摘要： A method of oxidizing an object to be processed comprises the steps of: providing an object to be processed W having a groove 4 formed on its surface in a processing vessel 22 capable of forming a vacuum therein, oxidizing the surface of the object to be processed in an atmosphere including active oxygen species and active hydroxyl species which are generated by supplying an oxidative gas and a reductive gas into the processing vessel to interact the gases. A temperature in the processing vessel during the oxidizing step is set to be equal to or less than 900° C. Thus, not only corner portions of shoulders of a trench (groove) but also corner portions of a bottom portion of the trench can be rounded to have curved surfaces so as to prevent a generation of facet.

摘要： A thermal processing unit of the present invention includes: a holder that holds a plurality of substrates; a reaction container into which the holder is conveyed; a process-gas supplying mechanism that supplies a process gas into the reaction container; and a heating mechanism that heats the reaction container to conduct a film-forming process to the substrates when the process gas is supplied. Flow-rate-parameter table-data associating number-data of the substrates to be processed by one batch-process with target-data of flow-rate parameter of the process gas is stored in a flow-rate-parameter table-data storing part. A controlling unit obtains target-data of flow-rate parameter of the process gas, depending on an actual number of the substrates to be processed by one batch-process, based on the flow-rate-parameter table-data stored in the flow-rate-parameter table-data storing part, and controls the process-gas supplying mechanism according to the obtained target-data. The target-data of flow-rate parameter are determined in such a manner that a speed of the film-forming process is uniform among a plurality of batch-processes in which the numbers of substrates to be processed are different from each other.

摘要： An oxidation method of oxidizing surfaces of workpieces heated at a predetermined temperature in a vacuum atmosphere in a processing vessel produces active hydroxyl and active oxygen species. The active hydroxyl and active oxygen species oxidize the surfaces of the workpieces in a processing vessel. Both the intrafilm thickness uniformity and the characteristics of the oxide film can be improved, maintaining oxidation rate on a relatively high level.
