A few days after IBM and Micron publicized their hybrid memory cube, IBM gave their TSV paper at IEDM on the Monday afternoon (paper 7.1). Entitled "3D Copper TSV Integration, Testing and Reliability," they described a node-agnostic through-silicon via (TSV) technology which takes a via-middle configuration, making contact to the upper metal (fat-wire) layers in the device structure. By "node-agnostic" they mean that they proved the concept in devices fabbed…

Intel clarifies 32nm NMOS stress mechanism at IEDM 2011
I was browsing through the advance program for the upcoming IEDM conference when, almost at the end, I came across paper number 34.4, "Modeling of NMOS Performance Gains from Edge Dislocation Stress," by Weber et al. of Intel. According to the abstract: "Simulations show stress from edge dislocations introduced by solid phase epitaxial regrowth increases as gate pitch is scaled, reaching over 1GPa. This makes edge dislocations attractive, as stress…

GLOBALFOUNDRIES Takes a Different Approach to HKMG in AMD’s Llano CPU/GPU
After much anticipation, and with quite a few design wins, AMD’s Llano CPU/GPU chip arrived on the scene a couple of months ago. Fabricated by GlobalFoundries (more easily known as GloFo) in their 32nm SHP process, it was the first foundry-based gate-first HKMG product to come on the market. As a processor, it garnered pretty favorable reviews, but of course we were keen to get it into the lab and…
