Intrinsic Float Zone Silicon offers the highest purity possible, with electrical carriers below detection limits and exceptionally high minority carrier lifetimes. Its combination of excellent bulk properties and advanced wafer-surface processing makes Topsil Intrinsic Float Zone Silicon an ideal substrate for advanced quantum technologies, where a minimum of two-level system defects is essential for achieving long coherence times and consistent qubit performance. Additionally, it is ideal for achieving lossless radio-frequency systems.
Topsil Intrinsic Float Zone Silicon is characterized by unique material properties:
NB: The proven performance of Topsil INTRINSIC Float Zone Silicon for quantum platforms is highlighted in a NATURE magazine publication, reporting record high coherence times for superconducting qubits (Bland, M.P., Bahrami, F., Martinez, J.G.C. et al., Nature 647, 343–348 (2025)).
