A Framework For Improving Current Defect Inspection Techniques For Advanced Nodes


A technical paper titled “Improved Defect Detection and Classification Method for Advanced IC Nodes by Using Slicing Aided Hyper Inference with Refinement Strategy” was published by researchers at Ghent University, imec, and SCREEN SPE. Abstract: "In semiconductor manufacturing, lithography has often been the manufacturing step defining the smallest possible pattern dimensions. In recent ... » read more

Chip Industry Week In Review


By Jesse Allen, Karen Heyman, and Liz Allan Japan's Rapidus and the University of Tokyo are teaming up with France's Leti to meet its previously announced mass production goal of 2nm chips by 2027, and chips in the 1nm range in the 2030s. Rapidus was formed in 2022 with the support of eight Japanese companies — Sony, Kioxia, Denso, NEC, NTT, SoftBank, Toyota, and Mitsubishi's banking arm, ... » read more

Increasing AI Energy Efficiency With Compute In Memory


Skyrocketing AI compute workloads and fixed power budgets are forcing chip and system architects to take a much harder look at compute in memory (CIM), which until recently was considered little more than a science project. CIM solves two problems. First, it takes more energy to move data back and forth between memory and processor than to actually process it. And second, there is so much da... » read more

Chip Industry Week In Review


By Jesse Allen, Gregory Haley, and Liz Allan Bosch, Infineon, and NXP were cleared in Germany to each acquire 10% of the European Semiconductor Manufacturing Co. (ESMC), established by TSMC, solidifying the supply chain against future shortages, particularly for automotive chips. “ESMC intends to build and operate another large semiconductor factory in Dresden, in which the three Europ... » read more

Rethinking Design, Workflow For 3D


In the 3D world, where NAND has hundreds of layers and packages come in intricate stacks, fresh graduates and veteran engineers alike are being confronted with design challenges that require a rethinking of both classic designs and traditional workflows, but without breaking the laws of physics. “There are pockets of things that have been on 3D for quite some time,” said Kenneth Larson, ... » read more

Gearing Up For Hybrid Bonding


Hybrid bonding is becoming the preferred approach to making heterogeneous integration work, as the semiconductor industry shifts its focus from 2D scaling to 3D scaling. By stacking chiplets vertically in direct wafer-to-wafer bonds, chipmakers can leapfrog attainable interconnection pitch from 35µm in copper micro-bumps to 10µm or less. That reduces signal delay to negligible levels and e... » read more

Big Changes Ahead For Photomask Technology


The move to curvilinear shapes on photomasks is gaining steam after years of promise as a way of improving yield, lowering defectivity, and reducing wasted space on a die — all of which are essential for both continued scaling and improved reliability in semiconductors. Interest in this approach ran high at this year's SPIE Photomask Technology + EUV Lithography Conference. Put simply, cur... » read more

Chip Industry Week In Review


By Jesse Allen, Liz Allan, and Gregory Haley A potential government shutdown beginning in November would be "massively disruptive" for the Commerce Department as it continues to disburse critical funding featured in the CHIPS Act to boost semiconductor research and development in the U.S., according to Secretary Gina Raimondo. Global semiconductor industry sales totaled $44 billion in Aug... » read more

Building Better Bridges In Advanced Packaging


The increasing challenges and rising cost of logic scaling, along with demands for an increasing number of features, are pushing more companies into advanced packaging. And while that opens up a slew of new options, it also is causing widespread confusion over what works best for different processes and technologies. At its core, advanced packaging depends on reliable interconnects, well-def... » read more
