Outline

Our mission is to develop novel technologies with a wide range of applications in nanoscience and nanotechnology and to support the users in RIKEN for nanometer-scale fabrication and the characterization of specimens. We are responsible for the operation of the facilities including the clean room and the chemical rooms with suitable safety measure. The clean room is for fabrication and characterization of nanometer-scale devices and the chemical rooms are for those of wet samples for chemistry and biology. In the clean room and the chemical rooms, more than 30 apparatus have been installed and are open to the users. We are also responsible for the education of the users.

Supporting researchers for nanometer-scale fabrication

To build a sustainable society with environment friendly device, it is essential to realize energy effective devices and faster information process. To realize such devices, the researchers in the Center for Emergent Matter Science are enthusiastically pursuing to develop quantum devices, spin devices and quantum computers. In building such devices, highly sophisticated equipment and support for keeping best condition of the equipment are required.

Our team is established to support the researcher’s activity by providing skillful expertise. We are responsible for operation of the equipment like lithography systems including an electron beam lithography, a maskless UV photo lithography system, deposition systems like evaporators and sputters, dry and wet etching systems and observation system as scanning electron microscopy and for keeping them in the best condition. We instruct users in the usage of equipment and provide technical information in fabrication. With our effort, the researchers are now able to fabricate and characterize various devices in the range of 10 nm – 10 µm tirelessly.
