The invention provides a light-simulated neural
electrode device based on a golden wire
ball bonding method and a manufacturing method thereof. The method comprises steps: 1, a patterned bottom
polyimide insulation layer is manufactured, and square holes are opened; 2, a middle circuit layer is manufactured; 3; a patterned top
polyimide insulation layer is manufactured, and square holes and round holes are opened at the same positions; 4; a micro LED bare
chip is placed in two
layers of
polyimide square holes, and instantaneous
drying glue is applied to the periphery of the micro LED bare
chip; 5, by adopting the golden wire
ball bonding method, the micro LED bare
chip and a golden circuit layer are connected; 6,
epoxy resin glue is applied for realizing packaging; and 7, a sacrificial layer is corroded, and
electrode release is completed. The
electrode device of the invention mainly aims at providing power for the micro LED bare chip, and light emitting by the LED carries out light
simulation on an
experimental animal with specific
gene transfection; and the process is simple, the LED is arranged flexibly, devices of different forms can be manufactured according to different
simulation areas, and a new tool is provided for implantable
medical device development and
neuroscience research.
