Today at the IEEE International Electron Devices Meeting (IEDM) 2024, Intel Foundry unveiled new breakthroughs to help drive the semiconductor industry forward into the next decade and beyond. Intel Foundry showcased new material advancements that help improve interconnections within a chip, resulting in up to 25% capacitance by using subtractive ruthenium. Intel Foundry also was first to report a 100x throughput improvement using a heterogeneous integration solution for advanced packaging to enable ultra-fast chip-to-chip assembly. And to further drive gate-all-around (GAA) scaling, Intel Foundry demonstrated work with silicon RibbonFET CMOS and with gate oxide module for scaled 2D FETs for improved device performance.

"Intel Foundry continues to help define and shape the roadmap for the semiconductor industry. Our latest breakthroughs underscore the company's commitment to delivering cutting-edge technology developed in the U.S., positioning us well to help balance the global supply chain and restore domestic manufacturing and technology leadership with the support of the U.S. CHIPS Act," says Sanjay Natarajan, Intel senior vice president and general manager of Intel Foundry Technology Research.

Intel has prepared "Jaguar Shores," its "next-next" generation AI and HPC accelerator, successor to its upcoming "Falcon Shores" GPU. Revealed during a technical workshop at the SC2024 conference, the chip was unveiled by Intel's Habana Labs division, albeit unintentionally. This announcement positions Jaguar Shores as the successor to Falcon Shores, which is scheduled to launch next year. While details about Jaguar Shores remain sparse, its designation suggests it could be a general-purpose GPU (GPGPU) aimed at both AI training, inferencing, and HPC tasks. Intel's strategy aligns with its push to incorporate advanced manufacturing nodes, such as the 18A process featuring RibbonFET and backside power delivery, which promise significant efficiency gains, so we can expect to see upcoming AI accelerators incorporating these technologies.

Intel's AI chip lineup has faced numerous challenges, including shifting plans for Falcon Shores, which has transitioned from a CPU-GPU hybrid to a standalone GPU, and cancellation of Ponte Vecchio. Despite financial constraints and job cuts, Intel has maintained its focus on developing cutting-edge AI solutions. "We continuously evaluate our roadmap to ensure it aligns with the evolving needs of our customers. While we don't have any new updates to share, we are committed to providing superior enterprise AI solutions across our CPU and accelerator/GPU portfolio." an Intel spokesperson stated. The announcement of Jaguar Shores shows Intel's determination to remain competitive. However, the company faces steep competition. NVIDIA and AMD continue to set benchmarks with performant designs, while Intel has struggled to capture a significant share of the AI training market. The company's Gaudi lineup ends with third generation, and Gaudi IP will get integrated into Falcon Shores.

Yesterday, Intel launched its Xeon 6 family of server processors based on P-cores manufactured on Intel 3 node. While the early reviews seem promising, Intel is preparing a more advanced generation of processors that will make or break its product and foundry leadership. Codenamed "Clearwater Forest," these CPUs are expected to be the first high-volume production chips based on the Intel 18A node. We have pictures of the five-tile Clearwater Forest processor thanks to Tom's Hardware. During the Enterprise Tech Tour event in Portland, Oregon, Tom's Hardware managed to take a picture of the complex Clearwater Forest design. With compute logic built on 18A, this CPU uses Intel's 3-T process technology, which serves as the foundation for the base die, marking its debut in this role. Compute dies are stacked on this base die, making the CPU building more complex but more flexible.

The Foveros Direct 3D and EMIB technologies enable large-scale integration on a package, achieving capabilities that previous monolithic single-chip designs could not deliver. Other technologies like RibbonFET and PowerVia will also be present for Clearwater Forest. If everything continues to advance according to plan, we expect to see this next-generation CPU sometime next year. However, it is crucial to note that if this CPU shows that the high-volume production of Intel 18A is viable, many Intel Foundry customers would be reassured that Intel can compete with TSMC and Samsung in producing high-performance silicon on advanced nodes at scale.

Intel has announced the cancellation of its 20A node for Foundry customers, as well as shifting majority of Arrow Lake production to external foundries. The tech giant will instead focus its resources on the more advanced 18A node while relying on external partners for Arrow Lake production, likely tapping TSMC or Samsung for their 2 nm nodes. The decision follows Intel's successful release of the 18A Process Design Kit (PDK) 1.0 in July, which garnered positive feedback from the ecosystem, according to the company. Intel reports that the 18A node is already operational, booting operating systems and yielding well, keeping the company on track for a 2025 launch. This early success has enabled Intel to reallocate engineering resources from 20A to 18A sooner than anticipated. As a result, the "Arrow Lake processor family will be built primarily using external partners and packaged by Intel Foundry".

The 20A node, while now cancelled for Arrow Lake, has played a crucial role in Intel's journey towards 18A. It served as a testbed for new techniques, materials, and transistor architectures essential for advancing Moore's Law. The 20A node successfully integrated both RibbonFET gate-all-around transistor architecture and PowerVia backside power delivery for the first time, providing valuable insights that directly informed the development of 18A. Intel's decision to focus on 18A is also driven by economic factors. With the current 18A defect density already at D0 <0.40, the company sees an opportunity to optimize its engineering investments by transitioning now. However, challenges remain, as evidenced by recent reports of Broadcom's disappointment in the 18A node. Despite these hurdles, Intel remains optimistic about the future of its foundry services and the potential of its advanced manufacturing processes. The coming months will be crucial as the company works to demonstrate the capabilities of its 18A node and secure more partners for its foundry business.

Intel today announced that its lead products on Intel 18A, Panther Lake (AI PC client processor) and Clearwater Forest (server processor), are out of the fab and have powered-on and booted operating systems. These milestones were achieved less than two quarters after tape-out, with both products on track to start production in 2025. The company also announced that the first external customer is expected to tape out on Intel 18A in the first half of next year.

"We are pioneering multiple systems foundry technologies for the AI era and delivering a full stack of innovation that's essential to the next generation of products for Intel and our foundry customers. We are encouraged by our progress and are working closely with customers to bring Intel 18A to market in 2025." -Kevin O'Buckley, Intel senior vice president and general manager of Foundry Services

Intel Foundry Services (IFS) and Cadence Design Systems Inc. today announced a multiyear strategic agreement to jointly develop a portfolio of key customized intellectual property (IP), optimized design flows and techniques for Intel 18A process technology featuring RibbonFET gate-all-around transistors and PowerVia backside power delivery.

"We're very excited to expand our partnership with Cadence to grow the IP ecosystem for IFS and provide choice for customers," said Stuart Paann, Intel senior vice president and general manager of IFS. "We will leverage Cadence's world-class portfolio of leading IP and advanced design solutions to enable our customers to deliver high-volume, high-performance and power-efficient SoCs on Intel's leading-edge process technologies."

During the 69th annual IEEE International Electron Devices Meeting (IEDM), Intel demonstrated some of its latest transistor design and manufacturing advancements. The first one in line is the 3D integration of transistors. According to Intel, the company has successfully stacked complementary field effect transistors (CFET) at a scaled gate pitch down to 60 nm. With CFETs promising thinner gate channels, the 3D stacked CFET would allow for higher density by going vertically and horizontally. Intel's 7 node has a 54 nm gate pitch, meaning CFETs are already close to matching production-ready nodes. With more time and development, we expect to see 3D stacked CFETs in the production runs in the coming years.

Next, Intel has demonstrated RibbonFET technology, a novel approach that is the first new transistor architecture since the introduction of FinFET in 2012. Using ribbon-shaped channels surrounded by the gate, these transistors allow for better control and higher drive current at all voltage levels. This allows faster transistor switching speeds, which later lead to higher frequency and performance. The width of these nanoribbon channels can be modulated depending on the application, where low-power mobile applications use less current, making the channels thinner, and high-performance applications require more current, making the channels wider. One stack of nanoribbons can achieve the same drive current as multiple fins found in FinFET but at a smaller footprint.

Marking a milestone in Intel's ongoing manufacturing expansion in Arizona, the company today announced that the initial portion of the cleanroom is "weather tight" and the "blow down" phase has begun at the company's two new leading-edge chip factories on its Ocotillo campus in Chandler, Arizona. This milestone underscores Intel's dedication to advancing its presence in the state and fostering technological innovation.

"Our commitment to Arizona runs deep, and as we expand our operations, we remain dedicated to addressing the growing demand for semiconductors and helping the United States regain its leadership position in this vital industry. This milestone represents the result of great teamwork, proficient teams and exceptional craftsmanship of the tradespeople, and it's thanks to their hard work that we've made such significant progress on our site while keeping our culture of caring and the safety of all as our top priority." -Dan Doron, Intel vice president and general manager of Fab Construction Enterprise
