Onto Innovation Inc.'s stock soared 5.03% during intraday trading on Friday, reflecting significant investor optimism.

The surge is primarily attributed to two key developments. First, the company announced a strategic capital and business alliance with Japan-based Rigaku Holdings, which includes a 27% equity investment. This partnership builds on their previous collaboration in hybrid metrology solutions and is expected to accelerate joint development projects. Second, Onto Innovation released preliminary first-quarter earnings that exceeded market expectations and provided an upward revision to its second-quarter guidance, prompting several investment banks to raise their target prices for the stock.

The positive momentum for Onto Innovation was also reflected in broader strength across the semiconductor equipment sector during the session.
