NAND Flash Targets 1,000 Layers


The chip industry is pushing to quadruple the stack height of 3D NAND flash from 200 layers to 800 layers or more over the next few years, using the additional capacity will help to feed the unending need for more memory of all types. Those additional layers will add new reliability issues a number of incremental reliability challenges, but the NAND flash industry has been steadily increasin... » read more

Optimizing Wafer Edge Processes For Chip Stacking


Stacking chiplets vertically using short and direct wafer-to-wafer bonds can reduce signal delay to negligible levels, enabling smaller, thinner packages with faster memory/processor speeds and lower power consumption. The race is on to implement wafer stacking and die-to-wafer hybrid bonding, now considered essential for stacking logic and memory, 3D NAND, and possibly multi-layer DRAM stac... » read more

Chip Industry Week In Review


Concerns mount on the use of American-manufactured semiconductors in Russian weapons, with Analog Devices, AMD, Intel and TI set to testify next week before the U.S. Senate Permanent Subcommittee on Investigations. Also, U.S. and other government agencies issued a joint advisory and more details about ongoing Russian military cyberattacks, espionage, and sabotage. The U.S. Commerce Departmen... » read more

Week In Review: Semiconductor Manufacturing, Test


Chinese memory chip maker YMTC and dozens of other Chinese entities are "at risk" of being added to a trade blacklist as soon as Dec. 6, a U.S. Commerce Department official said in prepared remarks seen by Reuters. SMIC co-CEO Zhao Haijun said on an earnings call that recent export controls from the United States will have an "adverse impact" on the company's production. The U.K. has rule... » read more

Wafer Cleaning Becomes Key Challenge In Manufacturing 3D Structures


Wafer cleaning, once a rather mundane task as simple as dipping wafers in cleaning fluid, is emerging as one of the top major engineering challenges for manufacturing GAA FETs and 3D-ICs. With these new 3D structures — some on the horizon but some already in high-volume manufacturing — semiconductor wafer equipment and materials suppliers in the wet cleaning business are at the epicenter... » read more

How Quickly Can SiC Ramp?


Device makers across the globe are ramping silicon carbide (SiC) manufacturing, with growth set to really take off starting in 2024. It’s been almost five years since Tesla and STMicroelectronics threw down the gauntlet with SiC in the Model 3. Now, no one doubts the market pull for electric vehicles, but consumers are still clamoring for better range and faster charging. SiC devices are a... » read more

Week In Review: Manufacturing, Test


Chipmakers United Microelectronics Corp. (UMC) has announced the readiness of its new 22nm process. The process enables new 22nm designs or allows customers to migrate from 28nm to 22nm. UMC’s 22nm maintains its existing 28nm design architectures. UMC's 22nm process features a 10% area reduction, better power-to-performance ratio and enhanced RF capabilities, compared to the company’s 2... » read more

The Week In Review: Manufacturing


Chipmakers Bloomberg has reported that Broadcom is in talks to acquire Qualcomm for $70 per share or about $90 billion. Qualcomm is attempting to acquire NXP, but Broadcom has its sights on Qualcomm, not NXP. “We think AVGO would want to acquire QCOM assets not NXP,” said Amit Daryanani, an analyst with RBC. Samsung continues to reshuffle its management amid a plethora of changes at t... » read more
