Method for Gapfill - A simplified explanation of the abstract

This abstract first appeared for US patent application 18083075 titled 'Method for Gapfill

Simplified Explanation

The method described in the abstract involves depositing sacrificial Si and metal layers in an opening of a feature on a substrate, replacing the Si layer with the metal layer, and filling the gap with a metal gapfill material.

  • Depositing sacrificial Si and metal layers in an opening and on a field of a substrate
  • Replacing at least a portion of the sacrificial Si layer with the metal layer
  • Depositing a metal gapfill material in the opening directly over the metal layer to completely fill the opening

Potential Applications

This technology could be applied in semiconductor manufacturing, specifically in the fabrication of integrated circuits and other electronic devices.

Problems Solved

This method helps to fill small gaps and trenches in semiconductor devices, improving the overall performance and reliability of the devices.

Benefits

- Improved gap filling in semiconductor devices - Enhanced device performance and reliability - Cost-effective manufacturing process

Potential Commercial Applications

Original Abstract Submitted

A method of gap fill may include depositing a sacrificial Si layer in an opening of a feature and on a field of a substrate. In addition, the method may include depositing a metal layer in the opening and on the field, where at least a portion of the sacrificial Si layer is replaced with the metal layer. The method may also include depositing a metal gapfill material in the opening and on the field directly over the metal layer, where the metal gapfill material completely fills the opening.
