  • Abstract
    A CMOS LSI-based flexible neural stimulation device application with new fabrication technologies has been developed. The device was designed for application in retinal prosthesis. The device is based on multichip architecture, which enables the LSI-based stimulation device to be flexible. A fabrication process of arrayed bulk Pt electrodes, and a packaging structure of LSI chips with flip-chip bonding technology have been developed. These features provide the fabricated device with a lifetime of ten days in saline solution
