About Onto Innovation
Onto Innovation makes inspection, metrology and lithography tools plus analytics software for semiconductor factories. Metrology means measuring features on a wafer, such as film thickness and pattern dimensions, to keep production on target. Its range covers wafer and panel inspection, optical measurement, and steppers for advanced packaging, the process that joins several chips into one module. It is headquartered in Wilmington, Massachusetts. It supplies equipment to chipmakers and does not design processors, so it serves compute hardware indirectly.
Onto Innovation was founded in 2019 and is based in Wilmington, MA, United States. It is listed under Custom Silicon. Its shares trade as ONTO on NYSE.

Custom Silicon
Custom silicon means a company designs its own chips for its own products or data centers instead of buying standard parts. The chip is made by a foundry such as TSMC, but the design belongs to the customer.
