Patent ID: 8894723

Claim:
A method for formation of a Li-comprising layer on a substrate by atomic layer deposition comprising the following steps: a) providing a substrate in a reaction chamber wherein said reaction chamber is arranged for gas-to-surface reactions, b) pulsing a lithium precursor through said reaction chamber, c) reacting said lithium precursor with at least one surface of said substrate, d) purging of said reaction chamber d1) by sending a purge gas through said reaction chamber for the purging of the reaction chamber or d2) by evacuating said chamber, and repeating steps b) to d) a desired number of times in order for the formation of a thin film layer of a lithium comprising material upon said at least one surface of said substrate, wherein the lithium precursor is selected from among lithium 2,2,6,6-tetramethylheptane-3,5-dionate, lithium alkoxides, lithium alkyls, cyclic lithium compounds, lithium dicyclohexamide, and bimetallic or multimetallic compounds.
