Defect Challenges Grow At The Wafer Edge


Reducing defects on the wafer edge, bevel, and backside is becoming essential as the complexity of developing leading-edge chips continue to increase, and where a single flaw can have costly repercussions that span multiple processes and multi-chip packages. This is made more difficult by the widespread rollout of such processes as hybrid bonding, which require pristine surfaces, and the gro... » read more

Chip Industry Week in Review


The Biden-Harris Administration announced preliminary terms with HP for $50 million in direct funding under the CHIPs and Science Act to support the expansion and modernization of HP’s existing microfluidics and microelectromechanical systems (“MEMS”) facility in Corvallis, Oregon. CHIPS for America launched the CHIPS Metrology Community, a collaborative initiative designed to advance ... » read more

Blog Review: Aug. 28


Synopsys' Jon Ames checks out how the Ultra Ethernet Consortium aims to revolutionize networking by optimizing Ethernet for the rapidly evolving AI and HPC workloads by addressing critical issues like tail latency that are encountered by machine learning algorithms in large compute clusters. Cadence's Kos Gitchev introduces the DDR5 Multiplexed Rank DIMM (MRDIMM), a memory module technology ... » read more

AI/ML’s Role In Design And Test Expands


The role of AI and ML in test keeps growing, providing significant time and money savings that often exceed initial expectations. But it doesn't work in all cases, sometimes even disrupting well-tested process flows with questionable return on investment. One of the big attractions of AI is its ability to apply analytics to large data sets that are otherwise limited by human capabilities. In... » read more

Metrology And Inspection For The Chiplet Era


New developments and innovations in metrology and inspection will enable chipmakers to identify and address defects faster and with greater accuracy than ever before, all of which will be required at future process nodes and in densely packed assemblies of chiplets. These advances will affect both front-end and back-end processes, providing increased precision and efficiency, combined with a... » read more

Expediting Manufacturing Safe Launch With Big Data AI/ML Analytic Solutions On The Cloud


With highly competitive time-to-market and time-to-volume windows, IC suppliers need to be able to release new product to production (NPI) in a timely manner with competitive manufacturing metrics. Manufacturing yield, test time and quality are important metrics in NPI to Manufacturing safe launch. A powerful yield management system is crucial to achieve the goal metrics.

X-ray Inspection Becoming Essential In Advanced Packaging


X-ray technology is moving into the mainstream of chip manufacturing as complex assemblies and advanced packaging make it increasingly difficult to ensure these devices will work as expected throughout their lifecycles. A single defect in a chiplet or interconnect can transform a complex advanced package into expensive scrap, and the risk only increases as the chip industry shifts from homog... » read more

Precise Control Needed For Copper Plating And CMP


Chipmakers are relying on machine learning for electroplating and wafer cleaning at leading-edge process nodes, augmenting traditional fault detection/classification and statistical process control in order to extend the usefulness of copper interconnects. Copper is well understood and easy to work with, but it is running out of steam. At 5nm and below, copper plating tools are struggling to... » read more

3D Metrology Meets Its Match In 3D Chips And Packages


The pace of innovation in 3D device structures and packages is accelerating rapidly, driving the need for precise measurement and control of feature height to ensure these devices are reliable and perform as expected throughout their lifetimes. Expansion along the z axis is already well underway. One need look no further than the staircase-like 3D NAND stacks that rise like skyscrapers to p... » read more
