1. A retinal prosthesis, comprising:
a vertically integrated photosensitive junction field-effect-transistor (Photo-JFET) etched from a silicon substrate doped to form a stack of N—P—N or P—N—P layers, forming a silicon mesa pillar and having an outer wall which is coated with a dielectric layer of SiO2, which induces an inversion layer along a vertical direction on the outer wall of the silicon mesa; and
a neural stimulating electrode.
