CHEMICAL MECHANICAL POLISHING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18201967 titled 'CHEMICAL MECHANICAL POLISHING APPARATUS

Simplified Explanation

The chemical mechanical polishing apparatus described in the abstract includes a unique combination of magnetic materials in the polishing pads to enhance the polishing process.

  • The polishing platen features an electromagnet and is rotatable.
  • The lower polishing pad consists of a first area with a magnetic material and a second area with a non-magnetic material, overlapping the electromagnet.
  • The upper polishing pad contains a second magnetic material and overlaps the first area.
  • The polishing head is responsible for providing a wafer on the upper polishing pad and is also rotatable.
