There are many effects that contribute to semiconductor aging. Thermal stress and diffusion, as you and the child comment suggested, are definitely part of it. There is also electromigration, which can cause the interconnect to fail. In advanced nodes there are effects related to the magnitude of the electric field and the various material interfaceds, such as hot-carrier injection (HCI). Here's an article which gives explanation of a few aging effects: https://spectrum.ieee.org/semiconductors/processors/transist... |
