Abstract: An advanced security method for verifying that integrated circuit patterns being processed into one or more layers provided to a wafer are trusted patterns and that the wafer being used during processing is a trusted wafer is provided. The method includes separate steps of pattern verification and wafer verification. Notably, the method includes first verifying that a pattern printed on a wafer matches a pattern of a trusted reference. Next, a peak and valley profile present at a specific location on a backside surface of the wafer is measured. The method further includes second verify that the measured peak and valley profile matches an original peak and valley profile measured at the same location on the backside surface of the wafer.

Abstract: Customers are able to create campaigns that consist of either polls, ads, or coupons and will receive direct feedback from the consumer(s) they inquire with. Campaigns are delivered by a software platform where the campaign is delivered to participating consumers without the consumers having to physically travel somewhere. Consumers will receive push notifications on their smartphones through a mobile app letting them know that they have an inquiry. The consumers will then read the poll/ad/coupon, provide their feedback, and get paid. Feedback is provided in a couple different ways, depending on the type of campaign. In polls and ads, feedback comes in the form of a choice of either yes or no answers or an answer from a multiple choice question. With coupons, members provide their feedback by choosing to either save the coupon to their coupon wallet in the mobile app, or discard it if they are not interested.
