Affordable And Comprehensive Testing Of 3D Stacked Die Devices


Developers of high-end semiconductor products who face manufacturing limitations with respect to die sizes are investing in 3D stacked die technology. These advanced designs already push current design-for-test (DFT) solutions to the limits: tool run time, on-chip area demand, test pattern count, and test time. How then, can designers manage DFT for these new 3D devices? In this paper, we outli... » read more

Can You Afford DFT For 3D Stacked Die?


When existing advanced 2D designs already push the limits of design-for-test (DFT) tools, what hope do developers have of managing DFT for 3D devices? Can anyone afford the tool run time, on-chip area demand, pattern count, and test time? The answer, from an array of experts, is yes, there is a path to a scalable, affordable, and comprehensive DFT solution for 3D ICs. Well-covered strategies... » read more

2.5/3D IC Reliability Verification Has Come A Long Way


2.5D/3D integrated circuits (ICs) have evolved into an innovative solution for many IC design and integration challenges. As shown in figure 1, 2.5D ICs have multiple dies placed side-by-side on a passive silicon interposer. The interposer is placed on a ball grid array (BGA) organic substrate. Micro-bumps attach each die to the interposer, and flip-chip (C4) bumps attach the interposer to the ... » read more

Bespoke Silicon Redefines Custom ASICs


Semiconductor Engineering sat down to discuss bespoke silicon and what's driving that customization with Kam Kittrell, vice president of product management in the Digital & Signoff group at Cadence; Rupert Baines, chief marketing officer at Codasip; Kevin McDermott, vice president of marketing at Imperas; Mo Faisal, CEO of Movellus; Ankur Gupta, vice president and general manager of Siemens... » read more

Hybrid Bonding Moves Into The Fast Lane


The industry’s unquenchable thirst for I/O density and faster connections between chips, particularly logic and cache memory, is transforming system designs to include 3D architectures, and hybrid bonding has become an essential component in that equation. Hybrid bonding involves die-to-wafer or wafer-to-wafer connection of copper pads that carry power and signals and the surrounding diele... » read more

What Future Processors Will Look Like


Mark Papermaster, CTO at AMD, sat down with Semiconductor Engineering to talk about architectural changes that are required as the benefits of scaling decrease, including chiplets, new standards for heterogeneous integration, and different types of memory. What follows are excerpts of that conversation. SE: What does a processor look like in five years? Is it a bunch of chips in a package? I... » read more

Software Infrastructure For Silicon Lifecycle Management


Semiconductor technology continues to deliver higher levels of logic density in the era of nanometer processes. System-on-chip (SoC) teams can deliver even higher functionality when coupled with the massive integration possibilities of three-dimensional integrated circuit (3DIC) architectures. However, this growth must be matched by increases in capabilities and productivity in the collection a... » read more

Electromagnetic Simulation And 3D-IC Interposers


By Matt Commens, Juliano Mologni, and Pete Gasperini Today’s 3D integrated circuit (3D-IC) technology is the culmination of 40 years of research in universities and laboratories scattered across the globe. Beginning with dynamic random-access memory (DRAM) deployments that appeared on the market a decade ago, 3D-IC has since expanded its reach. It is now decisively beginning to achieve the... » read more

Chipmaking In The Third Dimension


Every few months, new and improved electronics are introduced. They’re typically smaller, smarter, faster, have more bandwidth, are more power-efficient, etc. — all thanks to a new generation of advanced chips and processors. Our digital society has come to expect this steady drip of new devices as sure as the sun will rise tomorrow. Behind the scenes, however, engineers are working feve... » read more

Keeping IC Packages Cool


Placing multiple chips into a package side-by-side can alleviate thermal issues, but as companies dive further into die stacking and denser packaging to boost performance and reduce power, they are wrestling with a whole new set of heat-related issues. The shift to advanced packaging enables chipmakers to meet demands for increasing bandwidth, clock speeds, and power density for high perform... » read more
