She originally joined the IBM semiconductor plant in Sindelfingen, Germany, in 1983, starting with a three-year course of study in chemistry. Afterward she worked in the fabrication line for multilayer ceramic packaging, where she was promoted to Section Head in 1993. In 1996, Ms. Drechsler joined the Micro/Nanomechanics group at the IBM Zurich Research Laboratory, working on silicon micromachining and processing techniques for Millipede array chips and processing-related work for other department projects. She is currently responsible for the organization and operation of the department cleanroom.

Urs Dürig   IBM Research, Zurich Research Laboratory, Säumerstrasse 4, 8803 Rüschlikon, Switzerland (drg@zurich.ibm.com). Dr. Dürig received a degree in experimental physics and a Ph.D. degree from the Swiss Federal Institute of Technology, Zurich, in 1979 and 1984, respectively. He then spent a postdoctoral fellowship at the IBM Zurich Research Laboratory, working on near-field optical microscopy in the group of D. W. Pohl; he became a Research Staff Member in 1986. He then worked in the field of scanning tunneling and force microscopy, investigating metallic adhesion, growth morphology of magnetic thin films, and surface melting. In addition, Dr. Dürig made significant contributions to the instrumental development of dynamic force microscopy. In 1997, he joined the Micro/Nanomechanics group working on instrumental aspects and on characterizing tip­polymer interactions.

Walter Häberle   IBM Research, Zurich Research Laboratory, Säumerstrasse 4, 8803 Rüschlikon, Switzerland (wha@zurich.ibm.com). Mr. Häberle is a Development Engineer in the Science and Technology Department of the IBM Zurich Research Laboratory. In 1974, he joined the IBM semiconductor plant in Sindelfingen, Germany, for his education in physics. He was later promoted to Group Leader in the Quality Control Department of the semiconductor line. In 1987, he joined the IBM physics group of Prof. G. K. Binnig at the University of Munich, where he contributed to the development of AFMs for applications to liquids for investigating living cells. In 1995, Mr. Häberle transferred to the IBM Zurich Research Laboratory, where he was responsible for prototyping a new low-cost AFM instrument with good price/performance, which has since been commercialized by Seiko Instruments, Japan. In addition, he has been involved in various aspects of Millipede, including writing/reading experiments and scanning approaches for the 32 × 32 array chip.

Mark I. Lutwyche   IBM Research, Zurich Research Laboratory, Säumerstrasse 4, 8803 Rüschlikon, Switzerland (mlu@zurich.ibm.com). Dr. Lutwyche received a B.Sc. degree in physics from Imperial College, London, in 1986, and a Ph.D. from Cambridge University in 1992 in micromechanics and electron-beam lithography. Afterward he joined the Hitachi Advanced Research Laboratory in Japan for four years as a Visiting Scientist. During this time, he worked on a combined transmission electron microscope/scanning tunneling microscope, micromechanics, nanostructures, and single-electron transistors. In 1997, Dr. Lutwyche joined the Micro/Nanomechanics group of the IBM Zurich Research Laboratory as a Research Staff Member working on atomic force microscope systems for future data storage.
