Qualcomm Shies Away From High-k At 28nm


By David Lammers Qualcomm CDMA Technologies said it will not use a high-k/metal gate (HKMG) process for most of the chips it makes at the 28 nm node, sticking with a poly/SiON gate stack. The company described the rationale behind the strategy, which because of Qualcomm’s size will have a major impact on the foundry business, at the 2010 International Electron Devices Meeting (IEDM) held in ... » read more

Power Optimization Below 28nm


By Pallab Chatterjee Process scaling has normally been performed on a lithographic basis, but as processes dip below 32nm there are optimization options beyond the lithographic and area reduction. The Common Platform Group and GlobalFoundries have added the tradeoffs of power and performance optimization in addition to area in their 28nm flows. TSMC uses a five-way optimization that also h... » read more
