Abstract:
A method for producing a tantalum nitride layer on a substrate, comprising; directly injecting by liquid flow controller/vaporizer/injector a liquid mixture of (R.sup.1 R.sup.2 N).sub.3 Ta(.dbd.NR.sup.3) and (R.sup.4 R.sup.5 N).sub.3 Ta(.eta..sup.2 -R.sup.6 N.dbd.C (R.sup.7)(R.sup.8)) into a dispersing zone and delivering a resulting dispersed mixture in a reactor containing said substrate at elevated temperature and reacting said mixture with a source of nitrogen added to said mixture in a volumetric ratio of 3:1 to 8:1 of ammonia, to produce said tantalum nitride layer on said substrate, where R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7 and R.sup.8 are individually aryl, C.sub.1-6 alkyl, or hydrogen.
