ANGLED CONTACT WITH A NEGATIVE TAPERED PROFILE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17664671 titled 'ANGLED CONTACT WITH A NEGATIVE TAPERED PROFILE
Simplified Explanation
The patent application describes a microelectronics device with a specific design for the contact and gate regions.
- The device has a contact located above the source/drain region, which is divided into three sections: bottom, middle, and top.
- The sidewalls of these sections are tapered towards the center Y-axis of the contact.
- There is also a gate contact located above the gate region, which also has tapered sidewalls towards the center Y-axis.
- The gate contact is positioned adjacent to the contact.
- The tapering of the sidewalls of the gate contact is the opposite of the tapering of the sidewalls of the contact.
Original Abstract Submitted
A microelectronics device including a gate region located adjacent to a source/drain region. A contact located above the source/drain region, where the contact has a bottom section, a middle section and top section, wherein the sidewalls of the bottom section, the middle section, and the top section of the contact are tapered towards a center Y-axis of the contact. A gate contact located above the gate region, where the gate contact has tapered sidewalls towards a center Y-axis of the gate contact. The gate contact is adjacent to the contact. The tapering of the sidewalls of the gate contact is inverse to the tapering of the sidewalls of the contact.
