Abstract:
1. An implant apparatus comprising: a plurality of pixel units arranged over a semiconductor device with a front side and a back side, each pixel unit comprising: wherein the photo sensors, the micro electrodes and the circuitry of the pixel units are embedded within one or more layers of material based on a silicon substrate of the semiconductor device, the layers including a semiconductor layer formed via the front side within the silicon substrate, the photo sensors and the circuitry embedded within the semiconductor layer, the circuitry to drive the micro electrodes to stimulate neuron cells for enabling perception of a vision of the light captured by the photo sensors, wherein thickness of the silicon substrate is sized to allow the photo sensors to capture the light from either the front side or the back side, wherein the thickness of the silicon substrate is sized for a flexibility of the semiconductor device to conform to a shape of a human eyeball and allow the micro electrodes in close proximity to the neuron cells for the stimulation, and wherein the pixel units are configured to capture the light for driving the neuron cells within the close proximity with number of the photo sensors per square millimeter higher than 250.
