Curvilinear Photomasks Can Be Made Today
By Jan Willis - 21 Apr, 2022 - Comments: 0

Multi-beam mask writers (MBMWs) and GPU-accelerated curvilinear ILT are enabling curvilinear photomasks to be made today. Despite the benefits of improved process windows, curvilinear photomask adoption is slow. Industry luminaries surveyed by the eBeam Initiative in 2021 ranked photomask inspection and infrastructure as the top barriers to adoption, as shown in figure 1. Yet only 4% say the b... » read more

Equipment Perspective At U.S. Senate Hearing On Chipmaking
By Tim Archer - 21 Apr, 2022 - Comments: 0

In March, Lam Research President and CEO Tim Archer testified before the United States Senate Committee on Commerce, Science, and Transportation. The hearing examined a variety of issues including the correlation between American competitiveness and semiconductors, the impact of vulnerabilities in semiconductor supply chains and the importance of CHIPS legislation within the U.S. Innovation a... » read more

5 Traits For Healthy Competition
By Tom Brown - 21 Apr, 2022 - Comments: 0

Competition encourages continuous improvement. Therefore, to enable growth, surround yourself with others who aspire to be better. This fundamental concept is most notably quoted in Proverbs 27:17, “iron sharpens iron,” interpreted as when both people are committed to growth, they recognize challenges as opportunities, not obstacles. Competitive people are found everywhere. The competiti... » read more

Wirebond IC Substrates: Challenges Ahead
By Prasad Dhond - 17 Mar, 2022 - Comments: 0

Substrate suppliers are slashing capacity allocated to wirebond IC substrates. We hear about "limited tenting capacity," "no support for EBS designs," and requests for "conversion to etchback" designs. What does all this mean? Let's start with "Line" and "Space." "Line" is the width of a trace on a substrate and "Space" is the distance between the two traces. For wirebond packages such a... » read more

Accelerating Semiconductor Process Development Using Virtual Design Of Experiments
By Qingpeng Wang - 17 Mar, 2022 - Comments: 0

Design of Experiments (DOE) are a powerful concept in semiconductor engineering research and development. DOEs are sets of experiments used to explore the sensitivity of experimental variables and their effect on final device performance. A well-designed DOE can help an engineer achieve a targeted semiconductor device performance using a limited number of experimental wafer runs. However, in se... » read more

Precision Selective Etch And The Path To 3D
By Vahid Vahedi - 17 Mar, 2022 - Comments: 0

Scaling (the shrinking of the tiny devices in chips such as transistors and memory cells) has never been easy, but making the next generation of advanced logic and memory devices a reality requires creating new structures at the atomic scale. When working with dimensions this small, there is little room for variation. Compounding the problem is a need to remove material isotropically, or, un... » read more

The Great Resignation And The Microelectronics Industry: Retaining A Skilled Workforce
By Michelle Williams-Vaden - 17 Mar, 2022 - Comments: 0

"Now hiring" signs are replacing masks and bottles of hand sanitizer as the ubiquitous markers of COVID-19, as the Great Resignation continues, and the Omicron surge ebbs. Everywhere – at fast food restaurants, at top tech companies – there are job openings, offering cash just for showing up at an interview, or up to $100,000 in sign-on bonuses. Consumers across all industries are bein... » read more
