Abstract
Provided are methods of depositing silicon-containing films utilizing certain precursors at temperatures of 400° C. or higher. Certain methods comprise exposing a substrate surface to a silicon precursor and another precursor to achieve various films. Examples of silicon-containing films which can be deposited include SiN, SiC, SiO2, SiCN, etc.
Claims6
A method of depositing a film comprising silicon, the method comprising:
- a. contacting a substrate surface with a first precursor having a structure represented by (I):
- wherein R1-6 are each independently H or C1-4 alkyl;
- and
- b. contacting the substrate surface with at least one oxygen, nitrogen and/or carbon precursor to deposit a film comprising silicon,
- wherein the substrate surface has a temperature of about 400° C. or greater.
