INTEGRATED PHOTORESIST REMOVAL AND LASER ANNEALING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17749038 titled 'INTEGRATED PHOTORESIST REMOVAL AND LASER ANNEALING

Simplified Explanation

The patent application describes a method for forming a semiconductor device.

  • The method involves removing a light-sensitive material from a workpiece using polarized electromagnetic radiation.
  • The workpiece is then annealed, or heated, using electromagnetic radiation polarized in a different direction than the one used for removing the light-sensitive material.
  • In some cases, the electromagnetic radiation used for annealing is not polarized.
  • The method also ensures that the removed light-sensitive material is exhausted from the chamber where the removal process takes place, preventing it from depositing on chamber surfaces.


Original Abstract Submitted

A method of forming a semiconductor device includes removing a light-sensitive material from a workpiece utilizing polarized electromagnetic radiation and annealing features on the workpiece utilizing electromagnetic radiation polarized in a different direction than the polarized electromagnetic radiation utilized to remove the light-sensitive material. In some embodiments, the electromagnetic radiation used to anneal the features on the workpiece is not polarized. In some described embodiments, light-sensitive material removed from the workpiece is exhausted from the chamber in which the light-sensitive removal process is carried out before it can deposit on surfaces of the chamber.
