University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

The current state of the art of embedded motion sensing is based around micro-electromechanical systems (MEMS) devices. These miracles of microfabrication use tiny silicon structures, configured to ...

Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical ...

Measuring high aspect ratio and composite micro-trenches without damage is critical for advanced microfabrication, yet conventional coherence scanning interferometry often suffers from a low signal-to ...

Dynamic interferometry allows precise optical measurements to be made on the factory floor. Steve Martinek explains the principle and technology behind the technique. The high-precision interferometry ...

Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision ...

Electronic and computer processors with a higher speed need smaller features for integrated circuits (IC), which also need smoother and smaller substrate surfaces. Chemical mechanical polishing (CMP) ...

One of the biggest challenges for nanoscale fabrication is how to measure devices on such a minute scale. As the semiconductor industry demands ever smaller devices, the need for reliable, robust ...

Fuzziness may rule the quantum realm, but it can be manipulated to our advantage. When two black holes spiral inward and collide, they shake the very fabric of space, producing ripples in space-time ...
