摘要:
A method is provided for forming a metal-containing film on a substrate by a sequential gas exposure process in a batch type processing system. A metal-containing film can be formed on a substrate by providing a substrate in a process chamber of a batch type processing system, heating the substrate, sequentially flowing a pulse of a metal-containing precursor gas and a pulse of a reactant gas in the process chamber, and repeating the flowing processes until a metal-containing film with desired film properties is formed on the substrate. The method can form a metal-oxide film, for example HfO2 and ZrO2, a metal-oxynitride film, for example HfxOzNw, and HfxOzNw, a metal-silicate film, for example HfxSiyOz and ZrxSiyOz, and a nitrogen-containing metal-silicate film, for example HfxSiyOzNw and ZrxSiyOzNw. A processing tool containing a batch type processing system for forming a metal-containing film by a sequential gas exposure process is provided.

摘要:
An in situ method for forming a HfO2 high-k dielectric layer in a batch wafer processing system. The method comprises first loading a plurality of wafers into a process chamber, and then pre-treating the plurality of wafers in the process chamber with a first oxidizer. After pre-treating the wafers, and without removing the wafers from the process chamber, the method then comprises depositing HfO2 on the plurality of wafers by atomic layer deposition, which comprises a plurality of deposition cycles, each cycle comprising alternating exposure of the plurality of wafers in the process chamber to a second oxidizer and a hafnium precursor. The hafnium precursor is selected from hafnium tert-butoxide (HTB) or hafnium tetra-diethylamide (TDEAH).
