Definition: Ultra-thin layers of silicon used in advanced semiconductor manufacturing for stacking transistors vertically.
Explanation
Silicon films are ultra-thin sheets of silicon, typically around 10 nanometers thick, used in semiconductor fabrication to enable three-dimensional stacking of transistors. These films can be transferred onto existing chip structures at low temperatures, preserving the integrity of previously fabricated circuitry. This technology allows for higher transistor density and improved performance without the thermal damage associated with traditional high-temperature processing.
Example
Researchers use silicon films peeled from a substrate and transferred onto a chip using a rolling process at temperatures below 200°C, enabling multi-layer silicon transistor architectures without damaging underlying circuits.
