Abstract
A system is provided for the manufacture of carbon based electrical components including, an ultraviolet light source; a substrate receiving unit whereby a substrate bearing a first layer of carbon based semiconductor is received and disposed beneath the ultraviolet light source; a mask disposed between the ultraviolet light source and the carbon based semiconductor layer; a doping agent precursor source; and environmental chemical controls, configured such that light from the ultraviolet light source irradiates a doping agent precursor and the first carbon layer.
