Arrhenius Model

13 Test, Reliability, Yield & Failure Analysis

Notation AF = exp[(E_a/k)(1/T_use - 1/T_stress)]

Definition

A temperature-acceleration model for thermally activated processes in which reaction or failure rate changes exponentially with inverse absolute temperature and an activation-energy parameter.

Application

Used in semiconductor reliability and process engineering to estimate acceleration factors, extrapolate lifetime from elevated-temperature tests, and model diffusion, migration or reaction-driven mechanisms.
