IBM and Samsung Electronics claimed a breakthrough in semiconductor design based on a new IBM’s architecture touted as enabling an 85-percent reduction in power consumption.
The partners said the Vertical Transport Field-Effect Transistors (VTFET) scheme offers greater power efficiency over FinFET designs, potentially extending Moore’s Law scaling beyond current two-dimensional nanosheet thresholds.
FinFETs are generally designed to lie flat atop a wafer to allow electric currents to flow horizontally. Compared to a planar transistor, FinFETs help reduce power leakage while providing greater device density.
Unlike FinFETs, the companies said VTFETs are situated perpendicular to a chip substrate, allowing electric currents to flow vertically. The companies claim the design could, for example, extend smartphone battery life beyond a week without requiring a charge, according to IBM’s blog post.
