Electric migraiton, Stress migration Overview Electromigration (EM) - Thin film 이나 wire 형태의 전도체에 높은 전류 밀도가 가해질 때 Mass transport 가 일어나는 현상. 이로 인하여 hillock, bridge, void 와 같은 defect 이 발생. - EM 이 발생하는 대표적인 2가지 mechanism : Electron Wind Force (1) Electron wind force : 전자가 금속 이온에 momentum (충돌) 을 가하여 cathode 에서 anode 로 atom diffuse 발생. cathode 에는 void, anode 에는 hilock, whisker 발생 (2) Grain boundary diffusion : Grain boundary triple points 에서 meta..

Introduction As a result of the continuum assumption, field quantities such as density and velocity which reflect the mechanical or kinematic properties of continuum bodies are expressed mathematically as continuous functions, or at worst as piecewise continuous functions, of the space and time variables. Moreover, the derivatives of such functions, if they enter into the theory at all, will be likewise cont..
