Research and Development
Fujitsu's research and development focused on multimedia-related technologies, including
the systems, software, services and electronic devices that support the forthcoming
advanced network society.
In systems technology, Fujitsu successfully prototyped a 10-Gbps optical transmission system.
This system serves as the life line of broadband ISDN and enables the transmission of multimedia
information.
In software, Fujitsu developed a technique that analyzes existing COBOL programs and
automatically creates the application specifications needed for system reconstruction.
Fujitsu built a prototype of CyberCity, a virtual city on a computer network. The company
also promoted the development of network and interface technologies so that users can enjoy
a range of multimedia services offered via the virtual city.
In eletronic devices, Fujitsu established surface polishing technologies and
insulating film materials suitable for increasing the number of metal layers in 0.25 micron LSIs.
Beyond that, Fujitsu invented a new CMOS structure that maintains good transistor
performance at a gate length of 0.075 micron for memories and processors of the next century.
Our study of compound semiconductors resulted in the successful development of a GaAs
hetero-bipolar transistor, which exhibits high efficiency and produces high power on a low
3.5-volt supply. This new transistor is slated to be used in the next generation of digital
cellular phones.
Fujitsu established the Parallel Computing Research Facility in fiscal 1991 to promote
parallel processing research and bring together related know-how. The facility has developed
into an international research community with more than 240 registered users throughout the
world, and a range of parallel processing software has been developed. For further exploration,
the company installed an AP1000 highly parallel computer at Imperial College in the U.K.
Joint research is now under way with this well-established institute in the field of parallel
processing technology.
