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 measures. The clean room is for the 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 nano-device fabrication

To build a sustainable society, it is essential to realize devices with low power consumption and high-speed operation based on nanotechnologies. In Center for Emergent Matter Science, researchers are developing quantum and spin devices by using state-of-the-art equipment with its best condition Our team is established to support the researcher’s activity by providing skillful expertise. We are responsible for the operation of equipment like lithography systems including electron-beam lithography systems, maskless UV photolithography systems, deposition systems like evaporators and sputters, dry and wet etching systems and observation system like scanning electron microscopy. 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 routinely.
