Single Vs. Multi-Patterning Advancements For EUV
By Gregory Haley - 20 Jun, 2024 - Comments: 0

As semiconductor devices become more complex, so do the methods for patterning them. Ever-smaller features at each new node require continuous advancements in photolithography techniques and technologies. While the basic lithography process hasn’t changed since the founding of the industry — exposing light through a reticle onto a prepared silicon wafer — the techniques and technology ... » read more

Virtual Exploration Of Novel Vertical DRAM Architectures
By Taeyon (TY) Oh - 20 Jun, 2024 - Comments: 0

In this article, we demonstrate a pathfinding technique for a novel Vertical DRAM technology. First, we identify important process parameters (defined by current semiconductor production equipment capabilities) that strongly impact yield. By using a virtual model, we then perform experimental optimization of the Vertical DRAM device across specific target ranges, to help predict and improve the... » read more

Understanding CFETs, A Next Generation Transistor Architecture
By Sam Sarkar - 23 May, 2024 - Comments: 0

Computing power has experienced exponential growth over the last 70 years. This has largely been achieved through transistor scaling. Due to a continuous reduction in the size of transistors, engineers have been able to pack more and more of them onto a single chip [1]. This has led to faster, more powerful, and more energy-efficient devices. Improvements in fabrication processes and materials,... » read more

Reducing Risk In The Semiconductor Supply Chain
By Laura Peters - 23 May, 2024 - Comments: 0

Companies that were hit with chip shortages during the pandemic are changing their strategies to prevent future problems, deploying a combination of supply chain mapping, second sourcing, and digital transformation. Those shortages caused a $200 billion loss for automotive manufacturers, and the disruptions were far more widespread, in many cases lasting for years. Companies of all sorts wer... » read more

Using Predictive Maintenance To Boost IC Manufacturing Efficiency
By Laura Peters - 14 May, 2024 - Comments: 0

Predicting exactly how and when a process tool is going to fail is a complex task, but it's getting a tad easier with the rollout of smart sensors, standard interfaces, and advanced data analytics. The potential benefits of predictive maintenance are enormous. Higher tool uptime correlates with greater fab efficiency and lower operating costs, so engineers are pursuing multiple routes to boo... » read more
