Inside Intel’s Ambitious Roadmap
By Mark LaPedus and Ed Sperling - 23 Aug, 2021 - Comments: 2

Ann Kelleher, senior vice president and general manager of Technology Development at Intel, sat down with Semiconductor Engineering to talk about the company’s new logic roadmap, as well as lithography, packaging, and process technology. What follows are excerpts of that discussion. SE: Intel recently disclosed its new logic roadmap. Beyond Intel 3, the company is working on Intel 20A. Wit... » read more

Angstrom-Level Measurements With AFMs
By Mark LaPedus - 19 Aug, 2021 - Comments: 0

Competition is heating up in the atomic force microscopy (AFM) market, where several vendors are shipping new AFM systems that address various metrology challenges in packaging, semiconductors and other fields. AFM, a small but growing field that has been under the radar, involves a standalone system that provides surface measurements on structures down to the angstrom level. (1 angstrom = 0... » read more

Stacked Nanosheets And Forksheet FETs
By Katherine Derbyshire - 19 Aug, 2021 - Comments: 0

What comes next after gate-all-around FETs is still being worked out, but it likely will involve some version of stacked nanosheets. The design of advanced transistors is a tradeoff. On one hand, it takes less gate capacitance to control a thin channel. On the other hand, thin channels can’t carry as much drive current. Stacked nanosheet designs seek to reconcile these two objectives by... » read more

Current And Future Packaging Trends
By Mark LaPedus - 19 Aug, 2021 - Comments: 1

Semiconductor Engineering sat down to discuss IC packaging technology trends and other topics with William Chen, a fellow at ASE; Michael Kelly, vice president of advanced packaging development and integration at Amkor; Richard Otte, president and CEO of Promex, the parent company of QP Technologies; Michael Liu, senior director of global technical marketing at JCET; and Thomas Uhrmann, directo... » read more

Always On, Always At Risk
By Ed Sperling - 18 Aug, 2021 - Comments: 0

Always-on devices are everywhere, and each of them is a potential target for hackers. While many people associate always-on devices with smart speakers such as an Amazon Alexa or Google Home, or a connected security camera, that's only one component in a system. There's a broader infrastructure behind those devices. So even if you power down a digital assistant/smart speaker, everything it's... » read more

Impact Of GAA Transistors At 3/2nm
By Brian Bailey - 16 Aug, 2021 - Comments: 2

The chip industry is poised for another change in transistor structure as gate-all-around (GAA) FETs replace finFETs at 3nm and below, creating a new set of challenges for design teams that will need to be fully understood and addressed. GAA FETs are considered an evolutionary step from finFETs, but the impact on design flows and tools is still expected to be significant. GAA FETs will offer... » read more

Lowering Energy Per Bit
By Ann Mutschler - 12 Aug, 2021 - Comments: 0

Energy is emerging as a focal point in chip and system design, but solving energy-related issues needs to be dealt with on a much broader scale than design teams typically see. Energy is the amount of power consumed over a period of time to perform a given task, but reducing energy is a lot different than reducing power. It affects everything from operational costs and system performance to ... » read more

Adding Circuit Aging To Variability
By Brian Bailey - 12 Aug, 2021 - Comments: 0

Moving to a smaller node usually means another factor becomes important. The industry has become accustomed to doing process, temperature, voltage (PVT) corner analysis, but now it has to add aging into that mix. The problem is that planning for circuit aging is no longer a purely statistical process. Aging is dependent on activity over the lifetime of the device. Tools need to be modified a... » read more

The Search For 5G mmWave Filters
By Bryon Moyer - 12 Aug, 2021 - Comments: 0

Cellular telephone technology takes advantage of a large number of frequency bands to provide ever-increasing bandwidth for mobile use. Each of those bands needs a filter to keep its signals separate from other bands, but the filter technologies in current use for cellphones may not scale up to the full millimeter-wave (mmWave) range planned for 5G. “MmWave will happen,” said Mike Eddy, ... » read more

Has Computational Storage Finally Arrived?
By Andy Patrizio - 11 Aug, 2021 - Comments: 2

The idea behind computational storage is not new. It’s just that like so many concepts, the idea has been well ahead of the technology. In a nutshell, computational storage brings processing power to the storage level. It eliminates the need to load data from the storage system into memory for processing. Moving data between storage and compute resources is inefficient and computational sy... » read more
