Semiconductor Engineering sat down to discuss extreme ultraviolet (EUV) lithography and photomask technologies with Emily Gallagher, principal member of the technical staff at Imec; Harry Levinson, principal at HJL Lithography; Chris Spence, vice president of advanced technology development at ASML; Banqiu Wu, senior director of process development at Applied Materials; and Aki Fujimura, chief ... » read more

Electric Cars Gain Traction, But Challenges Remain

By Mark LaPedus - 22 Apr, 2019 - Comments: 4

Battery-powered electric vehicles are expected to reach a milestone in terms of shipments in 2019, but the technology faces several significant hurdles to gain wider adoption in the market. Limited driving range, high costs, battery issues, and a spotty charging infrastructure are the main challenges for battery electric vehicles (BEVs). In addition, there are issues with various power semic... » read more

Lithography Options For Next-Gen Devices

By Mark LaPedus - 18 Apr, 2019 - Comments: 2

Chipmakers are ramping up extreme ultraviolet (EUV) lithography for advanced logic at 7nm and/or 5nm, but EUV isn’t the only lithographic option on the table. For some time, the industry has been working on an assortment of other next-generation lithography technologies, including a new version of EUV. Each technology is different and aimed at different applications. Some are here today, w... » read more

Finding The Source Of EUV Stochastic Effects

By Katherine Derbyshire - 15 Apr, 2019 - Comments: 7

The next phase of EUV development has begun—making EUV more predictable and potentially more mainstream—and it's looking to be every bit as difficult and ambitious as other developments in advanced lithography. In the early days of EUV development, supporters of the technology argued that it was “still based on photons,” as opposed to alternatives like electron beam lithography. Whil... » read more

Week In Review: Manufacturing, Test

Materials Wesfarmers, an Australian diversified firm, has made an unsolicited bid to acquire Lynas, one of the world’s largest suppliers of rare earths outside of China. Rare earths are chemical elements found in the Earth’s crust. They are used in cars, consumer electronics, computers, communications, clean energy and defense systems. The big market for rare earths is magnets. In semicond... » read more

Single Vs. Multi-Patterning EUV

By Mark LaPedus - 25 Mar, 2019 - Comments: 5

Extreme ultraviolet (EUV) lithography finally is moving into production, but foundry customers now must decide whether to implement their designs using EUV-based single patterning at 7nm, or whether to wait and instead deploy EUV multiple patterning at 5nm. Each patterning scheme has unique challenges, making that decision more difficult than it might appear. Targeted for 7nm, single pattern... » read more

Virtual Fabrication And Advanced Process Control Improve Yield For SAQP Process Assessment With 16nm Half-Pitch

By Coventor - 25 Mar, 2019 - Comments: 0

This paper uses Virtual Fabrication to assess the Imec 7nm node (iN7) Self-Aligned Quadruple Patterning (SAQP) integration scheme for the 16nm half-pitch Metal 2 line formation. We first present the technical challenge of obtaining defect-free M2 lines with SAQP, and then provide a solution to achieve a » read more

EUV Arrives, But More Issues Ahead

By Katherine Derbyshire - 21 Mar, 2019 - Comments: 5

EUV has arrived. After decades of development and billions of dollars of investment, EUV lithography is taking center stage at the world’s leading fabs. More than 20 years after ASML's extreme ultraviolet lithography research program began, and nearly a decade after its first pre-production exposure tools, the company expects to deliver 30 EUV exposure systems in 2019. That is nearly doubl... » read more

Nanomesh material could find use in sustainable applications Imec collaborated with KU Leuven to develop a nanomesh material made of a 3D structure with nanowires. This material could prove to make batteries more energy-efficient, while also improving catalytic converters and fuel cells, and making hydrogen production easier. The research team is touting the 3D nanometer-scale metal grid st... » read more
