Share Repurchase Program [Abstract] |
Share Repurchase [Text Block] | In February 2024, the Onto Innovation Board of Directors approved a new share repurchase authorization, which allows the Company to repurchase up to $200 million worth of shares of its common stock. Repurchases may be made through both public market and private transactions from time to time. Any amount paid to repurchase the shares in excess of par value, including transaction costs, would be recorded directly as a decrease to additional paid-in capital and accumulated earnings. During the three and six months ended June 28, 2025, 0 and 492 thousand shares of the Company’s common stock were repurchased under the share repurchase authorization, respectively. At June 28, 2025, there was $99.9 million available for future share repurchases under this share repurchase authorization.
