SEMICONDUCTOR DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17865497 titled 'SEMICONDUCTOR DEVICE
Simplified Explanation
The patent application describes a semiconductor device that includes bit line structures, a contact plug structure, and a capacitor. The contact plug structure consists of three sequentially stacked contact plugs, with the third plug filling an upper recess on the surface of the second plug and protruding above it. The upper surface of the third plug is higher than the top surface of the bit line structures.
- The semiconductor device includes bit line structures, a contact plug structure, and a capacitor.
- The contact plug structure consists of three sequentially stacked contact plugs.
- The second contact plug has an upper recess on its surface.
- The third contact plug fills the upper recess and protrudes above it.
- The upper surface of the third contact plug is higher than the top surface of the bit line structures.
Potential Applications
- This semiconductor device can be used in various electronic devices such as computers, smartphones, and tablets.
- It can be utilized in memory modules, processors, and other integrated circuits.
Problems Solved
- The stacked contact plug structure allows for efficient electrical connection between the bit line structures and the capacitor.
- The protrusion of the third contact plug above the upper recess ensures a reliable and stable connection.
- The higher surface of the third contact plug provides improved performance and functionality of the semiconductor device.
Benefits
- The design of the contact plug structure enhances the overall performance and reliability of the semiconductor device.

Original Abstract Submitted
A semiconductor device may include bit line structures on a substrate, a contact plug structure on the substrate between the bit line structures, and a capacitor electrically connected to the contact plug structure. The contact plug structure may include a first contact plug, a second contact plug, and a third contact plug sequentially stacked. An upper surface of the second contact plug includes an upper recess. The third contact plug may fill the upper recess, and may protrude above the upper recess. An upper surface of the third contact plug may be higher than a top surface of the bit line structures.
