Technology Mix Spurs MRAM Breakthrough
Staff

Düsseldorf, Germany: Fabrication of
a magnetoresistive random-access
memory (MRAM) that integrates two
new technologies—spin transfer
switching and perpendicular magnetic
anisotropy (PMA)—was successfully
achieved by Toshiba.
MRAM, a next-generation, nonvolatile
semiconductor memory
device that offers fast random
write/access speeds, enhances
endurance in operation with very
low power consumption. MRAM
can theoretically achieve high-level
integration because the memory-cell
structure is relatively simple.
In making these advances,
Toshiba applied and proved the
spin transfer switching and PMA
technologies in a magnetic tunnel
junction, which is a key component
in the memory cell. Spin transfer
switching uses the properties of
electron spin to invert magnetisation
and writes data at very low power
levels. PMA aligns magnetisation in
the magnetic layer perpendicularly.
Toshiba also overcame the hurdle
of achieving the required precision
in the interface process and significantly
cut write power consumption.
In addition, to realise a miniature
memory cell based on PMA,
Toshiba optimised the MRAM’s
materials and device structure (see
the figure).
A switch in the switch arena
Dole, France: Following the sale of
ITT’s Switch division in France, the
newly formed, privately held company
C&K Components was founded.
It will combine the experience
of C&K Components of Newton,
Mass., USA; the Rudolf Schadow
Company of Berlin, Germany; and
the Jean Renaud switch company of
Dole, France.
TSMC Europe names president
Hsinchu, Taiwan: TSMC appointed
Maria Marced as president of
TSMC Europe. Before joining
TSMC, Marced was senior vice-president and general manager of
sales and marketing at NXP
Semiconductors (previously Philips
Semiconductors). There she contributed
to the creation of its new
brand entity, NXP, and was
involved in the company’s sale to a
private equity consortium.
Prior to joining Philips, she was
vice president and head of Intel’s
European operations.
Ms. Marced holds a PhD in
telecommunications engineering
from Universidad Politecnica de
Madrid, Spain.
Silicon solution eyes RF apps
Eindhoven, Netherlands: The
BFU725F microwave NPN transistor
is the first in a series of siliconbased
discrete solutions to be
launched by NXP Semiconductors.
The device is a blend of high
switching frequency, high gain, and
low noise that suits it for a variety
of RF applications.
According to NXP, the low noise
figure improves the reception of the
sensitive RF receivers found in various
wireless devices, such as GPS
systems, DECT phones, and satellite
radio. And, its high cut-off frequency
suits applications in the 10 to
30GHz range.
The BFU725F transistor was created
using NXP’s silicon-germaniumcarbon
process technology for discrete
components, the same process
used to develop monolithic ICs and
wideband transistors. The RoHScompliant
device is available now.
Award win for Burnett
London, England: The National
Microelectronics Institute (NMI), the
trade association for the U.K. and
Irish semiconductor industry, presented
its “Contribution to Industry”
award to Ian Burnett at the NMI’s
annual awards dinner in London.
Burnett, the managing director of
IDB Technologies and a director of
Jemi UK, the Joint Equipment and
Materials Initiative, was recognised
for his work in supporting new companies
in the sector. The award also
commended his guiding of new technologies
from the science base into
commercial applications.
The other NMI award winners
were: Energy efficiency, Freescale
Semiconductor; Start-up of the year,
Nanotech Semiconductor;
Innovation, ST Microelectronics
(Imaging Division); Services to training
and education, EDA Solutions;
Emerging technology company of
the year, DisplayLink; and
Manufacturing site of the year,
Zetex Semiconductors.
