Plasmons Power Patterning

Facebook X LinkedIn Email
BERKELEY, Calif., Oct. 23, 2008 -- A new lithography process that resembles a needle playing an album on a traditional LP turntable uses plasmonic lenses as "optical styluses" and could make microprocessors much smaller and more powerful and create disks that hold 10 to 100 times more data. By combining metal lenses that focus light through the excitation of electrons -- or plasmons -- on the lens' surface with a "flying head" that resembles the stylus on the arm of an old-fashioned LP turntable and is similar to those used in hard disk drives, the researchers at the University of California, Berkeley, were able to create...Read full article

    Glossary
    diffraction
    As a wavefront of light passes by an opaque edge or through an opening, secondary weaker wavefronts are generated, apparently originating at that edge. These secondary wavefronts will interfere with the primary wavefront as well as with each other to form various diffraction patterns.
    light
    Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
    lithography
    Lithography is a key process used in microfabrication and semiconductor manufacturing to create intricate patterns on the surface of substrates, typically silicon wafers. It involves the transfer of a desired pattern onto a photosensitive material called a resist, which is coated onto the substrate. The resist is then selectively exposed to light or other radiation using a mask or reticle that contains the pattern of interest. The lithography process can be broadly categorized into several...
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    nanometer
    A unit of length in the metric system equal to 10-9 meters. It formerly was called a millimicron.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
    photoresist
    Photoresist is a light-sensitive material used in photolithography processes, particularly in the fabrication of semiconductor devices, integrated circuits, and microelectromechanical systems (MEMS). It is a crucial component in the patterning of semiconductor wafers during the manufacturing process. The primary function of photoresist is to undergo a chemical or physical change when exposed to light, making it selectively soluble or insoluble in a subsequent development step. The general...
    wavelength
    Electromagnetic energy is transmitted in the form of a sinusoidal wave. The wavelength is the physical distance covered by one cycle of this wave; it is inversely proportional to frequency.
