'It's also a connection to ultrafast technology, because some of the same sources using ultra dot pulse are used for EUV radiation. There is interest in other wavelengths and it's worth exploring those as well, but the most demand at the moment is 13.5nm.'

On reflection: Keely Portway looks at some of the latest developments in optical mirrors--including a trend for larger sizes--and how the technology may develop further

The plasma emits EUV radiation at a wavelength of 13.5nm in all directions, which is then collected by a mirror, and focused and directed through the lithography system to expose the silicon substrate.

DRIVING MOORE'S LAW WITH C[O.sub.2] LASERS: C[O.sub.2] lasers could be used to produce the next generation of computer processors, experts said during the European Photonic Industry Consortium's Executive Meeting on Industrial Lasers

The current technologies for generating high power EUV radiation at 13.5 nm, referred to as laser produced plasma (LPP), employs the deposition of laser energy into a source material such as molten tin (Sn) droplets, creating ionized gas microplasma at electron temperatures of several tens of electron volts.

But the researchers found low levels of EUV radiation only account for about 30 per cent of the collapse, while the increase in CO2 levels account for another 10 per cent at most.

The book begins with coverage of EUV source requirements and the status of the technology, followed by a review of atomic data and descriptions of theoretical models of discharge-production plasma (DPP)- and laser-produced plasma (LPP)-based EUV sources, DPP and LPP designs, and alternative technologies for producing EUV radiation.

EUV Sources for Lithography

The NIST/DARPA EUV Reflectometry Facility consists of three parts: the Synchrotron Ultraviolet Radiation Facility (SURF III) [3] storage ring, which provides continuum EUV radiation; the monochromator; and the reflectometer sample chamber.

Towards high accuracy reflectometry for extreme-ultraviolet lithography

Since EUV radiation is absorbed by all materials, the lithography process must be performed in a vacuum and use reflective optics.

Can Lithography Go to the Extreme?

Unfortunately the radio data suggested that a dense concentration of cool hydrogen filled essentially all of our galaxy, making the ISM extremely opaque to EUV radiation.

Observing a partly cloudy universe

Analysis oi data from ROSAT's wide-field camera has produced a catalog of 383 sources of EUV radiation. Most of these sources correspond to white dwarf stars or to "active, late-type" stars (SN: 5/23/92, p.344).

Driving Moore's law with C[O.sub.2] lasers: C[O.sub.2] lasers could be used to produce the next generation of computer processors, experts said during the European Photonic Industry Consortium's Executive Meeting on Industrial Lasers

Finding a suitable source of EUV radiation for the tool has been one of the major challenges; the source must be compact, bright, and free of contaminating debris.
