An thermal ink jet printhead is fabricated with resistors of doped diamond. A diamond substrate is masked in the pattern of the resistors and bombarded with boron ions with high energy to embed the boron with only a negligible amount on the surface. If a protective layer is applied, the same mask is used. The process is simple and low cost, and the resulting substrate is hard, insulating, and chemically inert.
