About Semiconductors & Photonics in Canada
This sector covers integrated circuits and chip design, photonic integrated circuits, lasers and optical components, compound semiconductors and MEMS, packaging, and the process and metrology technology used to make them.
Photonics is the larger part of it in this dataset, and it connects directly to Quantum and to Cloud & Digital Infrastructure — the same optical components turn up in a quantum computer and in a data-centre interconnect.
How this list is built
Every Semiconductors & Photonics record here is hand-checked, and the 398 claims across them each link to a page you can open. Where a figure is not published, the field is left blank rather than estimated.
