Patents Granted for Nanocolumn Technology
(Nanowerk News) IQE plc, a leading global supplier of advanced semiconductor
epitaxial wafer products and wafer services to the semiconductor industry, is
pleased to announce that NanoGaN Limited ("NanoGaN"), a wholly owned subsidiary
of IQE, has been granted two separate patents in relation to its nanocolumn
technology for the production of advanced blue and green lasers and LEDs.
Patent 2008-549935 has
been granted by the Japan Patent Office to NanoGaN and
protects the Group's proprietary nanocolumn technology for producing high
quality, free-standing gallium nitride substrates, which are critical for
manufacturing high quality blue and green semiconductor lasers and ultra high
brightness LEDs for Solid State Lighting ("SSL").
A second patent, No.2446471, has been granted by the UK patent office to protect
the process for manufacturing semiconductor devices such as laser diodes, LEDs
and solar cells, directly onto the proprietary nanocolumn platform.
The production of advanced blue and green semiconductor lasers and ultra high
brightness LEDs requires stable, high quality substrates with minimal defects to
increase yield and therefore reduce manufacturing costs.
IQE acquired NanoGaN in October 2009 with the aim of assisting in completing the
development of commercial products and thereafter transferring the technology to
its high volume production facilities.
IQE's acquisition of NanoGaN complemented and enhanced IQE's product portfolio
by accelerating the Group's strategic plans to develop a leadership position in
the emerging high growth markets for advanced laser projection, high definition
optical storage (including Blue Ray products), high resolution laser printing
and SSL for industrial, commercial and residential lighting. It is envisaged
that NanoGaN's core technology may also be used to further enhance IQE's leading
position in the supply of GaN products for high power RF applications.
Dr. Drew Nelson, Group CEO and President said:"Continuous innovation is one of IQE's key attributes that enables the Group to offer its customers the broadest portfolio of leading edge semiconductor technologies available.
"Adding these new patents to our existing portfolio, combined with strong
internal practices to protect intellectual property and know how, play a vital
role in ensuring IQE's position as a global leader in the manufacture and supply
of advanced semiconductor wafer products for the wireless, optoelectronic and
solar industry sectors."
