Process for forming deposited film from a group II through group VI metal hydrocarbon compound

Process for forming a deposited film on a substrate in the absence of a plasma atmosphere which comprises:

• (a) generating in an activation space an activated species capable of chemically reacting with a compound for film formation, said activated species being generated from the group consisting of F.sub.2, Cl.sub.2, Br.sub.2, I.sub.2, BrF, ClF, ClF.sub.3, BrF.sub.5, BrF.sub.7, IF.sub.5, ICl, and IBr;
• and
• (b) introducing into a film forming space having said substrate, said activated species and said compound for film formation, said compound for film formation represented by the general formula:
• R.sub.n M.sup.2 m
• wherein R is a hydrocarbon radical, M.sup.2 is an element selected from, the group consisting of Be, Mg, Ca, Sr, Ba, Zn, Cd, Hg, Al, Ga, In, Tl, Si, Ge, Sn, Pb, As, Sb, Bi, S, Se, and Te, n is a positive integer equal to the valence of M.sup.2 and m is a positive integer equal to the valence of R;
• said film forming space being remote from said activation space;
• said activated species initiating a chemical reaction with said compound for film formation sufficient to generate chemical species of said compound for film formation, said chemical species capable of directly forming said deposited film whereby said deposited film is formed on said substrate.
