Abstract
A method for ALD coating of a substrate with a layer containing Ti, Si, N, wherein a reaction gas and then a flushing gas are introduced into a process chamber holding the substrate in a plurality of successive steps, each in one or more cycles, wherein TiN is deposited in a first step with a reaction gas containing Ti and a reaction gas containing N, TiSi is deposited in a second step with a reaction gas containing Ti and a reaction gas containing Si, and in a third step following the second step, TiSiN is deposited with a reaction gas containing Ti, with a reaction gas containing N and with a reaction gas containing Si.
