Regional Shifts Supply chains are moving away from China. Apple, Honda, and Mazda are in line to diversify their manufacturing across different regions, according to one report. Another report says Apple plans to manufacture some of its new iPhone 14s in India. Mexico wants to be part of U.S.’s drive to move chip manufacturing closer to home, hosting American financiers to discuss elect... » read more

Is There A Limit To The Number of Layers In 3D-NAND?
By Karen Heyman - 24 Aug, 2022 - Comments: 1

Memory vendors are racing to add more layers to 3D NAND, a competitive market driven by the explosion in data and the need for higher-capacity solid state drives and faster access time. Micron already is filling orders for 232-layer NAND, and not to be outdone, SK Hynix announced that it will begin volume manufacturing 238-layer 512Gb triple level cell (TLC) 4D NAND in the first half of next... » read more

The U.S. Commerce Department issued export controls on key technologies, including gallium oxide (Ga2O3) and diamond substrates, which are used at high voltages and temperatures, as well as EDA tools specifically developed for GAA FETs. It's not clear how this will impact EDA companies, because many of the tools that will be used for designing for GAA FETs already are in use today for finFETs. ... » read more

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

Tradeoffs In Archiving Data
By Karen Heyman - 11 Aug, 2022 - Comments: 0

If you’ve ever had to sort through old technical documents, wondering what still has value and what can be safely tossed, you can identify with the quandary of Thomas Levy, UCSD professor of anthropology and co-founder of the field of cyber-archaeology. Staring at thousands of pieces of pottery in a Jordanian dessert, he erred on the side of keeping it all. “My personal perspective when ... » read more

Nanosheet FETs Drive Changes In Metrology And Inspection
By Karen Heyman - 09 Aug, 2022 - Comments: 0

In the Moore’s Law world, it has become a truism that smaller nodes lead to larger problems. As fabs turn to nanosheet transistors, it is becoming increasingly challenging to detect line-edge roughness and other defects due to the depths and opacities of these and other multi-layered structures. As a result, metrology is taking even more of a hybrid approach, with some well-known tools moving... » read more

Post-CHIPS Act Micron is discussing a potential new fab that could employ thousands of workers, following the passage of the Chips and Science Act. Idaho is hoping it will be built near its headquarters facilities in Boise, but Micron hasn’t committed publicly. Rob Beard, senior vice president, general counsel and corporate secretary at Micron, told the Idaho Statesman the company is consi... » read more

The U.S. Congress approved the CHIPS Act, a mammoth bipartisan achievement the New York Times called “the most significant government intervention in industrial policy in decades.” As passed, the full package — now called the Chips and Science Act — contains $52 billion in direct assistance for the semiconductor industry, along with $24 billion in tax incentives. In addition, the bill c... » read more

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

Fab capacity STMicroelectronics and GlobalFoundries inked a deal to build a new jointly-operated 300mm fab adjacent to ST’s existing 300mm facility in Crolles, France. This facility is targeted to ramp at full capacity by 2026, with up to 620,000 300mm wafer per year production at full build-out (~42% ST and ~58% GF). The new facility will support several technologies, with a special focus... » read more
