King Abdullah University of Science and Technology (KAUST; Saudi Arabia) researchers have set a record in microchip design, achieving the first six-stack hybrid CMOS (complementary metal-oxide semiconductor) for large-area electronics. With no other reported hybrid CMOS exceeding two stacks, the feat marks a new benchmark in integration density and efficiency, opening possibilities in electronic miniaturization and performance.

A paper detailing the team’s research appears in Nature Electronics.

Among microchip technologies, CMOS microchips are found in nearly all electronics, from phones and televisions to satellites and medical devices. Compared with conventional silicon chips, hybrid CMOS microchips hold greater promise for large-area electronics...

Emerging AI applications, like chatbots that generate natural human language, demand denser, more powerful computer chips. But semiconductor chips are traditionally made with bulk materials, which are boxy 3D structures, so stacking multiple layers of transistors to create denser integrations is very difficult.

However, semiconductor transistors made from ultrathin 2D materials, each only about three atoms in thickness, could be stacked up to create more powerful chips...
