Source/Drain Metal Contact and Formation Thereof - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240096961 titled 'Source/Drain Metal Contact and Formation Thereof

Simplified Explanation

The abstract describes a contact stack for a semiconductor device that includes a source/drain feature, a silicide layer wrapping around the source/drain feature, a seed metal layer in direct contact with the silicide layer, and a conductor in contact with the seed metal layer. Importantly, the contact stack does not include a metal nitride layer in direct contact with the silicide layer.

  • Source/drain feature included in the contact stack
  • Silicide layer wraps around the source/drain feature
  • Seed metal layer in direct contact with the silicide layer
  • Conductor in contact with the seed metal layer
  • Excludes a metal nitride layer in direct contact with the silicide layer

Potential Applications

The technology described in the patent application could be applied in the manufacturing of advanced semiconductor devices, such as microprocessors, memory chips, and other integrated circuits.

Problems Solved

This innovation helps to improve the performance and reliability of semiconductor devices by providing a more efficient and reliable contact stack structure.

Benefits

The benefits of this technology include enhanced electrical conductivity, improved thermal stability, and reduced resistance in the contact stack of semiconductor devices.

Potential Commercial Applications

The technology could find commercial applications in the semiconductor industry for the production of high-performance electronic devices.

Possible Prior Art

One possible prior art could be the use of metal nitride layers in contact stacks of semiconductor devices to improve conductivity and reliability. However, the exclusion of a metal nitride layer in direct contact with the silicide layer distinguishes this innovation from existing technologies.

Unanswered Questions

How does the absence of a metal nitride layer impact the overall performance of the semiconductor device?

The article does not provide specific details on how the absence of a metal nitride layer affects the performance of the semiconductor device.

Are there any potential drawbacks or limitations to this contact stack design?

The article does not address any potential drawbacks or limitations that may arise from the specific configuration of the contact stack described.


Original Abstract Submitted
