Abstrakt: Ruthenium films have been deposited via a pulsed CVD process using tris(2,2,6,6-tetramethyl-3,5-heptanedionato) ruthenium (i.e., Ru(thd)3) , oxygen, and hydrogen at 280 and 300{degree sign}C. Film resistivity near theoretical values (16 uO-cm at 3 nm) was achieved with repeatability. Films were smooth and continuous down to 2 nm; a low density of pinholes could be observed on films with 1 nm thickness. Adhesive tape tests indicated good adhesion. Carbon content is low.
