Cu interconnects with Ru diffusion barriers
Extensive characterization of physical vapor-deposited ruthenium and RuxNy films was carried out to evaluate their performance as a copper diffusion barrier.
Creating shaped piezo silicon micropumps using MEMS-based manufacturing
Microelectromechanical systems (MEMS) technology is driving progress in the manufacturing of new “inkjetting” products called shaped piezo silicon micropumps.
A 90nm wafer-level technique for thin-film stress monitoring
Coherent gradient sensing (CGS) is an emerging thin-film stress metrology technique that provides a method to map wafer-level stress on both blanket and patterned films.
Using multiple transducers at sub-65nm for single-wafer megasonics-based cleaning
Wafer cleaning has traditionally relied on the combination of strong chemistries and high-power megasonic energy to achieve cleaning efficiencies >90%.
The big picture for nanotech
Few technologies in recent memory have generated more confusion than nanotechnology.
The challenges of adjusting scaling control knobs
In 1965, Gordon Moore first observed an exponential growth in the number of transistors per IC and devised a law that threw down a gauntlet and, through intense competition, has enabled amazing gains ...
Nanometer deposition processes create new challenges for cryopumps
Every time cryogenic pumps are pushed to lower pressures in semiconductor manufacturing, new and often unexpected phenomena occur.
A major shakeup in reliability testing
If there is one grand truth in the semiconductor industry, it is this: Simple device scaling to achieve performance gains is dead.
