a

semiconductor materials manufacturer that produces high-quality monocrystalline silicon
wafers used as materials for circuit boards in the manufacture of semiconductors. The
company’s two plants, situated in Phoenix, Arizona and Albuquerque, New Mexico,
produce polished wafers and epitaxial wafers. The company produces only 200 mm
wafers and in recent years has been focusing on discrete wafers for power semiconductors
used for current control and other applications. Going forward, our tasks will be to
continue supplying high-quality silicon wafers that meet the demands of customers and
preserving our price competitiveness as much as possible amid the ongoing trend toward

environmental improvement initiatives as one of its highest priority tasks in undertaking business operations
and carries out company-wide improvement activities.
SPX manufactures 200 mm silicon wafers for semiconductor products and operates two production bases
with over 600 employees in the United States. The company’s silicon wafers are utilized as a material in
semiconductor industries and make significant contributions to electric power savings worldwide through
their application in products used in various types of electronic devices. In contrast, the manufacture of these
wafers also creates an environmental load that includes the consumption of large volumes of energy and

and waste materials. Under these circumstances, the company is building
an environment management system based on ISO14001 and is utilizing this structure to ensure it can curb
the impact of its business operations on the environment to the greatest extent possible. Moreover, SPXis
enhancing its monitoring and checking system for complying with environment-related laws in the United
States and is also making efforts to promote recycling. As part of its five-year plan, from 2005 the company
undertook initiatives for reducing emissions of hazardous waste as well as for cutting the use of industrial
water and electricity and these efforts yielded major achievements To attain even further reductions in the

The United States, where we undertake our business operations, is said to be a mass production and mass
consumption society. Up to now, the United States has had an image of giving relatively little consideration to
the environment. However, this situation is also changing along with rising environmental awareness globally.
Looking ahead, we will continue reducing the environmental load resulting from our business activities and
provide high-quality silicon wafers to realize a low-carbon and recycling-oriented society.

Replacement of boilers at the Phoenix Plant
At the Phoenix Plant, in 2008 we replaced old-model boilers that had poor efficiency with high-efficiency new boilers, which
enabled us to reduce the amount of natural gas used.
Replacement of electric lights inside the Albuquerque Plant
At the Albuquerque Plant, in 2009 we replaced older electric lights with poor efficiency with high-efficiency new electric lights,
and thereby reduced the amount of electricity used.
2. Reduction of waste material
We switched electronic device waste processing companies to those business operators that assure 100% compliance with the Basel
Convention. By doing so, we are able to prevent electronic device waste from being unlawfully processed after the waste leaves our
plants.
3. Reduction of water consumption
Water used for production at the Albuquerque Plant is subsequently reused as irrigation water on the plant grounds. As a result,three
million gallons of water was reused in this manner in 2010.
