Abstract:
1. A semiconductor substrate processing system comprising: a frame; a chamber wall enclosing a chamber, the chamber having a first portion and a second portion; a load-lock chamber connected to the frame and being adjacent to the first portion of the chamber; a robotic stage having a base and a robotic arm, the base being connected to the frame and positioned within the first portion of the chamber, the robotic arm being rotatably connected to the base to transport a semiconductor substrate from the load-lock chamber to the second portion of the chamber into a test position; an x-ray source connected to the frame to emit x rays onto the semiconductor substrate, the x rays causing photoelectrons to be emitted from a material on the semiconductor substrate while in the test position; an analyzer connected to the frame to capture the photoelectrons and determine the kinetic energy of the photoelectrons; and a controller being electrically connected to and to control the robotic stage, the x ray source, and the analyzer.
