摘要:
An etching method of the present invention includes a first and a second process. In the first process, pattern widths of a pre-patterned mask layer are increased by depositing plasma reaction products on sidewalls of the mask layer. In the second process, a layer to be etched is etched by using the mask layer as a mask having increased the pattern widths. Therefore, mask layers having different pattern densities exist in the same wafer and pattern widths of mask layers patterned through a photolithography process are uneven according to pattern densities, each pattern width of the mask layers can be made uniform. Accordingly, the pattern widths of the layer can be made uniform over an entire wafer.

A method and system of etching a metal nitride, such as titanium nitride, is described. The etching process comprises introducing a process composition having a halogen containing gas, such as Cl2, HBr, or BCl3, and a hydrocarbon gas having the chemical formula CxHy, where x and y are equal to unity or greater.

摘要:
A substrate processing apparatus carrying out processing on a substrate, which enables attachment of particles to a surface of a substrate to be prevented. A substrate processing apparatus comprises a housing chamber in which the substrate is housed, and a stage that is disposed in the housing chamber and on which the substrate is mounted. The stage having in an upper portion thereof an electrostatic chuck comprising an insulating member having an electrode plate therein, and the electrode plate having a DC power source connected thereto. The DC power source applies a negative voltage to the electrode plate when the substrate is to be attracted by the electrostatic chuck.
