Removing Barriers For End-To-End Analytics


Parties are coming together, generating guidelines for sharing data from IC design and manufacturing through end of life, setting the stage for true end-to-end analytics. While the promise of big data analytics is well understood, data sharing through the semiconductor supply chain has been stymied by an inability to link together data sources throughout the lifecycle of a chip, package, or ... » read more

The Race To Zero Defects In Auto ICs


Assembly houses are fine-tuning their methodologies and processes for automotive ICs, optimizing everything from inspection and metrology to data management in order to prevent escapes and reduce the number of costly returns. Today, assembly defects account for between 12% and 15% of semiconductor customer returns in the automotive chip market. As component counts in vehicles climb from the ... » read more

New Method For BEOL Overlay And Process Margin Characterization


This paper presents a new method, design for inspection (DFI) to characterize overlay. Using design-assisted voltage contrast measurement, the method enables in-line test and monitoring of process induced OVL and CD variation of backend-of line (BEOL) features with litho-etch-lithoetch (LELE) patterning. While only some of the features of multi-color patterning scheme are chosen to be aligned d... » read more

Week in Review: Manufacturing, Test


Industry Numbers NAND flash memory is forecast to hit US $83 billion this year, an increase of 24%. DRAM is projected to hit $118 billion, up 25%, according to a recent Yole report. Both are historic records. DRAM and NAND revenues are expected to be a $260 billion market in 2027 (combined), with advanced technologies such as EUV lithography, hybrid bonding and 3D DRAM driving this. SEMI in... » read more

Hidden Impacts Of Software Updates


Over-the-air updates can reduce obsolescence over longer chip and system lifetimes, but those updates also can impact reliability, performance, and affect how various resources such as memory and various processing elements are used. The connected world is very familiar with over-the-air (OTA) updates in smart phones and computers, where the software stack — firmware, operating systems, dr... » read more

Where And When End-to-End Analytics Works


With data exploding across all manufacturing steps, the promise of leveraging it from fab to field is beginning to pay off. Engineers are beginning to connect device data across manufacturing and test steps, making it possible to more easily achieve yield and quality goals at lower cost. The key is knowing which process knob will increase yield, which failures can be detected earlier, and wh... » read more

Novel E-Beam Techniques For Inspection And Monitoring


In this paper, we report an advanced e-beam defect inspection tool (eProbe®250) and the Design-for-Inspection™ (DFI) system that has been built and deployed by PDF Solutions down to 4nm FinFET technology nodes. This tool has a very high throughput which allows for in-line inspection of nanometer-level defects in the most advanced technology nodes. We also present eProbe applications for... » read more

Automotive, mobility Stellantis is buying Share Now, a car sharing service owned by BMW and Mercedes-Benz. Through the acquisition, Stellantis will be adding 3.4 million car sharing customers, 10,000 vehicles, and 14 new European cities to its Free2move car sharing service, which currently has 2 million users, 2,500 vehicles, and has 7 “mobility hubs” in the U.S. and Europe. ShareNow was a... » read more

Week In Review: Manufacturing, Test


It's earnings season, and despite widespread reports of capacity issues and shortages, the chip industry turned in relatively solid results across the board. Intel exceeded January guidance for Q1, reporting first-quarter GAAP revenue of $18.4 billion, a 7% year-over-year decrease, and a 1% decrease year-over-year on non-GAAP basis. Record revenue was achieved in the Network and Edge Group, ... » read more
