Patent ID: 7794787

Claim:
A method of depositing material over a semiconductor substrate, comprising: forming a first mixture that comprises one or more metal-containing precursors dispersed in a supercritical fluid; and performing at least one iteration comprising the following steps in the following order: flowing the first mixture into a chamber containing the semiconductor substrate to form a monolayer over a surface of the semiconductor substrate, the monolayer containing one or more metals from the one or more metal-containing precursors, the first mixture being flowed into the reaction chamber under conditions such that the supercritical fluid transforms from a supercritical state to a non-supercritical state within the chamber to thereby reduce solubility of the one or more metal-containing precursors within the mixture and cause release of the one or more metal-containing precursors from the mixture as a pulse of the one or more metal-containing precursors within the chamber; purging the chamber; flowing one or more oxygen-containing precursors into the chamber, oxygen from the one or more oxygen-containing precursors reacting with the one or more metals of the monolayer; and purging the chamber.
