Interconnect Challenges Grow


Qualcomm outlined the technology challenges facing mobile chip suppliers at a recent event. In no particular order, the challenges include the usual suspects—area scaling, power reduction, performance and cost. Another concern for Qualcomm is an often-overlooked part of the equation—the backend-of-the-line (BEOL). In chip production, the BEOL is where the interconnects are formed within ... » read more

Why Would IBM Sell Its Semi Group?


Rumors are always just rumors until proven otherwise in business, but in the case of IBM’s semiconductor business, hints about the sale of its semiconductor business are particularly noteworthy. Much has changed since the days when IBM—as International Business Machines—went head-to-head with AT&T’s quasi-public Bell Labs and Xerox’s Palo Alto Research Center (PARC). The breakup of... » read more

Are Processors Running Out Of Steam?


In 2004, Intel introduced a new line of Pentium chips that ran at 3.6GHz. Fast forward to today, and the company’s i7 processors run at 3.5GHz with a Turbo Boost to 3.9GHz. There have been many improvements in the meantime. There is more cache and dramatically faster access to data stored in that cache. And there are more cores with improved coherency between them. But the big problem is p... » read more

The Week In Review: System-Level Design


Cadence bought TranSwitch’s high-speed interface IP assets. TranSwitch, which made chips for communications equipment, filed for bankruptcy in November. (The company’s Web site is no longer active.) Cadence also won a deal with Microsoft, which will use Tensilica processors in the new Xbox One audio subsystem. And Cadence rolled out HiFi Audio Tunneling for Android, which takes advantage of... » read more

Manufacturing Bits: Feb. 11


Monolithic 3D SRAM project A group of companies have started a research project to propel the development of monolithic 3D chip technology. The research project, called COMPOSE³, involves the ability to stack transistors vertically. Within three years, the group hopes to unveil a proof of concept for building the world’s first 14nm, 3D-stacked SRAM cell based on III-V materials. Co... » read more

Week In Review: Manufacturing, Design, Test


This is no surprise, but it could be the end of an era. IBM is exploring a sale of its semiconductor business, according to FT.com. A survey, conducted by Harris Interactive on behalf of Crucial.com, revealed that when asked to choose between these two specific types of men, 84% of women who prefer to be involved with men prefer their male love interest to be "super handy" with computers an... » read more

Manufacturing Bits: Feb. 4


Secrets of mass variation The General Conference on Weights and Measures will soon approve a plan to redefine the kilogram and other measurement units. The new definition for the kilogram will be based on the fixed numerical values of Planck’s constant (h). Supposedly, the new definition will solve the current problem. The kilogram is the only SI unit that is still described as an artif... » read more

Week In Review: Manufacturing, Design, Test


The technology of 3D "bioprinting" (the medical application of 3D printing to produce living tissue and organs) is advancing so quickly that it will spark a major ethical debate on its use by 2016, according to Gartner. At the same time, 3D printing of non-living medical devices such as prosthetic limbs, combined with a burgeoning population and insufficient levels of healthcare in emerging mar... » read more

A Perspective On Open Process Specification


It is the job of the Process Design Kit (PDK) engineers to deliver a high-quality PDK that properly represents the process requirements and constraints and supports the design flows used by their customers. The PDK engineer takes multiple inputs describing the process and the devices and circuitry in the process and generates the output in the form of OpenAccess technology libraries (techDB), d... » read more

What’s After CMOS?


Chipmakers continue to scale the CMOS transistor to finer geometries, but the question is for how much longer. The current thinking is that the CMOS transistor could scale at least to the 3nm node in the 2021 timeframe. And then, CMOS could run out of gas, prompting the need for a new switch technology. So what’s after the CMOS-based transistor? Carbon nanotubes and graphene get the most a... » read more
