According to the method of forming a titanium nitride film, first, an inside of a reaction pipe accommodating a semiconductor wafer is heated up to 200° C. to 350° C. by using a temperature increasing heater. Then, the titanium nitride film is formed on the semiconductor wafer by supplying a film forming gas including a titanium raw material into the reaction pipe. Methylcyclopentadienyl tris(dimethylamino)titanium that does not include a chlorine atom and includes titanium is used as the titanium raw material.
摘要:
Atomic layer deposition using a precursor having both nitrogen and silicon components is described. The deposition precursor contains molecules which supply both nitrogen and silicon to a growing film of silicon nitride. Silicon-nitrogen bonds may be present in the precursor molecule, but hydrogen and/or halogens may also be present. The growth substrate may be terminated in a variety of ways and exposure to the deposition precursor displaces species from the outer layer of the growth substrate, replacing them with an atomic-scale silicon-and-nitrogen-containing layer. The silicon-and-nitrogen-containing layer grows until one complete layer is produced and then stops (self-limiting growth kinetics). Subsequent exposure to a plasma excited gas modifies the chemical termination of the surface so the growth step may be repeated. The presence of both silicon and nitrogen in the deposition precursor molecule increases the deposition per cycle thereby reducing the number of precursor exposures to grow a film of the same thickness.
