Fast Qualification of Solder Reliability in Solid-state Lighting System

Solid-state lighting (SSL), which is based 0n semiconductor Lighting Emitting Diode (LED), is the most promising and reliable energy saving solution for future lighting applications. Since a bare LED die can hardly survive without a package, one of the most import function of the LED package is to facilitate the electrical connection and heat...

Liquid-Si Technology for High-Speed Circuits on Flexible Substrates

Recently, flexible, wearable and disposable electronics have attracted a lot of attention. Printing enables low-cost fabrication of circuits on flexible substrates. Printed organic and metal oxide thin-film transistors (TFTs) have been researched intensively due to the ease of solution-processing. But their carrier mobility and reliability are...

Bioparticle Separation in Microfluidic Devices for in-Line Application

There was an explosive growth in the bioprocess industry market during the last decade. The tight control of these processes is often very critical in order to optimize the process efficiency or even achieve the right product. Capillary electrophoresis (CE) system is a good option for process monitoring and controlling, since it has already been...

Molecular simulation strategy for mechanical modeling of amorphous/porous low-dielectric constant materials

We propose an amorphous/porous molecular connection network generation algorithm for simulating the material stiffness of a low-k material (SiOC:H). Based on a given concentration of the basic building blocks, this algorithm will generate an approximate and large amorphous network. The molecular topology is obtained by distributing these blocks...

SiGe growth on patterned Si(001) substrates: Surface evolution and evidence of modified island coarsening

The morphological evolution of both pits and SiGe islands on patterned Si(001) substrates is investigated. With increasing Si buffer layer thickness the patterned holes transform into multifaceted pits before evolving into inverted truncated pyramids. SiGe island formation and evolution are studied by systematically varying the Ge coverage and...

Numerical simulation on the mechanical characteristics of double-stranded DNA under axial stretching and lateral unzipping

The mechanical characteristics of the long-chain double-stranded DNA (dsDNA) molecule under the axial stretching and lateral unzipping are studied by the clustered atomistic-continuum method (CACM). The CACM consisted of the clustered atom method (CAM) and the atomistic-continuum method (ACM). The CAM treats the specific atomic group as the...
