Semiconductors

Semiconductor manufacturing techniques, such as those used by GlobalFoundries, are being leveraged to fabricate silicon-based quantum chips. These chips integrate arrays of quantum dots (qubits) and control electronics on a single chip using established high-volume semiconductor processes. This approach enables rapid, large-scale characterization and scalability, bridging the gap between quantum research and industrial-scale production.

GlobalFoundries' 22FDX platform offers power-efficient edge processing, system-on-chip integration, and supports cryogenic tuning and control at temperatures as low as 1 Kelvin. It provides a back gate bias capability that enhances readout and control operations for quantum devices, making it significantly advantageous compared to bulk silicon solutions for scalable quantum processor manufacturing.

2D semiconductors are materials that are only a few atoms thick, offering advantages like higher energy efficiency and integration density compared to traditional bulk materials. They can be stacked to create denser, more powerful chips without the limitations of traditional silicon-based transistors[2][3].

CDimension's method allows for the direct growth of ultra-thin 2D materials onto finished silicon wafers without damaging the underlying circuitry. This approach enables dense vertical stacking, improves energy efficiency, and increases integration density, potentially revolutionizing chip design by overcoming traditional manufacturing hurdles[1][3].
