Abstract
Preferred embodiments mask select regions of a circuit surface (141) prior to abrading the surface with diamond particles to form nucleation sites (200). The mask (150) is then removed prior to forming a diamond layer (160). Diamond layer (160) grows on the surface except in those regions wherein the mask (150) prevented the formation of nucleation sites (200).
