Abstract

A system and a method for feeding a solid into a solid deposition system is described. Solid contained in a hopper is directed into a vibratory bowl. The frequency of the vibrations of the vibratory bowl can be modulated by a feedback system. The solid can then be entrained in a carrier gas which can flow to a distributor for deposition on a substrate.
