At the Hands-on-access Fabrication Facility, more than 150 equipment related to prototype development of various devices centering on MEMS are open to companies and universities to support their research and development activities and practical application. Users can use the equipment they need when they need it (charges are based on the equipment used and time). And companies and laboratories that do not have appropriate prototype development facilities dispatch engineers and students to create prototypes themselves. It reduces risks and costs. You can use the know-how accumulated at Tohoku University, and full-time staff will provide maximum support for device design, process design, equipment operation, etc. It is also possible to train engineers with actual development experience during prototype development. In the Hands-on-access Fabrication Facility, companies can also manufacture products under certain conditions. Since its start in 2010, it has been used by over 300 companies, and over 60 universities / public research institutes. To facilitate rapid prototyping of systems and test environments for microsystems the Prototype Lab. was established at the Hands-on-access Fab. In addition to machine tools such as 3D printers and cutting machines, more than 100 equipment related to electric assembly, mechanical assembly and evaluation can be used on an hourly basis in a 300m2 floor space. We also support prototyping of high-performance hardware that combines micro devices, such as semiconductor chips and sensors, with power supply and wireless communication functions. The lab provides the environment for system development and assembly, and to demonstrate the potential towards industrial products of micro devices/systems under development. Anyone can use it by registering to the Hands-on-access Fab. The usage will be supported by experienced staff.
