My guess would be that that liftoff (cleaving) technique from the MIT patent is not large-area production compatible. Of course if KOPN uses any kind of implanting machines we might be able to see it in their SEC reporting since they are very expensive. Probably they would farm it out, though. JF

Lift-off, Now vs Then They now use this phrase when describing the CyberDisplay fabrication process: This single crystal silicon is not grown on glass; rather, it is first formed on a silicon wafer and then lifted off as a thin film using our proprietary technology. I still happen to have an old Prospectus from the April 1992 offering. Remember the high-definition projector? Leafing through it, I noticed that back then they used a slightly different phrase (for Smart Slide): This thin film, single crystal silicon is not grown on glass; rather, it is first formed on a silicon wafer (using the Company's patented and proprietary ISE(tm) process) and is then transferred to glass. From the GLOSSARY, ISE(tm). Isolated Silicon Epitaxy. A technique for the manufacture of thin, high quality, single crystal silicon film on a wafer, with an inter-layer of silicon dioxide between the film and the wafer. CyberDisplay is essentially a smaller version of Smart Slide. The reference to ISE(tm) is no longer included, nor is it mentioned anywhere else in the more recent documents. Has ISE melted away to nothing? WT
