The Week in Review: Dec. 6, 2013

Friday, December 6th, 2013

Worldwide sales of semiconductors reached $27.06 billion for the month of October 2013, a 7.2 percent increase from the same month last year when sales were $25.24 billion, according to preliminary results by Gartner, Inc. The top 25 semiconductor vendors’ combined revenue increased 6.2 percent, a significantly better performance than the rest of the market, whose revenue growth was 2.9 percent. This was, in part, due to the concentration of memory vendors, which saw significant growth in the top ranking.

Soitec, a manufacturer semiconductor materials for the electronics and energy industries, this week announced it has reached high-volume manufacturing of its new Enhanced Signal Integrity (eSI) substrates. Soitec’s eSI products, based on Smart Cut technology, are the first “trap-rich” type of material in full production. These substrates, on which devices are manufactured, have a significant impact on the final devices’ performance. Soitec’s eSI substrates are designed by introducing an innovative material (a trap-rich layer) between the high-resistivity handle wafer and the buried oxide. This layer limits the parasitic surface conduction present in standard high-resistivity silicon-on-insulator (HR-SOI) substrates, boosting the performance of RF devices. Because this layer is built into the substrate, it reduces the number of process steps and relaxes design rules, leading to a lower cost process and possibly a smaller die area per function.

SEMI projects that worldwide sales of new semiconductor manufacturing equipment will contract 13.3 percent to $32.0 billion in 2013, according to the SEMI Year-end Forecast, released this week at the annual SEMICON Japan exposition.  In 2014, all regions except Rest of World are expected to have strong positive growth, resulting in a global increase of 23.2 percent in sales. 2015 sales are expected to continue to grow — increasing 2.4 percent with Japan, Europe, Korea, China, and Rest of World regions registering positive growth.

Micron Technology, Inc. announced that the company has named Rajan Rajgopal, vice president of Quality. Rajgopal will be responsible for overseeing all aspects of Micron’s quality systems including manufacturing, customer program management and product ramps. He brings more than 25 years of experience to Micron and most recently served as the vice president of Global Quality and Customer Enablement for GLOBALFOUNDRIES in Singapore.

SEMI’s World Fab Forecast report, published in November, predicts that fab equipment spending will decline about -9 percent (to US$32.5 billion) in 2013 (including new, used and in-house manufactured equipment).  Setting aside the used 300mm equipment GlobalFoundries acquired from Promos at the beginning of 2013 (NT$20-30 billion), fab equipment spending sinks further, to -11 percent in 2013.  The previous World Fab Forecast in August predicted an annual decline of just -1 percent (-3 percent without the used Promos 300mm equipment).

Worldwide sales of semiconductors reached $27.06 billion for the month of October 2013, a 7.2 percent increase from the same month last year when sales were $25.24 billion, and 0.8 percent higher than last month’s total, according to The Semiconductor Industry Association (SIA). “With eight straight months of growth and a new monthly sales record in October, the global semiconductor industry is on track to exceed $300 billion in annual sales for the first time ever in 2013,” said Brian Toohey, president and CEO, Semiconductor Industry Association. “The industry is projected to maintain solid growth for the remainder of 2013 and into 2014, led largely by the Americas, which has remained well ahead of last year’s pace. Congress and the Administration can help maintain and strengthen growth by resolving fiscal uncertainty and investing in scientific research.”

Advances in Post-Tape Out Resource Management

Monday, November 25th, 2013

By Mark Simmons, CalCM Product Manager, Mentor Graphics, Corp.

Foundries, both pure-play and independent device manufacturers (IDM), rigorously compete for market share. One factor that helps them get and keep business is turnaround time (TAT). As technology nodes advance, achieving targeted production runtimes in the post-tapeout flow gets ever more challenging. TAT is important to the fab’s customers, who are keenly interested in meeting their aggressive time-to-market schedules, and also to the fab because time means resources and money. Although a need for better control of and (in most cases) improved reduction of TAT has always been a challenge, the need for a TAT automated controlling mechanism in the post-tapeout flow has been continually neglected because simply adding more hardware has sufficed up until recently. In addition to adding compute hardware, companies also use these three strategies to achieve faster turnaround time (TAT):

  • Fine tuning OPC recipes
  • Improving input hierarchical handling of incoming designs
  • Upgrading to newer software versions to take advantage of new functionalities and performance benefits

Historically, distributed processing tasks require an upfront allocation of hardware and software resources. These resources must be pre-determined prior to starting the run, and are held for the duration of the run. As the jobs run, you can see periods when not all of the allocated resources are being used. Those resources could be used by other jobs, but there is no way to gain access to them. Clearly, this situation can be improved by better utilizing what you have through dynamic resource allocation. In fact, recently published results using a cluster manager software (Guo et. al. 2013, SPIE 8684) demonstrated just over a 30% aggregate TAT improvement for a large set of jobs in conjunction with a greater than 90% average utilization across all hardware resources.

Here’s how it works. The cluster manager software governs the hardware and software resources for all jobs running on a remote compute cluster (Figure 1). It automatically provides idle resources to jobs that can use them, and revokes resources from jobs when they are not being used. In conjunction with focusing on a single job’s performance, it also improves the efficiency of resources at the cluster level, considering all cluster tasks together as a whole. The software optimizes the distribution of resources to all of the jobs running simultaneously on the cluster. In doing so, the result is both an overall aggregate runtime performance improvement and an effective maximization of utilization across the cluster resources.

This type of dynamic resource management does the important work of reducing TAT, which is imperative in the competitive foundry industry. It achieves dynamic resource re-distribution by automatically allocating available CPUs to jobs that can use more capacity and by removing CPUs from jobs that are already at or over capacity. Resource allocation is determined by job need, level of importance, resource partitioning, and available resources. But, this system also gives the foundry monitoring information and system- and job-level controls. These features are vital to making decisions regarding the post-tapeout flow and then providing a means to react to them in ways that make the process more efficient and improve the bottom line.

Forecast for 2013

Saturday, December 1st, 2012

By Pete Singer

Nobody can predict the future, of course, but 2013 is shaping up to be a good year for the semiconductor industry and its suppliers. According to SEMI, total fab spending for equipment needed to ramp fabs, upgrade technology nodes, and expand or change wafer size could increase 16.7 percent in 2013 to reach a new record high of $42.7 billion. The estimate includes new equipment, used equipment, or in-house equipment but excludes test assembly and packaging equipment (which, if included, would bring the number up to about $50 billion). The market for semiconductor manufacturing materials, which was $48.6 billion this year, is expected to grow 4% to more than $50 billion in $2013.

There’s been some hand-wringing in 2012 about continued consolidation and the number of companies that will be moving to 450mm: most pundits guess that only 5-7 companies will be able to make the move. However, that’s a limited view of the industry, since there are hundreds of facilities around the world cranking out chips, LEDs, optoelectronics, power devices, MEMS and other components. The latest edition of the SEMI World Fab Forecast lists over 1,150 facilities (including 300 opto/LED facilities), with 76 facilities starting production in 2012 and in the near future.

There’s sure to be much talk in 2013 about technology requirements at the leading edge, including the 450mm transition, progress in EUV, 3D integration and FinFET optimization. Sustainability will be key, with an emphasis on reducing power consumption, which means lower leakage currents and reduced Vdd.

The demand for semiconductors will never be higher, particularly as the middle class rise on dominance in places such as Brazil, Russia, India and China. First on the wish list it seems, after shelter, food and clothing, is a smart phone.
After a trip to imec in Leuven, Belgium, I’m particularly bullish on opportunities in healthcare, which range from body area sensor networks to amazingly advanced labs-on-a-chip that can screen 20 million blood cells per second to find a single tumor cell in 5 billion blood cells. It is these kinds of applications that could lead to a new revolution in how electronics are designed and manufactured.
