Backside Power Delivery Adds New Thermal Concerns


As the semiconductor industry gears up for backside power delivery at the 2nm node, implementation of the technology requires a re-thinking of established design practices. While some EDA tools are already qualified, designers must acquaint themselves with new issues, including making place-and-route more thermal-aware and how to manage heat dissipation with less shielding and thinner substr... » read more

Chip Industry Week In Review


By Adam Kovac, Karen Heyman, and Liz Allan. India approved the construction of two fabs and a packaging house, for a total investment of about $15.2 billion, according to multiple sources. One fab will be jointly owned by Tata and Taiwan's Powerchip. The second fab will be a joint investment between CG Power, Japan's Renesas Electronics, and Thailand's Stars Microelectronics. Tata will run t... » read more

Backside Power Delivery Gears Up For 2nm Devices


The top three foundries plan to implement backside power delivery as soon as the 2nm node, setting the stage for faster and more efficient switching in chips, reduced routing congestion, and lower noise across multiple metal layers. The benefits of using this approach are significant. By delivering power using slightly fatter, less resistive lines on the backside, rather than inefficient fro... » read more

Chip Industry Week In Review


By Jesse Allen, Gregory Haley, and Liz Allan Intel officially launched Intel Foundry this week, claiming it's the "world's first systems foundry for the AI era." The foundry also showed off a more detailed technology roadmap down to expanded 14A process technology. Intel CEO Pat Gelsinger noted the foundry will be separate from the chipmaker, utilize third-party chiplets and IP, and leverage... » read more

Building CFETs With Monolithic And Sequential 3D


Successive versions of vertical transistors are emerging as the likely successor to finFETs, combining lower leakage with significant area reduction. A stacked nanosheet transistor, introduced at N3, uses multiple channel layers to maintain the overall channel length and necessary drive current while continuing to reduce the standard cell footprint. The follow-on technology, the CFET, pushes... » read more

Chip Industry Week In Review


By Susan Rambo, Karen Heyman, and Liz Allan. Renesas plans to acquire Altium, maker of PCB design software, for $5.9 billion. In a conference call, Renesas CEO Hidetoshi Shibata cited Altium's PCB design software and digital twin virtual modeling as key components of its future strategy. "I believe it will generate transformational value for our combined customers and our stakeholders," Shib... » read more

SRAM Scaling Issues, And What Comes Next


The inability of SRAM to scale has challenged power and performance goals forcing the design ecosystem to come up with strategies that range from hardware innovations to re-thinking design layouts. At the same time, despite the age of its initial design and its current scaling limitations, SRAM has become the workhorse memory for AI. SRAM, and its slightly younger cousin DRAM, have always co... » read more

By Jesse Allen, Linda Christensen, and Liz Allan.  The Biden administration plans to invest more than $5B  for semiconductor R&D and workforce support, including in the National Semiconductor Technology Center (NSTC), as part of the rollout of the CHIPS Act. Today's announcement included at least hundreds of millions for the NSTC workforce efforts, including creating a Workforce Cente... » read more

Evaluation of Cache Replacement Policies Using Various Typical Simulation Approaches


A technical paper titled “Improving the Representativeness of Simulation Intervals for the Cache Memory System” was published by researchers at Complutense University of Madrid, imec, and KU Leuven. Abstract: "Accurate simulation techniques are indispensable to efficiently propose new memory or architectural organizations. As implementing new hardware concepts in real systems is often not... » read more
