“Bow Tie” Enhances EUV

Facebook X LinkedIn Email
DAEJEON, Korea, June 9, 2008 -- According to KAIST reseachers in Korea, a bow tie-shaped gold nanostructure on a saphire substrate can enhance the intensity of femtosecond laser light pulses by two orders of magnitude.  The devise is smaller and cheaper than existing systems and might allow a laptop-sized extreme ultraviolet (EUV) source to be used in high-resolution biological imaging, advanced lithography of nanoscale patterns and perhaps even X-ray clocks, which are being investigated worldwide to replace the current caesium atomic clocks for better time precision.

    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...
