Advances of Computer Science Technology ? Proposal of 3D-Electrode Structures Based on a Stereolithography-Based 3D-Printer ?

Abstract We have succeeded for the first time in fabricating threedimensional electrode structures by a stereolithography - based 3D-printer. 3D-printer technology is an innovative application brought by the computer science technology progress. In order to minimize the area taken by the electrical connections, we designed buried electrode structures. As a fundamental study, various shapes of mesa type electrodes have been designed, fabricated and characterized. For some structure shapes, the resistance between the electrode and the neighbor area was higher than 40MΩ, which reached the measurement limit of our resistance meter (multimeter). Thus, excellent electrical isolation has been obtained. Within four electrode structures, two of them performed a high electrical isolation.
