SELF-ALIGNED EMBEDDED SOURCE AND DRAIN CONTACTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17851658 titled 'SELF-ALIGNED EMBEDDED SOURCE AND DRAIN CONTACTS

Simplified Explanation

Abstract: An integrated circuit structure has a contact for a source or drain region, where the contact has an upper portion outside the source or drain region and a lower portion extending within the source or drain region. The lower portion of the contact is surrounded by the source or drain region, creating a close adjacency between the contact and the source or drain region.

• The integrated circuit structure includes a contact for a source or drain region.
• The contact has an upper portion outside the source or drain region.
• The contact also has a lower portion that extends within the source or drain region.
• The lower portion of the contact is surrounded by the source or drain region.
• The close adjacency between the contact and the source or drain region is achieved by the source or drain region wrapping around the lower portion of the contact.

Potential Applications:

• This integrated circuit structure can be used in various electronic devices such as smartphones, computers, and IoT devices.
• It can be applied in the manufacturing of microprocessors, memory chips, and other integrated circuits.
• The technology can be utilized in the development of advanced semiconductor devices for high-performance computing, artificial intelligence, and telecommunications.

Problems Solved:

• The integrated circuit structure solves the problem of inefficient contact between the source or drain region and the contact.
• It addresses the issue of limited surface area for contact in small-scale integrated circuits.
• The technology provides a solution for improving the electrical performance and reliability of integrated circuits.

Benefits:

• The close adjacency between the contact and the source or drain region enhances the electrical connectivity and efficiency of the integrated circuit.
• The improved contact design allows for better control of current flow and reduces resistance, leading to enhanced performance.
• The technology enables higher integration density and miniaturization of integrated circuits, leading to more compact and efficient electronic devices.

Original Abstract Submitted

An integrated circuit structure includes a source or drain region, and a contact for the source or drain region. The contact has (i) an upper portion outside the source or drain region and (ii) a lower portion extending within the source or drain region. For example, the source or drain region wraps around the lower portion of the contact, such that an entire perimeter of the lower portion of the contact is adjacent to the source or drain region.
