Patent ID: 8092600

Claim:
An inductive coupling type plasma apparatus, comprising: a conveying means for conveying a substrate having a predetermined width in a predetermined conveying direction along a predetermined conveying path so as to pass through a predetermined processing linear area elongated in a width direction of said substrate orthogonal to the predetermined conveying direction; electric field forming means for forming an induction electric field by a coil, said electric field forming means being elongated to have a first length in the width direction, opposed to said predetermined processing linear area and arranged in parallel to said predetermined processing linear area in such a way that a longitudinal direction of said electric field forming means is matched with a width direction of said substrate being conveyed; gas introducing means for introducing gas containing at least plasma gas in said predetermined processing linear area to supply the gas on said substrate, said gas introducing means being elongated to have a second length in the width direction and arranged in parallel to said predetermined processing linear area between said predetermined processing linear area and said electric field forming means in such a way that a longitudinal direction of said gas introducing means is matched with the width direction; and separating means for separating a region where said electric field forming means is arranged and a region where said gas introducing means is arranged from each other in an airtight fashion, said separating means having a dielectric window which is elongated to have a third length in the width direction and arranged in parallel to said predetermined processing linear area between said predetermined processing linear area and said electric field forming means in such a way that a longitudinal direction of said dielectric window is matched with the width direction, wherein said substrate is processed with plasma generated from the plasma gas by the induction electric field formed by said electric field forming means while said substrate is conveyed to pass through the predetermined processing linear area, and said electric field forming means is arranged along said dielectric window in parallel to said dielectric window.
