IceMOS Technology Closes $22 Million Series E
Investment
to Fund Launch of New
Power
Semiconductor Device Technology mSJMOSTM
Paradise Valley, Arizona –
April 2, 2025 - Semiconductor manufacturer, IceMOS Technology Corporation
today announced it has completed Series E funding from a London-based investor, 57 Stars LLC , and
earlier stage USA investors.
The company headquartered in Paradise Valley, Arizona, has a manufacturing center of excellence located in Northern Ireland, an advanced research
innovation center in Arizona, and a design center in Tokyo, Japan. IceMOS Technology is an industry-leading
developer of next generation silicon power devices. These products, called mSJMOSTM, are developed using a novel semiconductor technology
based on IceMOS Intellectual Property of which the company holds over 70
patents. The silicon-based mSJMOSTM, exhibits a new phenomenon resulting from
the integration of Silicon MEMS
manufacturing techniques with mature node CMOS Super-junction Power MOSFET
structures resulting in power
MOSFETs that deliver dramatic semiconductor energy efficiency.
The investment, which values IceMOS at a market capitalization of $110
million USD (£85million) post money, will enable IceMOS to increase
strategic manufacturing in Northern Ireland, device design capability, applications engineering, marketing and sales worldwide as it starts preparation to launch mSJMOSTM platforms.
“Our sensing and power technologies are paving the way for more energy-efficient and CO2-saving solutions that support decarbonization,” said Dr. Samuel
J. Anderson, MBE, IceMOS Technology Founder
and Chairman. “Products
based on this advanced technology represents a new class of semiconductors,
essential to serve the efficiency demands of the massively complex market
segments like artificial intelligence (AI), internet of things (IoT), big data,
renewables wind and solar, electric vehicles and aerospace applications.
The merging of mSJMOSTM structures and MEMS
manufacturing techniques presents a revolutionary silicon-based technology that
can compete with wideband gap devices at 650 Volts, 750Volts, 900Volts, and 1200Volts.”
IceMOS will
be expanding its global workforce to more
than 100 employees on post funding. IceMOS is pleased to announce that
Niall Lyne has accepted the position of IceMOS Chief Operating Officer and
Executive Vice President, Global Sales. Niall an Industry veteran held numerous
positions with Analog Device, Inc., Intersil and more recently Renesas
Electronics. In this position, he will be responsible for optimizing company
objectives, operations, and revenue growth.
The new Investors in the IceMOS Series E attended the Northern
Ireland Investment Summit in September 2023 which was a collaboration by the
Department for Business and Trade,
the Northern Ireland Office, and Invest Northern Ireland, which hosted around
200 investors from across
the world to visit Belfast
with the aim of turbocharging inward investment into all corners
of Northern Ireland.
Secretary of State for Northern
Ireland Hilary Benn said: “Northern Ireland’s track record of delivering innovation, its
supportive business environment, competitive operating costs and the creative
ingenuity of its people make it an attractive destination for businesses of all
sizes to start up and scale up.
“Northern Ireland has huge
potential for significant economic growth, so it’s great to see IceMOS secure
this funding as a result of the Northern Ireland Investment Summit, leading to
investment and job creation.”
Dr. Caoimhe Archibald, Minister for the Economy, added: “IceMOS Technology’s multi-million funding success showcases
the North’s strengths in advanced manufacturing and engineering. This
investment highlights the confidence global investors have in the North and
aligns with my vision to drive innovation, productivity, and technological
advancement. The 2023 Investment Summit played a key role in showcasing the
opportunities here and it’s encouraging to see significant outcomes like this.
I look forward to seeing IceMOS continue to push the boundaries of
semiconductor technology, creating high-value jobs in West Belfast and
pioneering solutions in sectors from AI to renewable energy.”
Bernard McGuire, Managing Director
of 57 Stars LLC: “IceMOS’ new architecture for silicon
semiconductors represents break-through technology for power management systems
in high-growth sectors such as electric vehicles and data centers," said
Bernard McGuire, Managing Director of 57 Stars. ‘’The hiring of industry
veteran Niall Lyne both validates the strength and potential of its innovative
products and enhances the management team to start scaling the business.” 57
Stars is the largest investor in this round of financing, having committed $7.5
million dollars. McGuire further commented: “Given the company sits squarely in
our sustainability and technology focus sectors, 57 Stars invested in IceMOS
out of multiple private equity funds we manage and are thrilled to be
partnering with and supporting the Company at this pivotal moment for its
growth and development.” 57 Stars was supported by EY on
financial and tax due diligence, Tughans LLP and Purrington Moody Weil LLP on
legal advisory, and SLR Consulting on environmental, health, and safety (EHS)
due diligence assessment.
