TAIPEI (Taiwan News) — Taiwan's GlobalWafers Co. is expanding further into advanced materials, extending its expertise in ultra-pure silicon to emerging applications in quantum technology, CTEE reported Wednesday.

Silicon is the most widely used semiconductor material, and its purity plays a decisive role in chip yields and process stability, according to TechNews. These material requirements are even more stringent in quantum technologies, where performance is highly sensitive to microscopic defects.

GlobalWafers’ high-purity silicon manufacturing capabilities have now been applied to quantum research.

A recent study using ultra-pure silicon produced by Topsil, a subsidiary of GlobalWafers, was published in the scientific journal Nature in November. The research showed that when the material was used in superconducting quantum bits, or qubits, system stability improved significantly, allowing quantum devices to operate reliably for longer periods.

GlobalWafers Chair Doris Hsu (徐秀蘭) said the company is working closely with leading research institutions and technology firms to convert advances in quantum research into practical and commercially viable applications. She added that demand related to quantum technologies continues to grow steadily.

Quantum devices are highly sensitive, and even minimal material imperfections can disrupt performance. Ensuring consistent material quality is therefore one of the main challenges in scaling up quantum systems and improving their reliability.

Demand for ultra-pure silicon continues to rise across advanced technology sectors, underscoring its role in both digital and energy transitions. Its electrical and structural properties make it essential for applications ranging from semiconductor manufacturing and solar energy systems to quantum technologies, according to SFA Oxford.
