The New Mobility Era


By Kathryn Ta Transistors are the fundamental building blocks out of which all modern electronic devices are built. Invented in the early 1950s, transistors are the semiconductor switches that control and amplify electronic signals. As demand has grown over the years for greater performance from these devices, chipmakers have responded by packing wafers with twice as many of the transistors th... » read more

Challenges Mount For Interconnect


By Mark LaPedus There are a plethora of chip-manufacturing challenges for the 20nm node and beyond. When asked what are the top challenges facing leading-edge chip makers today, Gary Patton, vice president of the Semiconductor Research and Development Center at IBM, said it boils down to two major hurdles: lithography and the interconnect. The problems with lithography are well documented.... » read more

The Future Of Manufacturing


Semiconductor Manufacturing & Design's Mark LaPedus talks with Randhir Thakur, general manager of Applied Materials' Silicon Systems Group, about what's changing in the foundries, in the equipment necessary to create ICs, and in the structures and materials used in those ICs.

Options And Hurdles Come Into Focus For 3D Stacking


By Mark LaPedus The initial round of stacked 2.5D and 3D chips based on through-silicon vias (TSVs) has emerged in the market. There are other 2.5D/3D chips in the pipeline, but it’s taking longer than expected to bring these devices into production. There are a range of design, manufacturing, supply chain and cost challenges associated with 2.5D/3D designs. The enormous risk to bring ... » read more

The Hidden Costs Of Directed Self-Assembly


By Mark LaPedus Directed self-assembly (DSA) has been billed by some as a potential paradigm shift in semiconductor manufacturing, but it may not turn out to be quite the panacea its proponents suggest—or at least not yet. There are many questions surrounding DSA, an alternative lithography technology that makes use of block copolymers to enable fine pitches. Key among those questions ar... » read more

The 28nm Foundry Crunch


By Mark LaPedus Faced with huge and unforeseen demand at the 28nm node, leading-edge foundries are scrambling to play catch-up and are boosting their fab capacities at a staggering pace. But analysts warn that 28nm foundry capacity will be tight throughout 2012, and perhaps into 2013, putting some chipmakers in a pinch. Many blame the 28nm foundry capacity shortfall on a combination of t... » read more

The Brave New World Of Modeling TSVs


By Ann Steffora Mutschler With 2D ICs the prevailing notion has been that wire parasitics are relatively self-contained with the exception of very advanced designs running at hundreds of gigahertz. For the most part, the package designer and IC designer lived in their own separate worlds. With the advent of chip stacking using through silicon vias (TSVs), those worlds are being thrust together... » read more

Reverse Engineering


By Ed Sperling Fabs and foundries frequently have been the savior of flawed designs, fixing problems such as power and performance, identifying design issues and often developing solutions to those problems. Over the next couple of process nodes, and in stacked die that will span multiple processes, there will be far fewer saves coming from the back end. Double and triple patterning, stress... » read more
