Patent ID: 8770143

Claim:
A semiconductor processing chamber, comprising: a substrate support configured to support a substrate; and a moveable process head disposed within the semiconductor processing chamber; wherein the moveable process head comprises an inner wall and a moveable assembly disposed within the inner wall, wherein the moveable process head is moveably attached to an inner surface of the inner wall through a seal enabling slideable translation of the movable process head in a direction perpendicular to the substrate; wherein a shield is spaced apart from and surrounds at least a lower portion of the inner wall, wherein a plurality of non-overlapping site isolated process regions can be defined on the substrate by the position of the inner wall relative to the substrate, and each site isolated process region is defined as the area on the substrate within the inner wall, wherein the shield is operable as a barrier to isolate deposition from the movable process head to a single site isolated region; wherein the moveable process head is operable to perform a dry process on the site isolated process region, wherein an enclosed processing region is defined as the volume between the inner wall, the movable process head, and the substrate, and wherein the enclosed processing region can be evacuated through a circumferential gap below the inner wall contemporaneously with the performing of the dry process.
