Patent ID: 7118783

Claim:
A method of processing a micro-device workpiece in a reaction chamber, comprising: placing a volume of a volatilizable reaction precursor in an interior of a vessel having a sidewall and a rotation axis disposed at an angle with respect to vertical to define a headspace in the vessel interior above the volume of the reaction precursor; determining the angle with respect to vertical based on a volatility of the reaction precursor; rotating the vessel about the rotation axis in a manner that deposits a quantity of the reaction precursor on an interior surface of the sidewall exposed to the headspace and volatilizes the reaction precursor as the vessel rotates; delivering a carrier gas to the headspace; delivering a reaction gas from the headspace to the reaction chamber, the reaction gas comprising the carrier gas and the volatilized precursor; and depositing a reaction product on a surface of the micro-device workpiece, the reaction product being derived, at least in part, from the volatilized precursor.
