  • Patent number: 6444408
    Abstract: Polymerizable monomers having silicon containing groups that are transparent at 193 nm; and ethylenically unsaturated group are provided. Polymers from these monomers can be used in processes for forming sub-100 nm images with a chemically amplified, radiation sensitive bilayer resist. The bilayer resist is disposed on a substrate and comprises (i) a top imaging layer comprising a radiation sensitive acid generator and (ii) an organic underlayer. The bilayer resist can be used in the manufacturing of integrated circuits.

  • Patent number: 6295106
    Abstract: Novel liquid crystal display (LCD) structures for full-color liquid crystal displays using photoluminescent (PL) fibers. The new architectures simplify the LCD fabrication process by replacing complicated, time consuming photolithography steps for color filter fabrication to a low-cost, high-throughput fiber spinning technology. The new LCD architecture implementing the approach has a higher power efficiency than conventional LCDs. Three structures of LCD devices utilizing photoluminescent (PL) fiber arrays includes: a first structure having PL fiber arrays situated behind the LC shutter (relative to viewers); a second structure having PL fiber arrays situated on top of the LC shutter; and a third structure where the PL fiber arrays are located outside the LC cell. In one of these structures, the fibers not only photoluminesce, but also polarize incident light thus reducing LCD fabrication cost.
