センター長の挨拶
吉田 陽一
「産業科学ナノテクノロジーセンター」は、原子・分子を積み上げ
材料を創製するボトムアップナノテクノロジー、材料を極限まで削り
ナノデバイスを作製するトップダウンナノテクノロジー、さらにそれ
らの融合による産業応用を目指したナノサイエンス・ナノテクノロジ
ーを推進することを目的として、2002 年に産業科学研究所に設置さ
れた全国初のナノテクノロジーセンターで、今年度で 11 年目を迎え
ました。
設立当初は、専任 3、所内兼任 7、学内兼任 3、国内・外国人客員 3
の 16 研究分野からなる 3 研究部門制で発足した当センターですが、
2003 年にはナノテクノロジー総合研究棟が完成し、全学のナノテクノロジー研究を推進する
ためのオープンラボラトリーの運用も開始されました。さらに、2006 年にナノ加工室が設置
され、2009 年の産業科学研究所の大幅な改組に伴い、専任 6 研究分野を中心とした新しい組
織に充実強化されました。さらに、2010 年には文部科学省の低炭素研究ネットワークの大阪
大学サテライト拠点が設置されました。
また、産学官の学外ナノテクノロジー研究者のための共同施設として、2002 年のセンター
設立当初に、ナノテクノロジープロセスファンドリーが設置され支援活動を開始しました。
この活動は、2007 年には阪大複合機能ナノファウンダリへ、さらに 2012 年には、ナノテク
ノロジープラットフォームに引き継がれており、現在、
「微細加工」および「分子・物質合成」
の２つの重要な役割を果たしています。
現在の産業科学ナノテクノロジーセンターは、専任 6 研究分野を中心として、所内兼任 3、
学内兼任 6、国内・外国人客員 3 の 18 研究分野からなり、さらに、ナノテクノロジーに特化
した供用最先端機器を設置するナノテク先端機器室が設けられています。幅広くハード、ソ
フト、生体材料分野においてトップダウンとボトムアップナノプロセスの融合によるナノシ
ステムの創成、さらに、理論および評価との研究融合による新たな展開を図ることで、ナノ
テクノロジー研究を学際融合基盤科学技術へと発展させ、同時に学内・国内・国外の多彩な
ネットワークを構築して、ナノテクノロジー研究の拠点となることを目指しています。

編集後記
年次報告書、Vol.12 を発行いたします。早や、発足以来 12 年が過ぎ、
当センターの陣容も年々充実してきました。その結果、多彩な優れた成
果を生むに至っています。編集するに当って、成果の内容を吟味すると
同時に、更なる発展を目指し、構成員個々の責任を痛感するところです。
