IMRA America, Inc., a subsidiary of Aisin Seiki Co., Ltd., and DISCO
Corporation have agreed to collaborate in the development of new lasers and
processing systems for laser dicing of semiconductor materials.
IMRA America has supplied several hundred femtosecond fiber lasers* that are
now being used in semiconductor manufacturing facilities, delivering the high
reliability and stability required for 24/7 operation. Also, IMRA America is
the exclusive licensee of US Patent 5,656,186 by the University of Michigan,
essential for femtosecond and picosecond laser materials processing, which they
license to their customers.
In the future, both companies will together provide new solutions utilizing the
unique capabilities of femtosecond lasers, which minimize thermal effects in
* Femtosecond Fiber Lasers
These lasers emit pulses of light with a temporal duration on the order of
femtoseconds (1 femtosecond is 1 quadrillionth of a second) at a high
repetition frequency. A major advantage of femtosecond pulses is that the pulse
duration is so short it is possible to minimize thermal damage. Femtosecond
laser pulses can also create modifications within transparent materials without
damaging the surface.
