  • Publication number: 20140070000
    Abstract: The system provides a two device solution for transaction processing, a merchant facing device (MFD) and a cardholder (customer) facing device CFD. What this means is that one device always faces the checkout representative of the merchant (the merchant facing device) and the other faces the consumer (the cardholder facing device). The CFD includes a payment/card reader (such as a swipe style reader, a near field communication (NFC) or RFID reader, or some other contactless means) and a numeric key pad (i.e. PIN pad) where the consumer can, when required, allow the card to be read (e.g. by swipe, insert, or wave the card) and enter an authorization PIN (personal identification number).

  • Publication number: 20040173918
    Abstract: The present invention relates to a memory array comprising a substrate and a plurality of bitlines having contacts and a plurality of wordlines intersecting the bitlines. A protective spacer is used to separate the bitline contacts from the wordlines adjacent to the bitline contacts to prevent damage caused during the formation of the bitline contacts. The present invention also relates to a method of forming the memory array.

  • Patent number: 6750066
    Abstract: A semiconductor device which includes a precision high-K dielectric and formed on a semiconductor substrate and a method of forming the same. The semiconductor device includes at least one dielectric layer having a dielectric constant greater than SiO2. The at least one dielectric layer is deposited by atomic layer deposition (ALD). The ALD deposited layer has precise uniformity, thickness and abrupt atomic interfaces.
