The Sub-2nm Paradox


Key Takeaways: Process variation and physics are changing semiconductor design, manufacturing, and economics at 2nm and below. Even though new manufacturing processes are being introduced, it's taking longer for them to mature. The focus for many chip designs is faster data movement and more efficient computing, rather than just relying on more transistors per mm2. At 2nm an... » read more

Precision In Depth: Extraction Workflows For CFETs And Buried Power Rails


By Karen Chow, Sheetal Veronica, and Kunjesh Agashiwala In the heart of Manhattan, where land is scarce but demand is infinite, architects had to rethink the city grid. Instead of sprawling outward, they built upward with skyscrapers and carved subways below ground, inventing a “3D” city. Today’s chip designers face a similar dilemma: the two-dimensional plane of planar scaling is near... » read more

Extraction Challenges of CFET and Backside Power Delivery


The integration of complementary field-effect transistors (CFETs) and buried power rails (BPRs) is central to advancing semiconductor scaling for nodes at 3nm and below. CFETs achieve unprecedented device density by vertically stacking n-type and p-type transistors, while BPRs embed the power network within the silicon substrate to boost efficiency and minimize area usage. These advances drive ... » read more

2D Semiconductors Inch Forward


Key Takeaways: Diffusing oxygen into 2D materials can improve adhesion properties. Channel-last processes can preserve most of the traditional gate-all-around process flow. Dual-gate MoS2 FETs with graphene contacts take advantage of layer transfer methods. Transition metal dichalcogenides (TMDs) have come a long way since exfoliated flakes were the state of the art, but the... » read more

CMOS 2.0: Layered Logic For The Post-Nanosheet Era


The semiconductor industry has relied on a simple equation for more than five decades — shrink the transistor, pack more onto every wafer, and watch performance soar as costs plummet. While each new node delivered predictable gains in speed, power efficiency, and density, that formula is rapidly running out of steam. As transistors approach single-digit nanometer processes, manufacturing c... » read more
