How Intel Took EMIB From Science Fiction to High Volume: Intel Foundry's Ravi Mahajan
EMIB (Embedded Multi-Die Interconnect Bridge) technology provides a scalable, high-density solution for heterogeneous chip integration by utilizing localized silicon bridges within organic substrates. This approach decouples high-speed I/O from power delivery, allowing for fine-pitch interconnects only where necessary ...

RF Over Plastic Is a Third Option Between Copper and Optics: Point2's Sean Park

MicroVCSELs vs MicroLEDs, a MicroExplainer
Short-reach data center interconnects are transitioning from microLEDs to microVCSELs to address the limitations of copper and the scaling requirements of AI systems. While microLEDs rely on spontaneous emission and suffer from chromatic dispersion that restricts their reach to approximately five meters, microVCSELs ut...

AI Inference Is a Data Movement Problem: Microsoft's Saurabh Dighe on Maia 300
Microsoft’s Maia 300 architecture represents a strategic shift toward inference-first AI infrastructure, designed to maximize token throughput and energy efficiency for planet-scale workloads. Saurabh Dighe, Corporate Vice President of Azure Hardware Systems, details how the system leverages a software-defined data flo...

Synopsys’s Amazon Deal and GPT-Synopsys: Ravi Subramanian
Synopsys is transforming semiconductor design by shifting toward application-optimized IP and integrating agentic AI into the EDA workflow. The recent $1 billion-plus deal with Amazon highlights this transition, where custom, workload-specific IP replaces traditional off-the-shelf standards to meet the extreme performa...
