Using light to inscribe tiny nanoscale plastic parts

By 12 May 2010

One of the biggest obstacles in microscopy and in micro-fabrication is the so-called diffraction limit. This basic law says that the resolution (or sharpness) of an image cannot be better than approximately half the wavelength of the light waves being used to make it. Similarly, when light is used to inscribe patterns on microchips — a standard process known as lithography — these features can …
