Overcoming RC In Memory Scaling

In a memory device, Ohmic contacts (semiconductor-to-metal interfaces) connect the active region and the metal wiring. To achieve rapid and maximal charge transmission across the Ohmic contact, a low-resistivity material is used. Low-resistivity Co silicide has been adopted as the industry standard for this purpose; its effectiveness relies on the deposition of a sufficiently thick layer to for... » read more

RC Delay: Bottleneck To Scaling

R = resistance — the difficulty an electrical current has in passing through a conducting material. C = capacitance — the degree to which an insulating material holds a charge. RC delay = the delay in signal speed through the circuit wiring as a result of these two effects. RC delay is important because it can become a significant obstacle to continued downward scaling of logic and... » read more
