  • Publication number: 20240095899
    Abstract: The present disclosure includes edge defect detection via image analytics. A method includes identifying an image of an edge of a susceptor pocket formed by a susceptor of a substrate processing system. The method further includes predicting, based on the image, whether property values of the edge of the susceptor meet threshold values. The method further includes, responsive to the property values of the edge meeting threshold values, causing performance of a corrective action associated with the susceptor.

  • Publication number: 20240087135
    Abstract: A method includes identifying an image of a substrate processing equipment part that forms a plurality of holes. The method further includes determining, by a processing device based on the image, a corresponding neighboring angular distance of each of the plurality of holes and a corresponding area of each of the plurality of holes. The method further includes identifying, by the processing device, a first subset of the plurality of holes that are at least partially clogged based on at least one of the corresponding neighboring angular distance or the corresponding area of each of the plurality of holes. A corrective action associated with the substrate processing equipment part is to be performed based on the first subset of the plurality of holes that are at least partially clogged.

  • Publication number: 20140067678
    Abstract: A method for resolving disputes arising from failed and incomplete payment transactions conducted over a mobile communication infrastructure, comprising generating, by a central processing server, a key and a dispute code using the key and a payment transaction status; receiving, by a payer user device, the dispute code; receiving, by a payee user device, the key; updating, by the central processing server, the dispute code with updated payment transaction status when the payment transaction is completed; receiving, by the payer user device, the updated dispute code; entering into the payee user device the updated dispute code received by the payer user device; generating, by the payee user device, a verifying dispute code using the key and one of the one or more preset status codes; and verifying, by the payee user device, the updated dispute code by comparing the updated dispute code to the verifying dispute code generated.
