We introduce the coupling of three-dimensional transient electro-thermal interconnect simulations with intrinsic thermo-mechanical stress solutions. In order to study the development of local thermal stresses we use a finite element simulator for the investigation of complex layered interconnect structures at different operating conditions. The obtained local stress, temperature distribution, t...

Using TCAD tools, many reliability issues can be studied quantitatively. Examples are hot carrier degradation of interfaces, threshold voltage shifts during NBTI stress, radiation effects and so...

State of the arts on guided-wave optical switch arrays are reviewed. In this paper, electro-optic Ti:LiNbO3 devices are mainly described in comparison with crosspoint switch element structures and switch array architectures. Packaging technologies and stability problems are discussed for practical system applications. Recent development on other materials such as semiconductor waveguides, therm...

A thermally fixed photorefractive Bragg grating is written in a single-mode Ti:Fe:Er:LiNbO3 channel waveguide and used to develop a distributed feedback-distributed Bragg reflector coupled cavity laser with a second broadband dielectric cavity mirror. The optically pumped (lambda(p) = 1480 nm, P = 130 mW) laser emits in single-frequency operation as much as 8 mW at lambda = 1557.2 nm with a slo...

Even under normal operating conditions, power devices are subject to temperature changes that generate high level of stress repeatedly causes mechanical breakdown. In this context thermomechanical simulations are necessary to predict life time and guarantee a longer lifespan. This paper aims to modeling electro-thermo-mechanical behavior of a vertical power transistor for predicting the influen...

The recycling of sodium borohydride poses a huge challenge to the drive towards hydrogen economy. Currently, mechano-chemical, thermo-chemical and electrochemical are only reported methods metaborate into borohydride. Much attention has been devoted mechano-chemical reduction, but little focus methods. This review describes behaviour (BH4−) (BO2−) anions in alkaline solutions. BH4− is stabilize...

In this chapter, we apply the variational principle/weighted residual method based on nonlocal operator for derivation of forms elasticity, thin plate, gradient electro–magneto-elasticity and phase field fracture method. The governing equations are expressed as integral support dual-support. first example shows that elasticity has same form dual-horizon non-ordinary state-based peridynamics. is...
