Nearly Invisible: Defect Detection Below 5nm


Detecting sub-5nm defects creates huge challenges for chipmakers, challenges that have a direct impact on yield, reliability, and profitability. In addition to being smaller and harder to detect, defects are often hidden beneath intricate device structures and packaging schemes. Moreover, traditional optical and electrical probing methods, trusted for decades, are proving inadequate against ... » read more

Need For KGD Drives Singulated Die Screening


The move to multi-die packaging is driving chipmakers to develop more cost-effective ways to ensure only known-good die are integrated into packages, because the price of failure is significantly higher than with a single die. Better methods for inspecting and testing these devices are already starting to roll out. High-throughput infrared inspection is capable of catching more sub-surface d... » read more

First-Time Silicon Success Plummets


First-time silicon success is falling sharply due to rising complexity, the need for more iterations as chipmakers shift from monolithic chips to multi-die assemblies, and an increasing amount of customization that makes design and verification more time-consuming. Details from a new functional verification survey[1] highlight the growing difficulty of developing advanced chips that are both... » read more

Big Changes Ahead For Interposers And Substrates


Interposers and substrates are undergoing a profound transformation from intermediaries to engineered platforms responsible for power distribution, thermal management, high-density interconnects, and signal integrity in the most advanced computing systems. This shift is being driven by AI, high-performance computing (HPC), and next-generation communications, where the need for heterogeneous ... » read more

AI And Semiconductor In Reciprocity


In today’s rapidly advancing technological era, AI has become a powerful catalyst for innovation and progress. Advanced semiconductor packaging plays a crucial role in supporting AI development, while AI applications create new semiconductor demands and drive the development of semiconductor technologies, with both complementing each other. Semiconductor packaging: The bridge between chip an... » read more

The Rise Of Thin Wafer Processing


The shift from planar SoCs to 3D-ICs and advanced packages requires much thinner wafers in order to improve performance and reduce power, reducing the distance that signals need to travel and the amount of energy needed to drive them. Markets calling for ultrathin wafers are growing. The combined thickness of an HBM module with 12 DRAM dies and a base logic chip is still less than that of a ... » read more

Sustainable AI Systems For Energy-Efficient Computing


By Pushkar Apte, Jim Sexton, and Melissa Grupen-Shemansky The world is abuzz with the new opportunities being created by artificial intelligence (AI), enabled by the availability of unprecedented amounts of data. AI runs on the semiconductor engine, and in turn, creates a rising demand for semiconductor chips. The semiconductor industry is predicted to reach $1 trillion in revenue by 2030 ... » read more

Optimizing Data Movement In SoCs And Advanced Packages


The amount of data that needs to move around a chip is growing exponentially, driven by the rollout of AI and more sensors everywhere. There may be hundreds of IP blocks, more compute elements, and many more wires to contend with. Andy Nightingale, vice president of product management and marketing at Arteris, talks about the demand for low-latency on-chip communication in increasingly complex ... » read more

Chiplets Add New Power Issues


Delivering and managing power are becoming key challenges in the rollout of chiplets, adding significantly to design complexity and forcing chipmakers to weigh tradeoffs that can have a big impact on the performance, reliability, and the overall cost of semiconductors. Power is a concern for every chip and chiplet design, even if the specifics differ based on the application. Systems vendors... » read more

New Innovative Way To Functionally Verify Heterogeneous 2D/3D Package Connectivity


Historically, IC package design has been a relatively simple task which allowed the die bumps to be fanned out to a geometry suitable for connecting to a printed circuit board. The package netlist was often captured by the package designer, typically using Excel to manually assign net names to the desired die bumps and BGA balls to achieve the intended connection. Modern package and interpos... » read more
