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,…
Winbond Adopts Qimonda’s Buried Wordline Technology – Metal Gates Come to DRAMs
Before Qimonda’s unfortunate demise last year, they delivered an impressive paper at IEDM 2008 [1] describing a “buried wordline” (BwL) DRAM stack-cell structure. This was a marked change from their earlier technology, as until this point all of their product had been based on planar wordline structure with trench-style storage capacitors sunk into the die substrate. Even when we compare BwL-stack with conventional stack DRAM structures, there’s a major shift,…
Where Have All the New Apps Gone?
Increasingly, we are hearing about consolidation in the semiconductor industry. Bill McClean of IC Insights has perhaps pointed this out most clearly, noting that the top 10 capacity leaders held about 60% of the total 2009 worldwide IC capacity, and the top 15% held a 71% share. Looking at only 300mm capacity, the consolidation is even more obvious: the top 10 leaders held an imposing 84% share with the top…
Moore’s Law: Will Lack of R&D Funding Kill It?
In the January issue of Solid State Technology, I wrote about life after the "reset" button and how the lack of R&D funding could well bring an end to Moore’s Law. That very issue was one of the key "take aways" from last week’s ISS. What I heard from a variety of speakers is this: A massive restructuring is underway that will leave only a handful of companies producing devices…
Acro Energy Prez Defines PV User Demands
Acro Energy Technologies Corp., a leading U.S. solar integrator, announced yesterday that it has signed a Stock Purchase Agreement with Energy Efficiency Solar, Inc., a California corporation headquartered in Pomona, Calif. ("EE Solar") and BillKorthof, the sole shareholder of EE Solar. EE Solar is a full-service solar energy company that has been installing residential and commercial solar systems in Los Angeles, Orange, and San Bernardino Counties since 1989. EE Solar…
