Chip Industry Week In Review


Advanced nodes and packaging AMD announced more than $10B in Taiwan ecosystem investments to scale advanced packaging manufacturing for AI infrastructure. The effort includes EFB-based 2.5D packaging collaborations with ASE and others. AMD also announced the start of its production ramp of its Venice processors on TSMC's 2nm process. Lam Research established a panel-level packaging cen... » read more

AI Accelerators Usher In New Era For IC Test


Key Takeaways The parallelism in AI accelerators enables low latency but complicates failure isolation. HBM can account for 50% of package cost, so known-good stack assurance is critical. DFT and test cooperate to solve final test, singulated die test, SLT, and in-system test for data centers. AI accelerators are used for everything from training large language models to mak... » read more

Beating The Heat In 3D Packages


Key Takeaways: Thermal management is a central design constraint, requiring early, thorough planning. Accurate thermal simulation requires AI-driven adaptive meshing and real-world validation. Innovative STCO strategies can drastically reduce GPU peak temperature. As HPC and AI accelerators push power densities to 1kW and beyond, the heat generated by rapidly switching tran... » read more

An Explosion In Interconnect Complexity


For decades, electronics offered two levels of routing structure to manage signals that originate or terminate in an integrated circuit. Recently, that number has risen to five, and while it adds far more flexibility for structuring electronic equipment, it also brings greater complexity and ratchets up the number of design decisions needed to complete a project. This transition has been evo... » read more

3DKs: Making Headway On Chiplet Standards


The chiplet model has been proven by the early adopters. Large companies that successfully developed chips at leading nodes have integrated multiple chiplets into systems, where the entire silicon cycle is performed in-house. But the industry’s long-term goal of a free and open chiplet marketplace, in which companies of any size can reap the rewards and economies of scale associated with mult... » read more

Chip Industry Week in Review


SEMICON West was held in Phoenix this week, with presentations covering heterogeneous integration, AI, quantum, supply chain resilience, and more. Amid the buzz of the conference, some key manufacturing and test announcements were made this week: The strategic importance of the Phoenix area hub was highlighted. Amkor Technology broke ground this week on its advanced packaging and test camp... » read more

Voltage Regulation Moves Into The Package


Integrated circuits require a variety of voltages and a wide range of currents, typically supplied by voltage regulators. But increasing power density is resulting in higher power delivery losses. Moving those regulators closer to the chips they power can reduce those losses. Co-packaging them holds the most promise, but it comes with challenges. “What people have been talking about, ev... » read more

Chip Industry Week in Review


Microsoft, OpenAI, and NVIDIA warned about power swings and physical damage to power grids increasing from AI training workloads and jointly proposed a multi-pronged approach to stabilize power in AI training data centers. Meanwhile, Anthropic issued a warning about the weaponization of agentic AI in a new 25-page Threat Intelligence report. Key concerns involve the evolution in AI-assisted ... » read more

Reticle Stitching Bumps Up Silicon Interposer Costs


Advanced packaging often relies on silicon interposers to connect chiplets and other components inside a package. The problem is that interposers typically exceed the reticle limit, which adds both complexity and cost. An interposer is essential for 2.5D and 3.5D architectures. As device scaling runs out of steam, chipmakers are decomposing planar SoCs into chiplets and connecting them throu... » read more

Chiplet Interfaces Embrace Failures


Redundancy in chiplet interfaces is now a prerequisite for achieving sufficient yield in high-performance computing devices, which today are packed with tens of thousands of interconnects. And as the number and density of those interconnects increases, the prospects for yield only worsen. For more than two decades, high-speed I/O interfaces have included reliability strategies to manage in-f... » read more
