A molecule rotating on the surface of a crystal can function as a tunnel-gate of a transistor, as shown by researchers from the Paul-Drude-Institut für Festkörperelektronik (PDI) and the Freie Universität Berlin (FUB), Germany, the NTT Basic Research Laboratories (NTT-BRL),…
Ferromagnetic Room Temperature Switching
Bismuth-ferrite could make spin-valves that use 1/10th the power of STT A research team led by folks at Cornel University (along with University of California, Berkeley; Tsinghua University; and Swiss Federal Institute of Technology in Zurich) have discovered how to…
Nakamura Co-Wins Nobel for Blue LEDs
The Nobel Prize in Physics 2014 was awarded jointly to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura “for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources”. In the late 1980s red and…
Chasing IC Yield when Every Atom Counts
Increasing fab costs coming for inspection and metrology At SEMICON West this year in Thursday morning’s Yield Breakfast sponsored by Entegris, top executives from Qualcomm, GlobalFoundries, and Applied Materials discussed the challenges to achieving profitable fab yield for atomic-scale devices…
Moore’s Law is Dead – (Part 4) Why?
We forgot Moore merely meant that IC performance would always improve (Part 4 of 4) IC marketing must convince customers to design ICs into electronic products. In 1965, when Gordon Moore first told the world that IC component counts would…
Moore’s Law is Dead – (Part 3) Where?
…we reach the atomic limits of device scaling. At ~4nm pitch we run out of room “at the bottom,” after patterning costs explode at 45nm pitch. Lead bongo player of physics Richard Feynman famously said, “There’s plenty of room at…
