DIELECTRIC PROTECTION LAYER IN MIDDLE-OF-LINE INTERCONNECT STRUCTURE MANUFACTURING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 17459065 titled 'DIELECTRIC PROTECTION LAYER IN MIDDLE-OF-LINE INTERCONNECT STRUCTURE MANUFACTURING METHOD

Simplified Explanation

The patent application describes a method for manufacturing an integrated chip, specifically focusing on the formation of a transistor structure and the creation of a protective layer and contact opening.

  • The method begins by forming a transistor structure over a substrate, which includes source/drain regions and a gate electrode.
  • A lower inter-level dielectric (ILD) layer is then formed over the source/drain regions and around the gate electrode.
  • A gate capping layer is added over the gate electrode to provide additional protection.
  • A selective etch and deposition process is performed to simultaneously create a dielectric protection layer on the gate capping layer and a contact opening within the lower ILD layer.
  • Finally, a lower source/drain contact is formed within the contact opening.

Potential applications of this technology:

  • Integrated circuit manufacturing
  • Semiconductor industry
  • Electronics manufacturing

Problems solved by this technology:

  • Provides a method for forming a protective layer on a gate electrode while simultaneously creating a contact opening, simplifying the manufacturing process.
  • Ensures the integrity and reliability of the transistor structure by protecting it with a dielectric layer.

Benefits of this technology:

  • Simplifies the manufacturing process by combining multiple steps into a single process.
  • Enhances the reliability and performance of the integrated chip by providing a protective layer for the transistor structure.
  • Improves the efficiency of the manufacturing process by reducing the number of required steps.


Original Abstract Submitted

In some embodiments, the present disclosure relates to a method for manufacturing an integrated chip. The method includes forming a transistor structure over a substrate. The transistor structure comprises a pair of source/drain regions and a gate electrode between the source/drain regions. A lower inter-level dielectric (ILD) layer is formed over the pair of source/drain regions and around the gate electrode. A gate capping layer is formed over the gate electrode. A selective etch and deposition process is performed to form a dielectric protection layer on the gate capping layer while forming a contact opening within the lower ILD layer. A lower source/drain contact is formed within the contact opening.
