摘要:
It is an object of the present invention to effectively and efficiently inhibit the influence of an eliminated gas from a built-up film deposited in a reaction chamber and reduce an incubation time to improve flatness of a thin film. A manufacturing method of a semiconductor device includes a preprocess step and a film-forming step. In the preprocess step, an RPH (Remote Plasma Hydrogenation) process of supplying a hydrogen radical onto a substrate (202), thereafter, an RPN (Remote Plasma Nitridation) process of supplying a nitrogen radical onto the substrate (203), and thereafter, an RPO (Remote Plasma Oxidation) process of supplying an oxygen radical onto the substrate (204) are performed during a substrate temperature increase for raising a substrate temperature up to a film-forming temperature. In the film-forming step, after the substrate temperature is raised up to the film-forming temperature, a film-forming process is performed by a thermal CVD method by supplying a source gas onto the substrate (205), and thereafter, the RPO process is performed (206). In this film-forming step, the film-forming source supply onto the substrate and the RPO process are preferably repeated a plurality of times.
摘要:
A semiconductor device manufacturing method by which a process chamber can be self-cleaned, while keeping a temperature in the process chamber low or a semiconductor device manufacturing method by which a high-k film adhering in the process chamber can be effectively removed. The method is provided with a pre-coat process, a film forming process and a cleaning process. Activated F* or Cl* by remote plasma passes through a high-k film (31), reacts to a pre-coat film (30) composed of SiO2 or Si. Since the pre-coat film (30) peels in pieces, the high-k film over the pre-coat film can be removed together.

A method for manufacturing a semiconductor device can efficiently form on a substrate an amorphous thin film containing small amounts of impurities without needs for a rapid annealing treatment and a frequent cleaning process. A method for manufacturing a semiconductor device comprises a film-forming step and a film-modifying step. In the film-forming step, a film formation gas from a film formation raw material supply unit 9 is supplied into a reaction chamber 1 through a shower head 6 to form an amorphous thin film including a hafnium oxide film (HfO2 film) on a substrate 4 which is rotating. In the film-modifying step, a radical generated in a reactant activation unit 11 is supplied through the same shower head 6 as used for supplying the film formation gas, so as to remove a specific element which is an impurity in the film formed in the film-forming step. By a controller 25, the film-forming step and the film-modifying step are subsequently repeated two or more times in the same reaction chamber 1 so as to form a semiconductor device.

To obtain a conductive metal film having superior step coverage, adhesiveness, and high productivity. A conductive metal film or metal oxidized film suitable as a capacitor electrode is formed on a substrate by performing an excited-gas supplying step after a source gas supplying step. In the source gas supplying step, gas obtained by vaporizing an organic source is supplied to the substrate, and the gas thus supplied is allowed to be adsorbed on the substrate. In the excited-gas supplying step, oxygen or nitrogen containing gas excited by plasma is supplied to the substrate to decompose the source adsorbed on the substrate, thus forming a film. An initial film-forming stop is a step of forming the film by repeating the source gas supplying step and the excited-gas supplying step once or multiple times. A desired thickness can be obtained by one step of the initial film-forming step. However, thereafter, in addition to the initial film-forming step, the film-forming step may be two steps by performing the main film-forming step of simultaneously supplying the gas obtained by vaporizing the organic source and oxygen containing gas or nitrogen containing gas not excited by plasma by using a thermal CVD method.
