Week In Review: Manufacturing, Test


Government funding President Biden signed the CHIPS and Science Act into law on Tuesday, saying “America is back and leading the way.” That same day Micron touted a $40 billion investment through to 2030, which it expects will create 40,000 American jobs. “This legislation will enable Micron to grow domestic production of memory from less than 2% to up to 10% of the global market in t... » read more

Making The Most Of Data Lakes


Having all the semiconductor data available is increasingly necessary for improving manufacturability, yield, and ultimately the reliability of end devices. But without sufficient knowledge of relationships between data from different processes and computationally efficient data structures, the value of any data is significantly reduced. In the semiconductor industry, reducing waste, decreas... » read more

Week In Review: Manufacturing, Test


Ramping capacity Samsung is considering building as many as 11 fabs in central Texas, investing an estimated $200 billion and creating as many as 10,000 jobs. The plans came to light when the company filed paperwork for tax breaks. Samsung already has broken ground on a new $17 billion fab in Taylor, Texas. The remaining nine fabs, including two in nearby Austin, would be built over the next c... » read more

Finding Frameworks For End-To-End Analytics


End-to-end analytics can improve yield and ROI on tool purchases, but reaping those benefits will require common data formats, die traceability, an appropriate level of data granularity — and a determination of who owns what data. New standards, guidelines, and consortium efforts are being developed to remove these barriers to data sharing for analytics purposes. But the amount of work req... » read more

E-beam’s Role Grows For Detecting IC Defects


The perpetual march toward smaller features, coupled with growing demand for better reliability over longer chip lifetimes, has elevated inspection from a relatively obscure but necessary technology into one of the most critical tools in fab and packaging houses. For years, inspection had been framed as a battle between e-beam and optical microscopy. Increasingly, though, other types of insp... » read more

Variation Making Trouble In Advanced Packages


Variation is becoming increasingly problematic as chip designs become more heterogeneous and targeted by application, making it difficult to identify the root cause of problems or predict what can go wrong and when. Concerns about variation traditionally have been confined to the most advanced nodes, where transistor density is highest and where manufacturing processes are still being fine-t... » read more

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
