STURBRIDGE, Mass. -- A new lens design originally created for applications in astronomy, and based on the eye structure of a lobster, holds promise in the etching of ultrasmall electronic components on a chip. Nova Scientific Inc. and a team from the University of Leicester, UK, invented the microchannel plate, or "lobster-eye" lens, and hope to use it to make electronic components much smaller than 0.18 µm -- the smallest that has been produced using x-rays -- for a fraction of the cost of current x-ray technology. In traditional photolithography, a collimated beam of visible light shines...Read full article

    astronomy
    The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
    microchannel plate
    A device used as an electron multiplier when photons at the ultraviolet and x-ray wavelength are incident upon it. Resembling a thin fiber optic faceplate, the MCP has the interior surface of each hollow fiber coated to produce substantial electron amplification over its length. As a photon strikes the first surface on the MCP, it is converted into an electron. This electron then strikes a secondary surface knocking free several more electrons, which then strike a third surface eventually...
