WAFER CHUCK, METHOD FOR PRODUCING THE SAME, AND EXPOSURE APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18504007 titled 'WAFER CHUCK, METHOD FOR PRODUCING THE SAME, AND EXPOSURE APPARATUS

Simplified Explanation

The wafer chuck described in the patent application is made of a ceramic containing silicon carbide, with an oxidation-treated layer on the base and a diamond-like carbon (DLC) film on the outermost surface.

  • The base of the wafer chuck is made of a ceramic material that includes silicon carbide.
  • An oxidation-treated layer is applied to the base to enhance its durability and resistance to wear.
  • A film made of diamond-like carbon (DLC) is formed on the outermost surface of the base to further improve its performance and longevity.

Potential Applications

  • Semiconductor manufacturing
  • Wafer processing
  • Thin film deposition

Problems Solved

  • Improved durability and wear resistance of wafer chucks
  • Enhanced performance in semiconductor manufacturing processes

Benefits

  • Extended lifespan of wafer chucks
  • Increased efficiency in wafer processing
  • Reduced maintenance and replacement costs
