At the IBM/GLOBALFOUNDRIES/Samsung Common Platform Technology Forum on Tuesday, Gary Patton of IBM announced that the Platform would be moving to a gate-last high-k, metal-gate (HKMG) technology at the 20-nm node. At the 45- and 32-nm nodes there has been a dichotomy between gate-last as embodied by Intel, TSMC, and UMC, and gate-first, promoted by the Common Platform and others such as Panasonic. (Though, to be realistic, Intel’s is the…

Common Platform Goes Gate-Last – at Last!
At the IBM/GLOBALFOUNDRIES/Samsung Common Platform Technology Forum on Tuesday, Gary Patton of IBM announced that the Platform would be moving to a gate-last high-k, metal-gate (HKMG) technology at the 20-nm node. At the 45- and 32-nm nodes there has been a dichotomy between gate-last as embodied by Intel, TSMC, and UMC, and gate-first, promoted by the Common Platform and others such as Panasonic.

IEDM 2010 Retrospective – Part 1
The International Electron Devices Meeting started its 56th session last week on Sunday in San Francisco. This year the program appears to more academic than in previous years, and this was confirmed by the conference chair in his opening address – only 145 submissions out of a total of 555, an all-time low as a percentage. Attendance was guesstimated at ~1500, again lower than earlier years on the west coast.…
IEDM Next Week!
Next Sunday the great and the good of the electron device world will be gathering in San Francisco for the 2010 IEEE International Electron Devices Meeting. To quote the conference web front page, “IEDM has been the world’s main forum for reporting breakthroughs in technology, design, manufacturing, physics and the modeling of semiconductors and other electronic devices.” From my perspective at Chipworks, focused on chips that have made it to…
TI Ships 40-µm Fine Pitch Copper Pillar Flip Chip Packages
The week before Semicon West, Texas Instruments and Amkor released a joint announcement that they were shipping parts in fine pitch copper pillar packages. Mark Lapedus at EETimes picked the story up and added the detail that the latest OMAP processors were going out in this format. By coincidence, Chipworks had just finished analysing TI’s Sitara AM3715, a 45-nm applications processor with a 1-GHz ARM Cortex-A8 core and a POWERVR…
Non-Intel HKMG Coming Soon? And 45LP Makes the Mainstream in Mobiles
The last few weeks have seen some announcements that finally seem to show that HKMG (high-k, metal-gate) processes other than Intel are coming into the real world. First, on September 7, Samsung showed off an engineering sample of their 32-nm Saratoga chip at their Mobile Solutions forum. A week later on the 15th, Panasonic declared that in October they would be shipping 32-nm HKMG chips for use in Blu-ray disc…
Samsung’s Eight-Stack Flash Shows up in Apple’s iPhone 4
Back in 2005 Samsung made an announcement that they would be shipping eight die stacked in the same package. At the time it seemed remarkable, but we didn’t see it any time soon after that, so it got lost in the noise of other package developments and the increasing TSV (through-silicon vias) hype. Last year we commented, in the now defunct Semiconductor International, on a 16GB Sandisk Micro-SD flash card…
The Bankability of PV Tech: The New Key to Success
A decidedly non-technical term was in vogue this week at the very technical 25th European Photovoltaic Solar Energy Conference (EUPVSEC). The term “bankability” was often used to describe the likelihood of success of a given technology. In these days of scarce capital, the only projects that will be funded are those that banks and insurers have deemed to be fund-worthy (outside of China anyway). “Banks demand extensive performance and reliability…
3 Facts from EUPVSEC
The one and only driving factor in the photovoltaics industry is cost per Watt. This is primarily a function of efficiency – how much of the sun’s power is converted to electricity — and the cost of manufacturing and installation. The ultimate goal of course is to achieve grid parity, where the cost of producing power with PV is the same or better than that achieved by traditional means (coal,…
10 million solar roofs in U.S. bill passes
The Ten Million Solar Roofs Act of 2010 (S. 3460) was was passed by the Energy and Natural Resources Committee by a vote of 13 to 10 on July 21, 2010. It was introduced by Sen. Bernie Sanders, a member of the Senate energy and environment committees and chairman of the green jobs subcommittee. The bill sets a goal, to be met through this and other incentive and R&D programs,…
