Abstract:
1. A method for forming a dielectric structure comprising: placing a substrate in a chamber for performing one of plasma enhanced chemical vapor deposition and plasma enhanced atomic layer deposition, flowing a vapor including at least one of a Si, Si+C, B, Si+B, Si+B+C, and B+C containing precursor, a N containing precursor, and an inert gas into said chamber, heating said substrate in said chamber in the range from 100° C. to 450°, initiating a plasma in said chamber to form a first component comprising at least one of SiCN, SiCNH, SiN, SiNH, BN, BNH, CBN, CBNH, BSiN, BSiNH, SiCBN and SiCBNH on said substrate, while maintaining said plasma, reducing the flow of said N containing precursor to substantially zero while maintaining said flow of said at least one of a Si, Si+C, B, Si+B, Si+B+C, and B+C containing precursor and said inert gas, and flowing an oxidant gas into said chamber to form a second component adjacent said first component, said second component comprising at least one of SiCOH, p-SiCOH, p-SiCNH, p-BN, p-BNH, p-CBN and p-CBNH.
