Smaller, faster, cheaper, better.
These words are a driving force in research
and development - and with good reason. The computer revolution
of the past 30 years taught us that the power to change the world
often comes in tiny packages.

renovated to allow fabrication of microelectromechanical devices.

Today, engineers and scientists are learning how to build probes,
sensors, switches, engines and other machines small enough to fit
through the eye of a needle. Like computer chips, these devices
are produced using silicon-wafer techniques. Unlike computer chips,
which are purely electronic, the tiny machines can contain microscopic
gears, levers and pulleys, mirrors, lenses and other components.
The new generation of microdevices will be able to sense, act and
communicate. The applications are virtually limitless, ranging from
communications to transportation, from consumer devices to medicine.
Imagine a pocket-size device that functions as a cell phone,
personal computer, TV and global position tracker. Or wearable
medical monitors that administer medication as needed. Or sensors
the size of a worker's button capable of identifying toxic chemicals.
"Micromachines will become ubiquitous," predicts First
in Class Director Donald Boyd. "They will find their way
into devices that haven't even been dreamed of yet."
Microsystems are a key research area for RIT. Some three dozen
faculty members from several colleges are working in various aspects
of this effort, which has been identified as one of the university's
First in Class Initiatives. In May, RIT's efforts
received a huge boost with the award of $14 million through the
New York Office of Science, Technology and Academic Research (NYSTAR)
to create a Strategically Targeted Academic Research (STAR) Center
(see story, page 11).
The timing couldn't be better. The world is poised on the verge
of a microsystems revolution that could dwarf the development
of the microprocessor. The MEMS Exchange, a manufacturing umbrella
organization, is predicting annual sales of $100 billion in micromachines
by the end of the decade.

In truth, micromachines are pretty big already. Although consumers
may be unaware of their presence, microelectromechanical systems
MEMS are used in many products, notably automobile air bag activators,
ink-jet printer heads and high-end projectors. Delphi Automotive
Systems, Motorola, Hewlett-Packard, Sony, Texas Instruments and
Xerox are among the many players involved in highly competitive
research and development in this arena. At this point, no company
has cornered the overall market.
Microsystems research is a natural area for RIT involvement.
One strength is RIT's longstanding leadership in microelectronics.
MEMS devices are an extension of integrated circuit manufacturing
techniques.
"We understand much of the basic technology of microsystems already,"
says Harvey Palmer, dean of the Kate Gleason College of Engineering,
noting that RIT's microelectronic engineering department has operated
a chip-making facility since 1986. "The challenge is to use this
technological know-how to develop valuable products. RIT has an
advantage in this, as well: The university has a long tradition
of working with industry partners on practical uses for new technology."
"We take research and stretch it to enable new products," explains
Paul Petersen, director of the design, development and manufacturing
area of RIT's First in Class effort. "That's what we're geared
to do."

In the microsystems area, partnerships are already formed. RIT is
working with companies including Kodak, Xerox, Corning, and others
as well as with other universities and government agencies. The
industry partners, in conjunction with New York state, are working
to establish a Rochester Center for Excellence in Photonics and
Microsystems. The research would focus on optics, fiber optics and
photonics.
"Given its rich and relevant portfolio of advanced technologies
from microelectronics to reliability engineering to statistical
process control and integrated manufacturing systems, RIT forms
a master link in the chain of universities across the Empire State
that will collaborate through Infotonics," says David R. Smith,
director of production systems engineering and technology, Imaging
Materials and Media Platform Center, Eastman Kodak Co.
As with all of the First in Class Initiatives,
students are working with the MEMS researchers, thus the university's
academic program is enhanced. Under development is a new Ph.D.
program in microsystems. This program, modeled after RIT's unique
imaging sciences Ph.D. program, would be highly multidisciplinary,
involving virtually every engineering and science discipline.
Meanwhile, a state-of-the-art facility for microsystems research
is being designed. Contiguous with and complementary to the existing
microelectronic engineering lab, it will provide researchers with
the ability to fabricate MEMS devices. Construction is expected
to begin in spring 2002.

"The expansion will provide capabilities new to RIT," says Karl
Hirschman, director of the lab and a 1990 microelectronic engineering
graduate. "The renovation also will enhance our current capabilities.
We'll continue to provide outstanding educational opportunities
to our students, as well as fill the needs of the researchers."
RIT is poised to surf the crest of this promising new wave of
technology. It's likely to be an exciting ride and a long one.
As Paul Petersen notes, "Microsystems promise to have an impact
comparable to the integrated circuit. In 10 to 20 years, virtually
all products will employ a microdevice. It's a trite saying, but
we will be limited only by our imagination."
