Scientists smash record in stacking semiconductor transistors for large-area electronics

Breakthrough in Semiconductor Transistor Stacking

Researchers at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia have achieved a record in microchip design by creating the first six-stack hybrid CMOS (complementary metal-oxide semiconductor) for large-area electronics.

This feat surpasses the previous limit of two stacks, setting a new benchmark in integration density and efficiency. The research, published in Nature Electronics, opens up possibilities for electronic miniaturization and performance.

CMOS microchips are widely used in various electronics, including phones, televisions, satellites, and medical devices. Hybrid CMOS microchips, in particular, hold greater promise for large-area electronics compared to conventional silicon chips.

Electronic miniaturization is crucial for applications such as flexible electronics, smart health, and the Internet of Things. However, current design approaches are reaching their limits, making this breakthrough a significant step forward.

The team's research appears in Nature Electronics, marking a new milestone in microchip design.

Author's summary: KAUST researchers set a record in microchip design with six-stack hybrid CMOS.
