Substrate Bombardment with Ions having Targeted Mass using Pulsed Bias Phase Control - A simplified explanation of the abstract
This abstract first appeared for US patent application 17945408 titled 'Substrate Bombardment with Ions having Targeted Mass using Pulsed Bias Phase Control
Simplified Explanation
The method described in the abstract involves plasma processing by generating plasma with specific ion densities and delivering an energetic ion flux to a substrate at a precise timing.
- Plasma is generated by coupling a source power pulse to a plasma processing chamber.
- The plasma contains first ions with a certain mass and second ions with a greater mass.

Original Abstract Submitted
A method of plasma processing includes generating plasma by coupling a source power pulse to a plasma processing chamber containing a substrate holder configured to support a substrate. The plasma includes first ions having a first mass and second ions having a second mass greater than the first mass. The ion density ratio of the second ions to the first ions is a first ratio. The method further includes delivering an energetic ion flux of second ions to the substrate by applying a delayed bias power pulse to the substrate holder after a delay between the source power pulse and the delayed bias power pulse. The delay is chosen based on the diffusion time constants of the first ions and the second ions so that the ion density ratio of the second ions to the first ions is a second ratio that is greater than the first ratio.
