Abstract:
A method for atomic layer deposition (ALD) of a metal silicate thin layer which comprises contacting the vapor of an organometal complex of Formula 1 with a substrate and contacting the substrate with the vapor of an oxidant to increase silicon content in the thin layer:(X)a-b-M(Y-(Si(R)3)m)b wherein M is a trivalent or a tetravalent metal ion; R is C1-4 alkyl; X is halogen or C1-4 alkyl; Y is N; a is 3 and b is an integer ranging from 1 to 3 when M is a trivalent metal ion, or a is 4 and b is an integer ranging from 1 to 4 when M is a tetravalent metal ion; and m is 2.
