SEN Corporation to Become Wholly Owned Subsidiary of Sumitomo Heavy Industries
Sumitomo Heavy Industries resolved at a meeting of its Board of Directors on February 26, 2009, tomake SEN Corporation, an SHI and Axcelis Company (hereinafter, “SEN”) a wholly owned
subsidiary of Sumitomo Heavy Industries (hereinafter, “SHI”). SEN was established as a joint
venture company between SHI and Axcelis Technologies, Inc. (hereinafter, “Axcelis”) in the UnitedStates. The details of the resolution are described below.
1. History of SEN becoming a wholly owned subsidiary of SHI
In 1983, SHI entered into the business of ion implanters, a type of semiconductor, with theestablishment of SEN (formerly Sumitomo Eaton Nova Corporation), a 50-50 joint venturewith the US-based Eaton Corporation. In 2000, Eaton Corporation spun off its semiconductorbusiness and formed a new firm called Axcelis. The new company replaced Eaton Corporation
as the controller of shares in SEN.
Axcelis recently proposed to sell its 50% stake in SEN along with grant of license andnon-exclusive sales rights for ion implanters that are jointly held by Axcelis and SHI. After
negotiations by both companies, an agreement was reached whereby SHI would acquire theAxcelis-held shares and related interests for a total price of ¥13 billion. By becoming awholly-owned subsidiary of Sumitomo Heavy Industries, it will be possible for SEN to be
managed in a more agile manner, and the synergies that exist between SEN and the cutting-edge
technologies of the Group will become more evident.
