Summary: | According to an embodiment, a semiconductor manufacturing apparatus includes a chamber, a process gas nozzle, an inert gas nozzle and a hydrogen radical nozzle. The chamber houses at least one substrate. The process gas nozzle is to release process gas toward the substrate in the chamber. The inert gas nozzle is to release inert gas toward the substrate in the chamber. The hydrogen radical nozzle is disposed in the chamber and is to generate hydrogen radicals by heating raw material gas including hydrogen and to release the generated hydrogen radicals toward the substrate during the release of the inert gas. A metal wire is in the hydrogen radical nozzle, and the metal wire includes a metal catalyst for exciting the generation of the hydrogen radicals. |
