One-On-One: Dave Hemker


Dave Hemker, CTO at [getentity id="22820" comment="Lam Research"], sat down with Semiconductor Engineering to look at some of the key issues on the process and manufacturing side, and some of the key developments that will reshape the semiconductor industry in the future. What follows are excerpts of that conversation. SE: One of the big discussion topics these days is [getkc id="208" commen... » read more

Bulk CMOS Vs. FD-SOI


The leading edge of the chip market increasingly is divided over whether to move to finFETs or whether to stay at 28nm using different materials and potentially even advanced packaging. Decisions about which approach to take frequently boil down to performance, power, form factor, cost, and the maturity of the individual technologies. All of those can vary by market, by vendor and by process... » read more

No More Straight Lines


Shrinking features on a chip is no longer the only way forward, and in an increasing number of designs and markets, it is no longer the best way forward. Power and performance are generally better dealt with using different architectures and microarchitectures, and all of those provide the potential to reduce silicon area (cost). Cramming more transistors on a die and working around leakage... » read more

FinFET Scaling Reaches Thermal Limit


In 1974, Robert H. Dennard was working as an IBM researcher. He introduced the idea that MOSFETs would continue to work as voltage-controlled switches in conjunction with shrinking features, providing doping levels, the chip's geometry, and voltages are scaled along with those size reductions. This became known as Dennard's Law even though, just like Moore's Law, it was anything but a law. T... » read more

Virtualization Revisited


Virtual instruction set computing (VISC) is getting a second look as power and performance improvements begin to slow and [getkc id="74" comment="Moore's Law"] is supplanted by [getkc id="279" comment="Koomey's Law"]. While the current crop of [getkc id="185" kc_name="finFETs"] will likely be extended for at least one more process node, there is some debate about what comes next, whether tha... » read more

Rethinking Processor Architectures


The semiconductor industry's obsession with clock speeds, cores and how many transistors fit on a piece of silicon may be nearing an end for real this time. The [getentity id="22048" comment="IEEE"] said it will develop the International Roadmap for Devices and Systems (IRDS), effectively setting the industry agenda for future silicon benchmarking and adding metrics that are relevant to specifi... » read more

Automating System Design


Change is underway in the chip design world, creating opportunities and challenges that reach far beyond questions about whether Moore’s Law is slowing or stopping. Never before in the history of semiconductors has design been so complex and sophisticated, and never has it touched so many lives in so many interesting ways. This is all happening as a result of the chip’s enabling role in ... » read more

Foundries Expand Their Scope


By Ed Sperling & Mark LaPedus Major foundries are stepping up their offerings across a wide swath of technology nodes, specialty processes and advanced packaging—a recognition that end markets are fragmenting and that the path forward includes a mix of new and established processes. As the smart phone market flattens, there is no single "next big thing" to drive volume at the most ... » read more

Rightsizing Challenges Grow


Rightsizing chip architectures is getting much more complicated. There are more options to choose from, more potential bottlenecks, and many more choices about what process to use at what process node and for which markets and price points. Rightsizing is a way of targeting chips to specific application needs, supplying sufficient performance while minimizing power and cost. It has been a to... » read more

GPU-Based Computing In Photomask Manufacturing


Graphical-processing unit (GPU)-accelerated computing has reached maturity for professional, scientific computing applications. One example of this is the recent GPU-accelerated thermal application for semiconductor photomask manufacturing, which is used in 24/7 manufacturing environments. GPU-accelerated computing won’t be a universal panacea for the semiconductor industry’s “need for sp... » read more
