Retinitis pigmentosa and age-related macular degeneration

cause blindness due to the deterioration of photoreceptor cells. The retinal prosthesis has been developed to obtain the vision lost by these diseases. We have been developing a 3D-stacked retinal prosthesis chip to enhance the performance of the retinal prosthesis. This retinal prosthesis has a 3D-stacked structure, improving area efficiency and realizing high resolution, functionality, and sensitivity. This study fabricated a 3D-stacked retinal prosthesis chip and evaluated the electrical characteristics.
