SEAL RING STRUCTURE FOR SEMICONDUCTOR DEVICE AND THE METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 17708894 titled 'SEAL RING STRUCTURE FOR SEMICONDUCTOR DEVICE AND THE METHOD THEREOF

Simplified Explanation

The abstract describes a semiconductor structure that consists of a circuit region and a seal ring region. The circuit region is located on a substrate and is surrounded by the seal ring region. The circuit region includes first and second fins, with n-type epitaxial structures over the first fins and p-type epitaxial structures over the second fins. The seal ring region consists of fin rings that encircle the circuit region and epitaxial rings that are parallel to the fin rings. All of the epitaxial rings in the seal ring region are p-type epitaxial rings.

  • The semiconductor structure includes a circuit region and a seal ring region.
  • The circuit region has first and second fins with different types of epitaxial structures.
  • The seal ring region consists of fin rings and epitaxial rings.
  • All of the epitaxial rings in the seal ring region are p-type epitaxial rings.

Potential Applications

  • This semiconductor structure can be used in various electronic devices such as integrated circuits and microprocessors.
  • It can be applied in the manufacturing of high-performance transistors and other semiconductor components.

Problems Solved

  • The seal ring region provides protection and isolation for the circuit region, preventing interference from external factors.
  • The different types of epitaxial structures in the circuit region allow for the creation of specific electrical properties, enhancing the performance of the semiconductor structure.

Benefits

  • The seal ring region ensures the integrity and reliability of the circuit region by providing a barrier against external influences.
  • The use of different types of epitaxial structures allows for precise control over the electrical characteristics of the semiconductor structure, leading to improved performance and functionality.


Original Abstract Submitted

A semiconductor structure according to the present disclosure includes a circuit region disposed over a substrate and a seal ring region disposed over the substrate and completely surrounding the circuit region. The circuit region includes first fins, second fins, n-type epitaxial structures over the first fins, and p-type epitaxial structures over the second fins. The seal ring region includes fin rings extending completely around the circuit region, epitaxial rings disposed over and extending parallel to the fin rings. All of the epitaxial rings over all of the fin rings in the seal ring region are p-type epitaxial rings.
