Patent ID: 6900095

Claim:
A method for forming a hydrogen barrier layer, comprising the steps of: loading a substrate to a deposition chamber; and supplying Al and Ti sources and a reaction gas to the deposition chamber to deposit a complex oxide material including Ti and O 2 to Al on the substrate, wherein the Al source is Alx 3 , where X is any one substrate selected from a group consisting of H, alkyl having about 1 to 10 carbon branches, alkenyl having about 2 to 10 carbon branches, alkoxy having about 1 to 8 carbon branches, aryl having about 6 to 12 carbon branches, β-diketonates, cyclopentadienyl, alkylcyclopentadienyl having about 1 to 8 carbon branches and derivatives of the above listed substrates added with one of halogen elements.
