Supplier Conduct Principles

Onto Innovation recognizes a responsibility to hold ourselves and our suppliers, to high standards of behavior. This means complying with all applicable laws and regulations. We make a strong effort to work with suppliers to encourage sound practices and develop sound global markets. We strive to maintain an effective channel of communications with suppliers to set expectations. The following principles establish for our suppliers the minimum standards we expect from them as a condition of doing business with Onto Innovation. Compliance with these principles is a requirement for maintaining Onto Innovation supplier qualification. We will adhere to this policy in our selection process and will seek ongoing compliance by actively monitoring performance.

Forced or Involuntary Labor

Onto Innovation’s suppliers will not use forced or involuntary labor of any type (e.g., forced, bonded, indentured or involuntary prison labor); employment must be voluntary.

Child Labor

Onto Innovation’s suppliers will not use child labor. The term "child" refers to any person employed under the age of 15 (or 14 where the law of the country permits), or under the age for completing compulsory education, or under the minimum age for employment in the country, whichever is greatest. We support the use of legitimate workplace apprenticeship programs which comply with all laws and regulations applicable to such apprenticeship programs.

Wages and Benefits

Onto Innovation’s suppliers will, at a minimum, comply with all applicable wage and hour laws and regulations, including those relating to minimum wages, overtime hours, piece rates and other elements of compensation, and provide legally mandated benefits.

Working Hours

Onto Innovation’s suppliers will appropriately compensate for overtime worked. Workers shall not be required to work more than 60 hours per week, including overtime, except in extraordinary business circumstances with their consent. In countries where the maximum work week is less, that standard shall apply. Employees should be allowed at least one day off per seven-day week.


Onto Innovation’s suppliers will not discriminate in hiring and employment practices on grounds of race, religion, age, nationality, social or ethnic origin, sexual orientation, gender, gender identity or expression, marital status, pregnancy, political affiliation or disability.

Respect and Dignity

Onto Innovation’s suppliers will treat all employees with respect and will not use corporal punishment, threats of violence or other forms of physical coercion or harassment.

Confirming Compliance

Onto Innovation will confirm compliance with its global supply chain standards through:

The foregoing compliance confirmations, when performed, will be primarily executed by Onto Innovation employees but Onto Innovation reserves the right to engage third party monitors should the need arise. Any audit may be announced or unannounced as determined by Onto Innovation.

Currently Onto Innovation does not require our direct suppliers to certify that they comply with anti-slavery and human trafficking laws in the country or countries in which they do business.

While Onto Innovation has not trained its staff on this issue to date, in order to assure awareness and promote a culture of compliance in this area, Onto Innovation shall implement training for its employees and managers who have with direct responsibility for supply chain management on human trafficking and slavery within supply chains and methods to mitigate the related risk.

Should one of Onto Innovation’s direct product suppliers, employees, and contractors fail to comply with our Company’s requirements regarding the prevention of slavery and human trafficking, such party will receive written notice of the compliance issue and be subject to corrective action up to and including termination.
