  • Publication number: 20210111182
    Abstract: Some embodiments relate to an integrated chip that includes a first source/drain region and a second source/drain region disposed in a substrate. A plane that is substantially perpendicular to an upper surface of the substrate traverses the first source/drain region and the second source/drain region. Agate electrode extends over a channel region in the substrate between the first source/drain region and the second source/drain region. The gate electrode is separated from the channel region by way of a charge trapping dielectric structure. The charge trapping dielectric structure includes a tunnel dielectric layer, a charge trapping dielectric layer over the tunnel dielectric layer, and a blocking dielectric layer over the charge trapping dielectric layer. The channel region has a channel width measured perpendicularly to the plane, and the tunnel dielectric layer has different thicknesses at different respective points along the channel width.

  • Patent number: 10963868
    Abstract: Technology is disclosed for transferring money anonymously between a sender and a recipient by use of a token. In some embodiments, the disclosed technology involves communication between a mobile payment application (“App”) and a payment service system (PSS). Upon the recipient's request, the App, installed on the recipient's device, generates the token, and provides the token to both the recipient and the PSS. The PSS receives both the token and the recipient's identification information from the App, associates the token with the identification information, and stores such association. The recipient, on the other hand, transfers the token to the sender, who forwards it to the PSS to request a money transfer. The PSS receives the token and identifies the recipient's identification information based on the previously stored association with the token. With the identification information, the PSS determines the recipient's financial account to execute the money transfer.

  • Patent number: 10937795
    Abstract: Various embodiments of the present application are directed towards a method to integrate NVM devices with a logic or BCD device. In some embodiments, an isolation structure is formed in a semiconductor substrate. The isolation structure demarcates a memory region of the semiconductor substrate, and further demarcates a peripheral region of the semiconductor substrate. The peripheral region may, for example, correspond to BCD device or a logic device. A doped well is formed in the peripheral region. A dielectric seal layer is formed covering the memory and peripheral regions, and further covering the doped well. The dielectric seal layer is removed from the memory region, but not the peripheral region. A memory cell structure is formed on the memory region using a thermal oxidation process. The dielectric seal layer is removed from the peripheral region, and a peripheral device structure including a gate electrode is formed on the peripheral region.

  • Patent number: 10879257
    Abstract: The present disclosure relates to a method of forming an embedded flash memory cell that provides for improved performance by providing for a tunnel dielectric layer having a relatively uniform thickness, and an associated apparatus. The method is performed by forming a charge trapping dielectric structure over a logic region, a control gate region, and a select gate region within a substrate. A first charge trapping dielectric etching process is performed to form an opening in the charge trapping dielectric structure over the logic region, and a thermal gate dielectric layer is formed within the opening. A second charge trapping dielectric etching process is performed to remove the charge trapping dielectric structure over the select gate region. Gate electrodes are formed over the thermal gate dielectric layer and the charge trapping dielectric structure remaining after the second charge trapping dielectric etching process.
