Understanding Edacities in Semiconductor Manufacturing: Mitigating Degradation and Extending Lifespan

Edacities is a term used in the context of semiconductor manufacturing and design. It stands for "Electrical Degradation Accelerated by Contacts and Interconnects."

In semiconductor devices, contacts and interconnects are the parts of the chip where the electrical connections are made between different components. These connections can cause degradation of the semiconductor material over time due to electromigration, electrochemical reactions, and other mechanisms. This degradation can lead to changes in the electrical properties of the device, such as increased resistance or reduced current carrying capacity.

Edacities is a phenomenon that refers to the accelerated degradation of the semiconductor material in the vicinity of contacts and interconnects due to the electrical stress and heat generated by the current flowing through them. This can lead to premature failure of the device or reduced lifespan compared to other parts of the chip that are not subjected to such high electrical stress.

To mitigate edacities, semiconductor manufacturers use various techniques such as using low-resistance materials for contacts and interconnects, minimizing the number of contacts and interconnects, and optimizing the design of the chip to reduce electrical stress and heat generation.
