Scaling The Lowly SRAM


By Mark LaPedus Chipmakers face a multitude of challenges at the 20nm logic node and beyond, including the task of cramming more functions on the same chip without compromising on power and performance. There is one major challenge that is often overlooked in the equation—scaling the lowly static RAM (SRAM). In one key application, SRAM is the component used to make on-chip cache memories... » read more

New Foundry Gold Rush: RF SOI


By Mark LaPedus About every five years or so, a new and hot market emerges in the specialty foundry business that resembles a frenetic gold rush. The last big gold rush occurred around 2008, when more than a dozen foundries jumped into the bipolar-CMOS-DMOS (BCD) market to capitalize on the booming power-management sector. Now, the next gold rush is centering on an emerging technology—th... » read more

FinFETs On SOI


Soitec's Steve Longoria talks with Semiconductor Manufacturing and Design about what's changing at the leading edge of Moore's Law and why those changes are necessary. [youtube vid=K6D39QqJWSU] » read more

3D Integration


By Katherine Derbyshire It’s a central problem of integrated circuit scaling. While transistor delay goes down along with channel length, interconnect delay goes up. The 90 nm technology node featured a transistor delay of about 1.6 ps, while a 1 mm long interconnect wire added about 5x102 ps. For the 22 nm node, the ITRS estimates transistor delay at 0.4 ps, but interconnect delay at abou... » read more

CMOS And SOI Invade RF Front End


By Mark LaPedus The next-generation 4G wireless standard known as long-term evolution (LTE) presents some new and difficult design choices for OEMs. One of the more difficult choices involves the less glamorous, but arguably the most critical part in a handset—the radio-frequency (RF) front-end. Typically, the RF front-end often comes in a module and includes various key components, such ... » read more

Over 50% Of Smart Phones And Tablets Leverage SOI


Posted by Adele Hars, Editor-in-Chief, Advanced Substrate News ~  ~ In a recent press release, the SOI wafer leader Soitec said that chips built on its SOI wafers were found in over half of the smartphones and tablets in the market worldwide. 50%? That’s a lot! How do they figure that? The answer: RF. [caption id="attachment_809" align="alignleft" width="549" caption="As seen here... » read more

The Week In Review: Feb. 25


By Mark LaPedus Is China set to bail out a U.S. government technology darling? Two Chinese automotive companies, Geely and Dongfeng Motor, are reported to have bid between $200 million and $350 million for a majority stake in Fisker, the maker of plug-in hybrid cars. If that happens Fisker—which has $192 million in U.S. federal government loan guarantees—could be headed to China, according... » read more

Smartphones Dial Up New RF Processes


By Mark LaPedus The rapid shift towards smartphones and tablets is driving the need for new and low-power chips at finer geometries. Today, the latest application processors, integrated basebands and other digital cell-phone chips are 28nm planar devices. And it won’t be long before OEMs incorporate 20nm planar and finFET devices in their systems as a means to reduce power and extend batt... » read more

Tradeoffs On The Fly


By Ann Steffora Mutschler With classical bulk planar technology no longer shrinkable, the industry has been honing in on new ways to continue some scaling, achieve extra speed or better power while minimizing leakage. “To overcome the limits [of bulk planar technology] we need a different solution,” explained Giorgio Cesano, technology R&D marketing director at STMicroelectron... » read more

Upping The Ante


The increasing number of research projects under way to solve many of the thorniest issues in the history of semiconductor design and manufacturing are a testament to just how tough the job has become. Never before have there been so many technological roadblocks at the same time—and so many potential options for solving them. Those challenges—or opportunities, as marketing execs like to... » read more
