Abstract
Transition metal-containing precursors are disclosed. Also disclosed are methods of synthesizing and using the disclosed precursors to deposit transition metal-containing films on one or more substrates via a vapor deposition process.
Claims20
A transition metal-containing precursor having the formula:
- Formula 1), wherein M is selected from the group consisting of V and Ta and each of R1, R2, R3, R4, and R5 is independently selected from the group consisting of H;
- a C1-C5 linear, branched, or cyclic alkyl group;
- a C1-C5 linear, branched, or cyclic alkylsilyl group;
- a C1-C5 linear, branched, or cyclic alkylamino group;
- and a C1-C5 linear, branched, or cyclic fluoroalkyl group.
A process for the deposition of a transition metal-containing film on a substrate, comprising:
- introducing at least one transition metal-containing precursor into a reactor having at least one substrate disposed therein, the at least one transition metal-containing precursor having the following formula:
- wherein M is selected from the group consisting of V, and Ta and each of R1, R2, R3, R4, and R5 is independently selected from H;
- a C1-C5 linear, branched, or cyclic alkyl group;
- a C1-C5 linear, branched, or cyclic alkylsilyl group;
- a C1-C5 linear, branched, or cyclic alkylamino group;
- and a C1-C5 linear, branched, or cyclic fluoroalkyl group;
- and
- depositing at least part of the at least one transition metal-containing precursor onto the at least one substrate to form the transition metal-containing film using a vapor deposition method.
A transition metal-containing precursor having the formula:
- Formula 1), wherein M is Nb and each of R1, R2, R3, R4, and R5 is independently selected from the group consisting of H;
- a C1-C5 linear, branched, or cyclic alkyl group;
- a C1-C5 linear, branched, or cyclic alkylsilyl group;
- a C1-C5 linear, branched, or cyclic alkylamino group;
- and a C1-C5 linear, branched, or cyclic fluoroalkyl group, provided that R2 and R3 are the same.
A process for the deposition of a transition metal-containing film on a substrate, comprising:
