Their own transfer technology is CLEFT. It is a marvel if they have achieved production quantities using CLEFT, with high quality at a reasonable cost {kopin}. However, the public releases from Kopin (including last year's Prospectus) provide no details about the transfer procedure now being used in CyberDisplay manufacture. Of course not—it's proprietary. They no longer refer much to CLEFT; instead they say that the lift-off procedure uses the company's Wafer Engineering technology. That could mean just about anything. Here is an alternative to CLEFT, available in production quantities from SOITEC: soitec.com In the paragraph about their Silicon-on-quartz and Silicon-on-glass Wafers, they even state that "wafers with a monocrystalline film of silicon-on-quartz or glass are used for manufacturing liquid crystal displays (LCDs) of small dimension and high resolution, a process which has traditionally used polysilicon." Download the data sheets for more information. If this is competitive with what Kopin is doing (?), then by working with SOITEC, other companies could enter the market. WT
