The manufacturing method includes: providing a semiconductor structure, where the semiconductor structure includes an active region and a gate structure located in the active region, the gate structure at least including a gate electrode, and the active region exposing an upper surface of the gate electrode; forming a surface insulator layer on the upper surface of the gate electrode; forming a patterned interlayer dielectric layer on the semiconductor structure, where the interlayer dielectric layer covers the surface insulator layer, and has a first through hole exposing a portion of the active region; and forming a conductive contact layer passing through the first through hole and contacting with the active region. The present disclosure may reduce a leakage current which is possibly generated between the conductive contact layer and the gate electrode, so as to improve the performance of the device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device having a surface insulating layter and manufacturing method therefor","description":"The present disclosure relates to the technical field of semiconductors, and discloses a semiconductor device and a manufacturing method therefor.
