VACUUM DEPOSITION INTO TRENCHES AND VIAS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240021421 titled 'VACUUM DEPOSITION INTO TRENCHES AND VIAS

Simplified Explanation

The abstract describes a plasma deposition apparatus that utilizes a first plasma source with a closed-loop electrode and magnets to produce a plasma confined in a magnetic field. The magnets are embedded in the closed-loop electrode and generate a magnetic field in the center region of the electrode. This plasma is used to sputter atoms off a sputtering target or a backing plate.

  • The apparatus includes a first plasma source with a closed-loop electrode and magnets.
  • The closed-loop electrode defines a center region and has a central axis passing through it.
  • The magnets are positioned outside the inner surface of the closed-loop electrode.
  • The magnets can be partially embedded in the closed-loop electrode.
  • The magnets generate a magnetic field in the center region of the electrode.
  • The closed-loop electrode and magnets produce a plasma of ions.
  • The plasma is used to sputter atoms off a sputtering target or a backing plate.

Potential Applications:

  • Thin film deposition: The plasma deposition apparatus can be used for depositing thin films on various substrates, such as semiconductors, glass, or metals.
  • Surface modification: The plasma can be used to modify the surface properties of materials, such as improving adhesion or creating specific surface functionalities.
  • Coating production: The apparatus can be utilized for producing coatings with desired properties, such as hardness, corrosion resistance, or optical characteristics.

Problems Solved:

  • Efficient plasma confinement: The use of a magnetic field and closed-loop electrode allows for better confinement of the plasma, enhancing its stability and control.
  • Enhanced sputtering process: The plasma of ions produced by the closed-loop electrode and magnets improves the sputtering process, resulting in more efficient atom removal from the target or backing plate.

Benefits:

  • Improved deposition control: The apparatus provides better control over the deposition process, allowing for precise thickness and composition control of the deposited films.
  • Higher deposition rates: The enhanced sputtering process enables higher deposition rates, reducing the overall processing time.
  • Versatile applications: The plasma deposition apparatus can be used in various industries, including semiconductor manufacturing, optics, and surface engineering.
