Abstract:
A method of forming nickel layers in a deposition chamber on a plurality of substrates, the deposition chamber having at least one heating element the method comprising:heating the deposition chamber with the at least one heating element prior to introduction of a first substrate; introducing the first substrate to the deposition chamber while heating the deposition chamber with the at least one heating element; depositing a layer of nickel on the first substrate while heating the deposition chamber with the at least one heating element; removing the first substrate from the deposition chamber while heating the deposition chamber with the at least one heating element; introducing a second substrate to the deposition chamber while heating the deposition chamber with the at least one heating element; and depositing a layer of nickel on the second substrate while heating the deposition chamber with the at least one heating element, wherein the chamber is heated with the at least one heating element continuously between the removal of the first substrate and the introduction of the second substrate.
