Patent ID: 7713377

Claim:
Apparatus for plasma treating a substrate comprising: a chamber; a gas flow system configured to cause a flow of at least one gas within said chamber and to remove said gas from said chamber; a plasma generator for causing the at least one gas within the chamber to form a plasma, said plasma generator comprising an induction coupled plasma source having an RF coil encircling said chamber, thereby generating at least one species said plasma being generated in a plasma generation region extending between a wall of said chamber which is proximal to said RF coil, and a first width which is distal from said RF coil; and a detachable guide for directing the gas flow containing the species towards said substrate to be treated, said guide defining a path through which said at least one gas and said at least one species flow from said plasma generating region to said substrate; said guide having an entrance and an exit, said entrance having a second width and being disposed proximal to said plasma generating region, said exit having a third width and being disposed proximal to said substrate to be treated; said second width being greater than said first width, and said third width is less than said first width, said guide being configured such that at least one gas is directed toward said substrate to be treated.
