Gamma ray lithography

X-ray lithography originated as a candidate for next-generation lithography for the semiconductor industry , with batches of microprocessors successfully produced. Having short wavelengths (below 1 nm), X-rays overcome the diffraction limits of optical lithography, allowing smaller feature sizes. If the X-ray source isn't collimated, as with a synchrotron radiation, elementary collimating mirrors or diffractive lenses are used in the place of the refractive lenses used in optics. The X-rays illuminat… WebGamma rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum.
