Abstract:
1. A semiconductor device manufacturing apparatus, comprising: a load lock chamber; a first treatment chamber and a second treatment chamber which carry out plasma treatment; a transfer chamber connected with the load lock chamber and the first and the second treatment chambers via gate valves; means for transferring a treated material; and a control means for controlling the transferring means so that the treated material is transferred within vacuum environment via the transfer chamber by opening and closing the gate valve among the load lock chamber, the first and the second treatment chambers, and for controlling gas pressure in the first and the second treatment chambers, wherein the apparatus performs an in-situ PVD method which forms a high dielectric film on a treated material by reacting a metal film and a silicon-containing film, and forms a metal electrode film on the high dielectric film without exposing the treated material to the atmosphere, and wherein: the first treatment chamber includes means for depositing the metal film on a silicon oxide film or a silicon oxynitride film having a thickness from 1 nm to 2 nm or less to form the treated material by a sputtering method; the second treatment chamber includes means for heat-treating the metal film of the treated material to form the high dielectric film; the control means transfers, within vacuum environment, the treated material with the metal film deposited thereon in the first treatment chamber to the second treatment chamber by the transferring means via the transfer chamber; the control means controls oxygen partial pressure in the second treatment chamber into 1×10 the control means introduces oxygen to the second treatment chamber after the treated material is transferred to the second treatment chamber during heat-treating the metal film on the treated material; and the control means controls annealing treatment after depositing a metal electrode material on the high dielectric film so as to be carried out at the temperature of 700° C. or more.
