SEMICONDUCTOR DEVICE CONTACT STRUCTURES AND METHODS OF FABRICATING THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240096985 titled 'SEMICONDUCTOR DEVICE CONTACT STRUCTURES AND METHODS OF FABRICATING THEREOF
Simplified Explanation
The patent application describes methods and devices involving an air gap adjacent to a contact element extending to a source/drain feature of a device. Some embodiments of the method include depositing a dummy layer, which is subsequently removed to form the air gap. The dummy layer and subsequent air gap may be formed after a SAC dielectric layer such as silicon nitride is formed over an adjacent metal gate structure.
- Air gap adjacent to a contact element
- Dummy layer deposited and subsequently removed to form the air gap
- SAC dielectric layer like silicon nitride used in the process
- Metal gate structure involved in the formation
