Diverging and converging patterns forming on the surface of solidifying liquid metals resemble plotlines in a complex historical novel, in a new international study. The cyclic patterns observed are ...

It's critical that the surface of silicon wafers be as flat as possible so that as each metal layer is patterned, you minimize the risk of moving in and out of the focal plane of the imaging system.

As silicon photonics manufacturing gains momentum with additional foundry and 300mm offerings, process variation issues are coming to light. Variability in silicon processing affects the waveguide ...
