Tantalum and niobium reagents useful in chemical vapor deposition processes, and process for depositing coatings using the same

摘要

Niobium and tantalum compounds suitable for use as chemical vapor deposition source reagents, and a process for depositing niobium- or tantalum-containing coatings using the compounds. The compounds have formulaM(OR1)x(R2-C(GH)-C-C(G)-R3)ywherein M is tantalum or niobium; G is oxygen or sulfur; and R1, R2, and R3 are independently selected hydrocarbyl, fluoroalkyl or alkoxy groups.
