Drowning In Choices


There are at least half a dozen possible options for 28nm process technologies. There will be even more for the finFET generation. And that’s just the beginning of how complicated things will become over the next few years. There are multiple ways to test, seemingly infinite numbers of IP offerings—even from the same IP providers—and even more packaging options to put them together. Th... » read more

Shootout At 28nm


By Ed Sperling & Mark LaPedus Samsung, Soitec and STMicroelectronics are joining forces on 28nm FD-SOI, creating a showdown with TSMC and others over the best single-patterned processes and materials and raising questions about how quickly companies need to move to the finFET technology generation. The multi-source manufacturing collaboration agreement for fully depleted silicon-on-insulato... » read more

Beyond Moore’s Law


What do you make of all the different reports coming out of Advanced Lithography 2014 — the end of Moore's Law, continued problems with EUV, directed self-assembly assembly makes progress? An equipment insider, whose judgment I value, came back from the meeting and concluded, "We will see the end of Moore’s Law shrinks in 2020. After that, no one knows!” There is no way a $300B+ business ... » read more

Powerful Memories


Memory consumes more of the surface area of a die than any other component. So what changes have happened over the past few years to reduce the power consumption of memories, and where are the big opportunities for saving power? Let's take a closer look. A Growing Concern One of the key drivers for SoCs is the desire to reduce product costs, reduce form factors, reduce power, increase perfo... » read more

Follow The Investments


Where is design heading over the next few years. The best way to tell that is to find out where the development dollars are going, and foundries and tools always precede actual designs. The foundries are starting to spend money—lots of it—on finFETs and 28nm. And while they’re talking about 2.5D and 3D, the money isn’t going there just yet. In fact, there are two different processes ... » read more

Improving Yield Of 2.5D Designs


While progress is being made on the packaging side of 2.5D design, more needs to be resolved when it comes to improving yields. Proponents of 2.5D present compelling benefits. Arif Rahman, a product architect at Altera, noted that the industry trend of silicon convergence is leading to multiple technologies being integrated into single-chip solutions. “2.5D/3D integration has multiple adva... » read more

Time To Revisit 2.5D And 3D


Chipmakers are reaching various and challenging inflection points. In logic, many IC makers face a daunting transition from planar transistors at 20nm to finFETs at 14nm. And on another front, the industry is nearing the memory bandwidth wall. So perhaps it’s time to look at new alternatives. In fact, chipmakers are taking a hard look, or re-examining, one alternative—stacked 2.5D/3D chi... » read more

How Much Will That Chip Cost?


From the most advanced process nodes to the trailing edge of design there is talk about the skyrocketing cost of developing increasingly complex SoCs. At 16/14nm it’s a combination of multi-patterning, multiple power domains and factoring in physical and proximity effects. At older nodes, it’s the shift to more sophisticated versions of the processes and new tools to work within those proce... » read more

Challenges In 3D Resists


3D integration straddles the line between CMOS fabs and packaging and assembly houses. Depending on the structure being fabricated, the most appropriate process might be more “CMOS-like” or more “package-like.” For example, in CMOS fabs lithography means spin-on photoresist, exposed by a high precision stepper. Inherent in this approach is an assumption that the wafer surface is flat... » read more

Litho Is Out Of Sync


EUV’s repeated missed deadlines, and the slow-motion response by the rest of the industry to fill the void with alternatives, is having ripple effects in every facet and corner of the semiconductor industry. It’s making design harder and more expensive, introducing potential errors into the DFM flow, and greatly increasing the amount of time it takes to process wafers. It’s also adding a ... » read more
