Abstract:
A film formation method and a film formation apparatus for semiconductor processing are provided to improve characteristics of a device by controlling accurately elements of a silicon nitride layer. A film forming apparatus(2) includes a processing receptacle(4), a supporting member, a heater(86), an exhaust system(GE), a first processing gas supply system(30), a second processing gas supply system(28), an excitation unit, and a control unit(60). The processing receptacle has a processing area for receiving a processing target substrate. The supporting member supports the processing target substrate in the processing area. The heater heats the processing substrate within the processing area. The exhaust system exhausts the processing area. The first processing gas supply system supplies a first processing gas including a silane-based gas to the processing area. The second processing gas supply system supplies a second processing gas including a nitrous gas to the processing area. The excitation unit performs an excitation operation while the second processing gas supply system supplies the second processing gas to the processing area. The controller controls operations of the film forming apparatus.
Abstract:
A film forming apparatus is provided to suppress contamination of particles in forming a silicon nitride layer or a silicon oxynitride layer by forcibly exhausting the byproducts separated from the inner surface of a reaction chamber. A layer selected from a group composed of a silicon nitride layer or a silicon oxynitride layer is formed on a substrate to be processed in a reaction chamber of a film forming apparatus. The substrate to be processed is unloaded from the reaction chamber. While the inner surface of the reaction chamber is heated to a post-process temperature, post-process gas for nitridization is supplied to the inside of the reaction chamber to perform nitridization of a byproduct layer attached to the inner surface of the reaction chamber. The inner surface of the reaction chamber is cooled rapidly from the post-process temperature to crack the byproduct layer after the nitridization by using thermal stress while the byproduct layer is separated from the inner surface of the reaction chamber. The inside of the reaction chamber is forcibly exhausted so that the byproduct layer separated from the inner surface is loaded into an air current to be exhausted from the reaction chamber. The post-process gas includes gas selected from a group composed of ammonia and nitride oxide.
