Abstract:
1. A method for treating a plurality of discrete semiconductor substrates, comprising: providing a reaction chamber comprising a pair of opposing sidewalls, the opposing sidewalls being a first sidewall and second sidewall, the reaction chamber comprising an inlet extending through the first sidewall and an outlet extending through the second sidewall, the first sidewall having a surface area that is reduced by at least about 50% due to the inlet, the second sidewall having a surface area that is reduced by at least about 50% due to the outlet; placing the plurality of discrete semiconductor substrates in the reaction chamber; flowing a first reactive material into the chamber through the inlet to simultaneously expose the plurality of discrete semiconductor substrates to the first reactive material within the chamber to form a first mass across at least some exposed surfaces of the plurality of discrete semiconductor substrates; exhausting the first reactive material through the outlet to remove the first reactive material from the reaction chamber; and after the removing, flowing a second reactive material into the chamber through the inlet to simultaneously expose the plurality of discrete semiconductor substrates to the second reactive material and convert the first mass to a second mass, the second mass comprising one or more of Ta, Ti, W, Al, Hf, SiO and Zr; wherein the listed composition of SiO is shown in terms of the elements contained therein rather than in terms of a stoichiometric relationship of the elements.
