Abstract

In an embodiment, a system includes: a base with a bore hole, wherein the base is configured to secure a wafer at a first position on the base; a pin extending through the bore hole; a focus ring horizontally surrounding the wafer at the first position and extending upwardly from the base, wherein the wafer is configured to be moved vertically between the first position and a second position above the focus ring via the pin; and a slit valve above the focus ring, wherein the wafer is configured to be moved horizontally between the second position and the slit valve via a robotic arm.
