• FD-SOI substrates to be produced in high volume at multiple sites around the world
thanks to manufacturing and licensing strategy
• Collaboration between silicon leader and SOI leader brings to the market a large volume
wafer supply meeting 22FD-SOI specifications
• Strong FD-SOI industry support now includes extended IP and design services as well as
multiple substrate suppliers, ensuring high-volume manufacturing capacity

Bernin (Grenoble), France, July 14, 2015 — Soitec (Euronext), a world leader in designing and
manufacturing semiconductor materials for the electronics and energy industries, welcomes
GLOBALFOUNDRIES’ industry- first 22-nanometer fully depleted silicon-on-insulator (SOI)
technology platform (22FDX ) as the latest advance in the FD-SOI ecosystem. FD-SOI process
technologies are based on ultra-thin SOI substrates manufactured with Soitec’s industry-standard Smart
Cut™ technology. Soitec’s 300-mm FD-SOI substrates are ready now for ramp-up production with the
capacity to meet industry forecasts, thanks to the company’s two large, state-of-the-art 300-mm facilities
in Europe and Singapore. An additional volume of identical substrates will be available from the silicon-
wafer world leader Shin-Etsu Handotai Co., Ltd. (SEH), a Smart Cut licensee. Both wafer suppliers are
reportedly ready to increase capacity as needed.

All of this has been possible thanks to the combination of many years of Smart Cut expertise, proven
high-volume manufacturing at multiple sites as well as cooperation between Soitec and SEH to enable a
large-volume supply of high-quality silicon wafers and SOI manufacturing. The strong collaboration
between the silicon leader and the SOI leader brings to the market a large volume wafer supply meeting
22FD-SOI specifications.

Today’s news represents a major step in the FD-SOI roadmap for 22-nm processing. According to
GLOBALFOUNDRIES, its 22FDX technology will offer significant performance and cost benefits for
applications demanding low-power and high-performance requirements with possible analog and radio-
frequency integration. The technology is ideal for the low to mid-range mobile and wearable device
markets, while enabling a new generation of system-on-chip (SOC) technologies for the rapidly evolving
Internet of Things (IoT). Other markets include consumer multimedia, industrial and automotive
applications.

“GLOBALFOUNDRIES' announcement is a key milestone for enabling the next generation of low-power
electronics and we are very pleased to be GLOBALFOUNDRIES' strategic partner,” said Paul Boudre,
CEO of Soitec. “Our ultra-thin SOI substrate is ready for high-volume manufacturing of 22FDX
technology. With our two fabs and our worldwide licensing strategy, the market will enjoy all of the SOI
wafers it needs for strong adoption. The markets we are addressing with this product will be key
contributors to Soitec’s growth.”

“SEH welcomes this development, bringing FD-SOI products to the industry, and we look forward to the
continuation of our work in extending the global supply chain for FD-SOI,” said Nobuhiko Noto, general
manager of SOI Division at SEH. “We are very glad to be engaged in supporting the growth and
development of the FD-SOI market, both as a leading bulk wafer supplier to Soitec as well as with our
own FD-SOI wafer supply.”

The performance, power consumption, and cost benefits of FD-SOI have been proven, and FD- SOI is
expected to go into a high-volume production phase. According to Dr. Handel Jones, CEO of IBS, Inc.
“Multi-source supply chain for substrates has been established, and wafer volumes can potentially be one
million per year and more in the future. We are confident that Soitec and its licensing strategy will be able
to supply the substrates required to allow FD-SOI wafer volumes to reach their potential.”

The global FD-SOI ecosystem continues to grow with the participation of more leading semiconductor
foundries. In May 2014, Samsung announced the signing of a comprehensive agreement with
STMicroelectronics on 28-nm FD-SOI technology for multi-source manufacturing collaboration.
The strong industry support now includes multiple leading foundries, fabless adopters, IP providers, chip
equipment suppliers and EDA vendors.
