Claim Text:
1. An apparatus for vapor deposition, comprising: a reaction space configured to receive a substrate; a first plurality of precursor source vessels in fluid communication with the reaction space, wherein a first vessel of the first plurality of precursor source vessels contains a first source chemical and is configured to vaporize the first source chemical, and a second vessel of the first plurality of precursor source vessels contains the same first source chemical and is configured to vaporize the first source chemical wherein the first source chemical comprises at least one of a liquid and solid; and a controller configured to cause delivery of pulses of gas containing the first source chemical from at least two of the first plurality of precursor source vessels to the reaction space during a deposition on a common substrate, wherein the controller is configured to supply the pulses of gas containing the first source chemical from the at least two of the first plurality of precursor source vessels during the deposition on the common substrate, wherein the pulses each includes at least some reactant from the first vessel of the first plurality of vessels, and from the second vessel of the first plurality of vessels, wherein the controller is configured to cause delivery of said pulses for pulse durations in a range between about 0.1 and 10 seconds.
