MTI provides California residents the privacy rights described in the table below pursuant to our obligations under the Privacy Laws. To exercise your privacy rights, or, if you are an authorized agent of another exercising privacy rights on behalf of someone else, you can submit a request by the following methods: 

  • Email: [email protected] 
  • Mail: Mattson Technology, Inc. 
    Attn: HR Department 
    47131 Bayside Parkway 
    Fremont, CA 94538 

Please respond to any follow-up inquiries we make, including in relation to the request verification process that we describe further below. 

RIGHT TO KNOW You have the right to request that we disclose to you the PI we collected about you in the 12-month period preceding your request. This right includes the right to request: (1) specific pieces of PI we have collected about you; (2) categories of PI we have collected about you; (3) categories of sources from which the PI was collected; (4) categories of PI that we sold or disclosed for a business purpose about you (if applicable); (5) categories of third parties to whom your PI was sold or disclosed for a business purpose (if applicable); and (6) the business or commercial purpose for collecting or, if applicable, selling your PI. 
RIGHT TO DELETE You have the right to request that we delete your PI that we have collected from you, with some exceptions. 
RIGHT TO CORRECT You have the right to correct inaccurate PI we maintain about you. 
RIGHT TO OPT OUT OF SALE You have the right to say no to the sale of your PI. The Privacy Laws defines “sell” to mean selling, renting, releasing, disclosing, disseminating, making available, transferring, or otherwise communicating orally, in writing, or by electronic or other means, a California resident’s PI to another business or a third party for monetary or other valuable consideration. MTI does not sell or share Employee PI with others for monetary or other valuable consideration.
RIGHT TO LIMIT PROCESSING OF SENSITIVE PI If we use or disclose Sensitive PI for purposes other than those allowed by the Privacy Laws and its regulations, the right to limit our use and disclosure. MTI does not use or disclose Sensitive PI for purposes other than those allowed by the Privacy Laws and its regulations.
RIGHT TO NON-DISCRIMINATON You have the right to non-discrimination for exercising your Privacy Laws rights. MTI will not and does not discriminate against you for exercising any of your Privacy Laws rights.


a) Request Verification Process: 

We will comply with your request upon verification of your identity and, where applicable, the identity of the California Employee on whose behalf your request is made. For requests to access categories of PI and for requests to delete or correct PI that is not sensitive and does not pose a risk of harm by unauthorized deletion or correction, we will verify your identity to a reasonable degree of certainty by verifying at least two data points that you previously provided to us and which we have determined to be reliable for the purpose of verifying identities. For requests to access specific pieces of PI or for requests to delete or correct PI that is sensitive and/or poses a risk of harm by unauthorized deletion or correction, we will verify your identity to a reasonably high degree of certainty by verifying at least three pieces of PI you previously provided to us and which we have determined to be reliable for the purpose of verifying identities. In addition, you must submit a signed declaration under penalty of perjury stating that you are the individual whose PI is being requested. If your request cannot be fulfilled due to an exception or our legal requirements, we will let you know. If we cannot verify you in respect of a certain requests, such as if you do not provide the requested information, we will still take certain action as required by the Privacy Laws. For example: 

  • If we cannot verify your deletion request, we will refer you to this Privacy Policy for a general description of our data practices. 
  • If we cannot verify your specific pieces request, we will treat it as a categories request. 

b) Agent Requests:

You may use an authorized agent to make a request for you via the above methods, subject to our verification of (i) the agent and (ii) the agent’s authority to submit requests on your behalf. Once your agent’s authority is confirmed, they may exercise rights on your behalf subject to the agency requirements of applicable law. 

c) Our Responses:

Some PI that we maintain is insufficiently specific for us to be able to associate it with an individual (e.g., clickstream data tied only to a pseudonymous browser ID). We do not include that PI in response to those requests. If we cannot comply with a request, we will explain the reasons in our response. We will make commercially reasonable efforts to identify PI that we maintain to respond to your requests. In some cases, particularly with voluminous and/or typically irrelevant data, we may suggest you receive the most recent or a summary of your PI and give you the opportunity to elect whether you want the entirety. We reserve the right to direct you to where you may access and copy responsive PI yourself. We will typically not charge a fee to fully respond to your requests; provided, however, that we may charge a reasonable fee, or refuse to act upon a request, if your request is excessive, repetitive, unfounded, or overly burdensome. If we determine that the request warrants a fee, or that we may refuse it, we will give you notice explaining why we made that decision. You will be provided a cost estimate and the opportunity to accept such fees before we will charge you for responding to your request.
