| Nikon Ships Next-Generation Electron Beam
Stepper to Selete for 65 nm Development
Belmont, Calif., July 7, 2003 -Nikon has shipped
its first electron beam (EB) stepper, the NSR-EB1A, to Semiconductor
Leading Edge Technologies Inc. (Selete) in Tsukuba City, Japan.
The system shipped to Selete is the world's first full field
electron projection lithography (EPL) tool and will initially
be used for advanced 65 nm development. Nikon has taken the lead
in the development of next-generation lithography systems with
the shipment of this system and with R&D efforts evaluating
and developing other technologies including immersion ArF, fluorine
(F2) and extreme ultra-violet (EUV).
EB systems up to now have performed exposure by moving a single
electron beam as if writing with a pen, but this process is extremely
slow. Nikon has succeeded in increasing the writing speed by
exposing an area 2500 times larger than earlier systems using
sub-field shots that are 250 microns square, thereby achieving
fast processing times. The first system will achieve 7 to 10
wafers/hour for 300 mm wafers and the mass-production system
will achieve 15 to 20 wafers/hour. In the past, electron beam
lithography systems produced less than one wafer per hour.
The price is expected to be slightly higher than a leading-edge
Argon-Fluorine (ArF) stepper. Although the system is more expensive,
it has a significant advantage in that expensive phase-shift
masks are not needed, and mask cost can be greatly reduced by
using standard stencil masks.
