Abstract: 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.

Abstract: In one embodiment, a semiconductor manufacturing apparatus includes a container to contain wafers, and supporting tables provided in the container so as to be stacked on one another, and each including a supporting face that comes into contact with a wafer to support the wafer. The apparatus further includes supporting columns to join the supporting tables together and provided at positions where the supporting columns are contained inside outer circumferences of the supporting tables. The apparatus further includes a gas feeder to feed a gas to the wafers on the supporting tables, and a gas discharger to discharge the gas fed to the wafers on the supporting tables. Each of the supporting tables includes a first upper face as the supporting face, and a second upper face provided so as to surround the first upper face at a level higher than a level of the first upper face.
