Micromechanical Component Production Via X-Ray Lithography and Precision Metal Plating @ University of Wisconsin-Madison
An interdisciplinary research team consisting of electrical and mechanical engineers will carry out fundamental research directed toward an improved understanding of processing technology for the fabrication of microelectromechanical devices. This research will use synchrotron based x-ray lithography in connection with 25 micron PMMA (poly methyl methacrylate) photoresist layers and fine-grained polysilicon mask blanks with optically defined absorber patterns made from one micron thick electroplated gold layers. The thick photoresist will be exposed on Aladdin, the Wisconsin synchrotron, and subsequent developing will produce vertical flank PMMA profiles with one micron minimum feature sizes. These structures will then be electroplated to provide micromechanical devices made from the materials used to electroplate the silicon. Additionally, research in plating will be aimed at creating deposits with repeatable and controlled mechanical properties and will focus on nickel, gold, cobalt-nickel, and silver-palladium alloys. The nickel- cobalt alloys are intended for bearing surfaces in microelectro- mechanical devices. The silver alloys address contact welding problems in microswitch applications. The proposed process is fundamental to micromechanics and, in particular, lends itself to actuator construction such as miniature gears and acceleration driven switches, in addition to numerous other potential applications.

United States-South Africa Study Group in Engineering Research and Education For the Manufacturing Industry @ University of Wisconsin-Madison
This award establishes a USA Study Group formulated to investigate engineering research and education issues related to manufacturing industries. In conjunction with a similar group funded by the Foundation for Research Development in South Africa, the interaction of the two groups will allow for a sharing of past experiences and visions for the future. The exchange focuses on human resources development issues, including programs designed to increase the number of educated engineers from population segments that traditionally do not select technologically oriented careers. Two-week visits in each other's country includes stops at representative educational institutions and the holding of focused workshops to develop reports identifying areas of possible further interactions.

Research On Micromechanics and Micromagnetics Based On X-Raylithography and Electrodeposition of Metal Structures @ University of Wisconsin-Madison
The proposed research is intended to exploit opportunities recognized in the development of the LIGA process for fabrication of microelectromechanical systems (MEMS). Direction is provided by potential commercial technology transfer, including improved MEMS for sensors and the creation of new classes of devices. A significant portion of the proposed research is in magnetics technology for MEMS. Design methods and constraints will be analyzed via electroplated magnetic structures. A cell designed linear magnetic actuator will be the primary test vehicle. The emphasis will involve output force per unit chip area considerations, speed and positional accuracy, as well as control electronics. Rotating magnetic motors will be constructed with compatible gear boxes. New microsensors such as magnetic proximity sensors will also be investigated.
