MOL
Middle of Line
MOL is the process domain that forms contacts and local interconnections between device terminals and upper interconnects.
Other learning contexts (1)
In context
A contact is an electrical connection to a device. As contacts become smaller, reducing electrical resistance at the interface becomes important alongside accurately opening and filling the holes.
Example
The exact boundary between FEOL and MOL can vary by technology and organization. Understand them through their function of connecting device terminals to interconnects rather than simply memorizing the names.
Key distinction
Even if a device operates well, an incomplete contact makes it difficult to deliver current to the circuit.
