DENSO Licenses SJ MOS Transistor

DENSO Licenses SJ MOS Transistor 
- DENSO's transistor fabrication technology enables more energy-efficient and
smaller power units - 
Kariya, Japan, Feb 27, 2013 - (JCN Newswire) -  DENSO Corporation today
announced that it has signed a licensing agreement for its Super Junction
Metal-Oxide-Semiconductor (SJ MOS) transistor manufacturing technology, with
Tokyo-based New Japan Radio Co., Ltd - a company that manufactures
semiconductors and electronic components. DENSO's new technology realizes
a power semiconductor device with the world's lowest level(1) of
on-resistance(2), which results in an improvement in efficiency and a smaller
power device. 
Developed with DENSO's own technology, the new SJ MOS transistor can be
used to increase the energy efficiency of personal computer AC adapters,
servers, in-vehicle power converters, and other devices, while also making them
smaller in size. Also, the new transistor involves fewer fabrication steps than
those made by conventional SJ MOS fabrication technologies, which reduces the
manufacturing cost. 
DENSO is committed to further expand its licensing business of the SJ MOS
transistor technology in the global market. 
About DENSO's SJ MOS transistor fabrication technology 
DENSO has developed the trench-filling technology to fabricate SJ MOS
transistors. With this technology, micron-scale (micro-m: one millionth of a
meter) trenches are etched on the surface of a silicon substrate, then using
epitaxial growth(3), a thin-stripe structure of N- and P-type semiconductors
are formed. DENSO's own trench-filling technology allows finer
fabrication, which reduces the on-resistance and increases the switching speed
of SJ MOS transistors, thus reducing the size and power consumption of power
units, in-vehicle power converters, and other devices. 
About DENSO's semiconductor business 
In anticipation of the widespread use of automotive electronics, DENSO
established the IC Research Center in 1968. Since then, the company has
designed, developed, and produced in-vehicle semiconductor devices for more
than 40 years. DENSO will continue to develop more advanced semiconductor
technologies based on those it has already developed. 
(1) DENSO's survey of SJ MOS transistors as of February 2013
(2) The resistance value of a power semiconductor when activated (energized).
A lower value of resistance means less power loss and higher energy
efficiency.
(3) A technique to produce thin films from crystals on a substrate in a
chemical reaction.
