Abstract
The present invention relates to a method for fabricating a semiconductor device for stimulation and/or data recording of biological material to a such semiconductor device. The method comprises providing a semiconductor substrate comprising a first insulating layer; providing a patterned conductive layer on top of the first insulating layer; depositing and patterning a second insulating layer atop the patterned conductive layer; growing carbon nano-sheets atop the second insulating layer; and defining carbon nano-sheet electrode areas on the second insulating layer by etching away the carbon nano-sheets outside of the carbon nano-sheet electrode areas.
