigration

* Higher reproducibility for high-Tc devices

Precise, Atomic Level Control of the Interfacial Properties of Superconductors
through the Spontaneous Chemical Adsorption of Monolayer Film



DESCRIPTION

A new method has been invented for the spontaneous adsorption of monolayer films (composed of a
certain class of molecules) onto the surfaces of superconductors. Previously, an effective method for
the direct chemical attachment of molecular or polymeric layers to the surface of superconductors did
not exist. The attached molecular or polymeric layers are of vital importance in determining the final
interfacial properties of the superconductor structures and devices. With this invention, the
surface-modification method is simple and easily reproducible using common lab equipment and
reagents. The result is precise, atomic level control of the interfacial properties of high-Tc
superconductor systems. Specifically, defect-free and anti-corrosion layers for both thin film and bulk
ceramic high-Tc structures can be generated in a simple fashion. These layers can be used to extend the
lifetimes of high-Tc structures. In addition, methods for lithographic processing of high-Tc devices can
be improved and/or optimized, and the adhesion of protection layers for the use of packaging the
superconductor structure can be improved.



APPLICATION

The new method may be used to fabricate superconductor devices, anti-corrosion layers, and adhesion
layers.
