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…

IBM Shows Graphene as Epi Template

Last month in Nature Communications (doi:10.1038/ncomms5836) IBM researchers Jeehwan Kim, et al. published “Principle of direct van der Waals epitaxy of single-crystalline films on epitaxial graphene.” They show the ability to grow sheets of graphene on the surface of 100mm-diameter…

Leti integrates everything

Now I know how wafers feel when moving through a fab. Leti in Grenoble, France does so much technology integration that in 2010 it opened a custom-developed people-mover to integrate cleanrooms (“Salles Blanches” in French) it calls a Liaison Blanc-Blanc…

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…

Moore’s Law is Dead – (Part 2) When?

…economics of lithography slow scaling. Moore’s Law had been on life support ever since the industry started needing Double-Patterning (DP) at 1/4-pitch of 193nm optical lithography. EUV lithography shows slow and steady progress in source and resist technologies, and ASML…

Moore’s Law is Dead – (Part 1) What?

…twice the number of components won’t appear on the next IC chip (Part 1 of 4) Gordon Moore always calls it “so-called Moore’s Law” when discussing his eponymous observation about IC scaling trends, and he has always acknowledged that it’s…
