Patent ID: 7799135

Claim:
An atomic layer deposition apparatus, comprising: a plurality of reaction space surfaces defining a reaction space; a substrate support structure housed within the reaction space; a plurality of feed lines connecting the reaction space to sources of vapor phase reactants suitable for a vapor deposition process, wherein at least some of the reactant space surfaces comprise a surface modification deactivating the at least some surfaces against the vapor deposition process, the surface modification comprising a protective self-assembled monolayer (SAM) layer that comprises adsorbed organic reactant molecules, wherein one end of each reactant molecule is adsorbed onto a hydrophilic surface whereas the other end of each reactant molecule is hydrophobic; and a control system programmed to operate said reaction space at temperatures in excess of approximately 200° C., the control system configured to provide alternated and repeated pulses of the vapor phase reactants to the reaction space in accordance with an atomic layer deposition sequence.
