20140299059VAPOR DELIVERY SYSTEM - Vapor delivery systems for chemical depositions are shown in which the vapor delivery systems are capable of simultaneous buffering and fast response. The vapor delivery systems achieved the functionality using a two-volume system. The first volume mainly functions as a buffer to stabilize perturbations in vapor flow upstream. The second volume is smaller than the first volume so that the second volume responds to a change in vapor flow quickly. Optionally, a fixed flow restrictor is connected to the second volume and the fixed flow restrictor buffers downstream fluctuations.10-09-2014
