Abstract:
1. A chamber component configured to be coupled to a processing chamber, comprising: a chamber element comprising a first surface on a supply side of said chamber element and a second surface on a process side of said chamber element, said process side opposing said supply side, wherein said chamber element comprises an opening having an interior surface that is formed through said chamber element from said first surface to said second surface, and wherein said interior surface is a conical surface or a right circular cylindrical surface; an insert member insertable within said opening such that, when inserted within said opening, said insert member extends through and occupies said opening from said first surface of said chamber element to said second surface of said chamber element, said insert member comprising a groove formed in an outer surface of said insert member that extends along a helical path from an inlet at said supply side of said chamber element to an outlet at said process side of said chamber element; and a second insert member insertable within a second opening having a second interior surface that is formed through said insert member from a top surface of said insert member to a bottom surface of said insert member, wherein, when inserted within said second opening, said second insert member extends through and occupies said second opening from said top surface to said bottom surface, said second insert member comprising a second groove formed in a second outer surface of said second insert member that extends along a second helical path from a second inlet at said supply side of said chamber element to a second outlet at said process side of said chamber element, wherein the portion of said outer surface remaining after forming said groove in said outer surface contacts and mates with said interior surface of said opening in said chamber element when said insert member is inserted within said opening of said chamber element, wherein, when said insert member is inserted within said opening of said chamber element, a helical conduit extending through said chamber element from said supply side to said process side is formed by said interior surface of said opening and said groove in said outer surface of said insert element, said helical conduit configured to receive a process fluid at said inlet and to distribute said process fluid at said outlet within a processing system for treating a substrate, wherein the portion of said second outer surface remaining after forming said second groove in said second outer surface contacts and mates with said second interior surface of said second opening in said insert member when said second insert member is inserted within said second opening of said insert member, and wherein, when said second insert member is inserted within said second opening of said insert member, a second helical conduit extending through said insert member from said supply side to said process side is formed by said second interior surface of said second opening and said second groove in said second outer surface of said second insert element, said second helical conduit configured to receive said process fluid at said second inlet and to distribute said process fluid at said second outlet within said processing system for treating said substrate.
