SEMICONDUCTOR DEVICES HAVING CONTACT PLUGS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18368939 titled 'SEMICONDUCTOR DEVICES HAVING CONTACT PLUGS
Simplified Explanation
The abstract describes a semiconductor device that includes various components such as a substrate, active regions, contacts, wiring layers, and contact plugs.
- The device has a cell area and a peripheral circuit area, each with its own active region.
- A direct contact is made to the first active region in the cell area.
- A bit line structure is placed on the direct contact.
- A capacitor structure is electrically connected to the first active region.
- A gate structure is placed on the second active region in the peripheral circuit area.
- Lower wiring layers are located adjacent to the gate structure and connected to the second active region.
- Upper wiring layers are placed on top of the lower wiring layers.
- A wiring insulating layer is positioned between the lower and upper wiring layers.
- Upper contact plugs are connected to either the lower or upper wiring layers and extend through the wiring insulating layer.
Potential applications of this technology:
- Semiconductor devices used in various electronic devices such as smartphones, computers, and tablets.
- Memory devices, such as dynamic random-access memory (DRAM) or flash memory.
Problems solved by this technology:
