Cookie Policy

Last updated November 1, 2018

This Cookie Policy (“Cookie Policy”) applies to the cookies on all the websites owned or operated by KLA Corporation and its subsidiaries (“KLA” or the “Company”) (including,, and, (the “Site”).

The Site uses a number of different cookies. This Cookie Policy explains the following:

  • What are cookies?
  • Cookies we use and why we use them
  • Your right to refuse cookies


Cookies are small files which are downloaded to your device when you visit a website. The cookie then sends information back to the originating website on each subsequent visit, or to another website that recognizes that cookie. Cookies are useful because they allow a website to recognize a user’s device. You can find more information about cookies at: and

Cookies do lots of different jobs, like letting you navigate between pages efficiently, remembering your preferences, and generally improving the user experience.


Cookies are often categorized by function.

Essential Cookies

These are cookies that are strictly necessary for the functioning of the website or for performing services that an individual user has requested. Some examples of functions performed by essential cookies are cookies that remember previous actions (e.g., entered text) when navigating back to a page in the same session.

We use Essential Cookies on our website to track and store information from potential candidates who visit the site to view open positions. Cookies create a personalized experience for visitors such as pre-populate the location search based on the visitor’s IP location. Information collected will be stored in an anonymous profile until the visitor self identifies themselves at which point a profile is created for the candidate.

Analytical Cookies

These cookies collect information about how visitors use a website, for instance which pages visitors go to most often, and if they get error messages from web pages. Analytical cookies don’t collect information that identifies a visitor. All information that analytical cookies collect is aggregated and therefore anonymous. These cookies are used only to improve how a website functions.

Many websites use targeting/advertising cookies; our Site does not.

Cookies can also be categorized by how long they remain on your device. There are two broad categories of duration:

  1. Persistent cookies

    Persistent cookies remain on your device until deleted manually or automatically.

  2. Session cookies

    Session cookies remain on your device until you close your browser when they are automatically deleted.

We use both persistent and session cookies. The persistent cookies remain active for up to 2 years.

Finally, cookies are either first-party or third-party cookies:

  1. First-Party Cookies

    First-party cookies are placed by the website operator. For example, first-party cookies on our Site are cookies placed by KLA.

  2. Third-Party Cookies

    Third-party cookies are cookies placed by a third party. For example, we use a third-party service provider called Google Analytics to analyze how users use our Site. Google Analytics collects de-identified information about usage, such as how long users stop on a web page and route they took through the Site. Google Analytics places cookies to collect this usage information.

KLA uses both first-party and third-party cookies on our Site.

Web Beacons:
The Company includes small graphic images or other web programming code, called web beacons (also known as “pixel tags,” “web bugs” or “clear GIFs”) on the Websites. The web beacons are minute graphics with a unique identifier. They are used to track the online movements on Web users. In contrast to cookies, which are stored on a user’s device, web beacons are embedded invisibly on Web pages and are about the size of the period at the end of this sentence. Web beacons may work with cookies to collect information about users’ movements from web page to web page.

Information collected:
Our cookies collect several types of information, including information about your usage of our Site, device identifier, screen resolution, browser identifier, city, state, region, language, service provider, link from which a user comes to the Site, links on the Site, Site pages visited, and length of time on a Site page, and your IP address. An IP address is the number assigned to your device, for example your laptop or mobile phone, when your device accesses the internet. Your device may have a static IP address, which means that your device always has the same IP address or it may have a dynamic IP address, which means that the IP address changes each time the device accesses the internet.

The Company does not link the information collected through cookies with individually identifiable information (personal data) collected through the Site, for example, if you enter your name into a form on the Site. To the extent information collected through cookies is individually identifiable, we treat it as personal data in accordance with our Privacy Policy.

Location of information processing:
The information collected by our cookies is processed in servers located in the United States.

Sharing information:

The information collected by our cookies is only shared in aggregate form with our service providers, including the following:
