Patent ID: 7666752

Claim:
A deposition method for a transition metal containing dielectric comprising: providing a substrate with at least one conductive portion at the surface; successively applying a first pre-cursor comprising a transition metal compound and a second pre-cursor predominantly comprising at least one of water vapour, ammonia and hydrazine on the at least one conductive portion for forming a first layer of a transition metal containing material; and successively applying the first pre-cursor and a third pre-cursor comprising at least one of ozone and oxygen on the first layer for forming a second layer of the transition metal containing material, the second layer directly contacting the first layer, wherein the transition metal is chosen from at least one of the group of hafnium and zirconium for forming a dielectric comprising at least one of the group of hafnium oxide and zirconium oxide, and wherein the first layer is formed comprising a transition metal content of at least 50 atomic percent of the transition metal containing material excluding oxygen.
