Abstract:
A composition comprising dihydropyrazinyl anions that can be coordinated as 6 electron ligands to a broad range of different metals to yield volatile metal complexes for ALD and CVD depositions are described herein. Also described herein are undeprotonated dihydropyrazines that can coordinate to metals as stabilizing neutral ligands. In one embodiment, the composition is used for the direct liquid injection delivery of the metal dihydropyrazinyl complex precursor to the chamber of an ALD or CVD chamber for the deposition of metal-containing thin films such as, for example, ruthenium or cobalt metal films.

Claim (Index 7):
A method for forming a metal film on a substrate wherein the film comprises a thickness, the method comprising:\n a. introducing a metal dihydopyrazinyl complex comprising at least one selected from a Formula 3D, 3E compound or combinations thereof; b. chemisorbing the metal dihydopyrazinyl complex onto the substrate; c. purging away the a metal dihydopyrazinyl complex using a purge gas; d. providing a reducing agent to the metal dihydopyrazinyl complex onto the heated substrate to react with the sorbed metal dihydopyrazinyl complex; and e. optionally purging away any unreacted reducing agent.
