Defect Evolution In Next Generation, Extreme Ultraviolet Lithography


Extreme ultraviolet (EUV) lithography is a promising next generation lithography technology that may succeed optical lithography at future technology nodes. EUV mask infrastructure and manufacturing of defect-free EUV mask blanks is a key near term challenge in the use of EUV lithography. Virtual fabrication is a computerized technique to perform predictive, three dimensional modeling of sem... » read more

Manufacturing Bits: March 3


Security lithography At the recent SPIE Advanced Lithography conference, Multibeam disclosed more details about its efforts to develop multi-beam direct-write lithography for chip security applications. David Lam, chief executive and chairman of Multibeam, described how multi-beam lithography can be used to help thwart IC counterfeiting and tampering in the market. This lithography technolo... » read more

Week In Review: Manufacturing, Test


SPIE At the SPIE Advanced Lithography conference, Lam Research has introduced a new dry resist technology for extreme ultraviolet (EUV) lithography. Dry resist technology is a new approach to deposit and develop EUV resists. It is a dry deposition technique with alternate compositions and mechanisms. By combining Lam’s deposition and etch process expertise with partnerships with ASML a... » read more

2020 IC Outlook: Uncertainty


After a downturn in 2019, the semiconductor and equipment industries looked promising at the start of 2020. In 2019, the downturn was primarily due to the memory markets, namely DRAM and NAND. Both DRAM and NAND saw lackluster demand and falling prices last year. At the start of 2020, though, the memory markets were beginning to recover. Unlike memory, the logic and foundry markets were s... » read more

Week In Review: Manufacturing, Test


Fab tools The United States is mulling over new trade export restrictions for U.S. fab equipment to China, according to a report from The Wall Street Journal. “Recent press reports suggest the U.S. Department of Commerce is exploring additional measures to limit Huawei's access to U.S. semiconductor capital equipment (SPE) by requiring chip manufacturing plants globally to procure license... » read more

The Risk Of Two Supply Chains


Ever since the Trump administration weaponized trade restrictions against individual companies — first ZTE, then Huawei — China has begun developing a second supply chain for electronics. Inside of China, this is viewed as a necessary step for survival. In April 2018, the U.S. government banned ZTE from sourcing U.S. components for seven years, nearly putting that company out of business... » read more

EDA In The Cloud


Michael White, director of product marketing for Calibre physical verification at Mentor, a Siemens Business, looks at the growing compute requirements at 7, 5 and 3nm, why the cloud looks increasingly attractive from a security and capacity standpoint, and how the cloud as well as new lithography will affect the cost and complexity of developing new chips. » read more

Extreme Quality Semiconductor Manufacturing


By Ben Tsai and Cathy Perry Sullivan Across the full range of semiconductor device types and design nodes, there is a drive to produce chips with significantly higher quality. Automotive, IoT and other industrial applications require chips that achieve very high reliability over a long period of time, and some of these chips must maintain reliable performance while operating in an environmen... » read more

AI And Big Data Set To Reinvent Semiconductor Industry


The recent IEEE International Electron Devices Meeting (IEDM) reaffirmed that the semiconductor industry is in a period of reinvention as we grapple with the challenges and opportunities promised by the Internet of Things (IoT), Big Data and AI. That such change is underway was made evident by a panel I was honored to moderate titled, “The Future of Logic: EUV is Here, Now What?” Joining... » read more

Finding Defects In EUV Masks


Extreme ultraviolet (EUV) lithography is finally in production at advanced nodes, but there are still several challenges with the technology, such as EUV mask defects. Defects are unwanted deviations in chips, which can impact yield and performance. They can crop up during the chip manufacturing process, including the production of a mask or photomask, sometimes called a reticle. Fortunately... » read more
