SEMICONDUCTOR DEVICES AND METHODS OF MANUFACTURING THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 17460198 titled 'SEMICONDUCTOR DEVICES AND METHODS OF MANUFACTURING THEREOF

Simplified Explanation

The patent application describes a method for fabricating a semiconductor device. Here are the key points:

  • The method involves forming a substrate and creating a plurality of fins that extend from the substrate. These fins include active fins in an active region and an inactive fin in an inactive region.
  • The active fins are separated by first trench regions, while the inactive fin is separated from its closest active fin by a second trench region. The second trench region is wider than the first trench regions.
  • A dummy fin is formed on the isolation dielectric in the second trench region. This dummy fin is positioned between the active fins and the inactive fin.
  • A dummy gate is then formed over the fins, and a gate isolation structure is placed between the dummy fin and the inactive fin. This structure separates different regions of the dummy gate.

Potential applications of this technology:

  • This method can be used in the fabrication of various semiconductor devices, such as transistors, integrated circuits, and microprocessors.
  • It can be applied in the manufacturing of electronic devices like smartphones, computers, and other consumer electronics.

Problems solved by this technology:

  • The method addresses the challenge of efficiently fabricating semiconductor devices with active and inactive regions.
  • It solves the problem of effectively isolating the inactive fin from the active fins and the dummy gate.

Benefits of this technology:

  • The method allows for the simplified fabrication of semiconductor devices with active and inactive regions.
  • It provides improved isolation between the active and inactive regions, enhancing the performance and reliability of the semiconductor device.
  • The use of dummy fins and gates helps optimize the design and functionality of the device.


Original Abstract Submitted

A method of fabricating a semiconductor device is described. A substrate is provided. A plurality of fins is formed extending from the substrate, the fins including a first group of active fins arranged in an active region, and including an inactive fin having at least a portion in an inactive region, the active fins separated by first trench regions between adjacent of the active regions, the inactive fin separated from its closest active fin by a second trench region, the second trench region having a greater width than that of a trench region of the first trench regions. A dummy fin is formed on the isolation dielectric in the second trench region, the dummy fin disposed between the first group of active fins and the inactive fin. A dummy gate is formed over the fins. The gate isolation structure is disposed between the dummy fin and the inactive fin and separates regions of the dummy gate.
