  • Patent number: 11405389
    Abstract: A system includes first electronic devices and a digital signature carrier. Each of the first electronic devices has a network identifier distinct from another. The digital signature carrier is configured for recording a connective information list. The connective information list includes the network identifiers of all of the first electronic devices. A second electronic device includes a digital signature reader. The second electronic device is configured to read the digital signature carrier by the digital signature reader, extract the connective information list comprising the network identifiers and pair the second electronic device with each of the first electronic devices according to the network identifiers.

  • Publication number: 20220149181
    Abstract: A method includes forming a first fin and a second fin over a substrate. The method includes forming a first dummy gate structure that straddles the first fin and the second fin. The first dummy gate structure includes a first dummy gate dielectric and a first dummy gate disposed over the first dummy gate dielectric. The method includes replacing a portion of the first dummy gate with a gate isolation structure. The portion of the first dummy gate is disposed over the second fin. The method includes removing the first dummy gate. The method includes removing a first portion of the first dummy gate dielectric around the first fin, while leaving a second portion of the first dummy gate dielectric around the second fin intact. The method includes forming a gate feature straddling the first fin and the second fin, wherein the gate isolation structure intersects the gate feature.

  • Publication number: 20130270120
    Abstract: A system and process for reducing cosmetic defects such as black lines, and otherwise improving the final cosmetic appearance of anodized parts is disclosed. The process can include degreasing an aluminum or other metal part in a neutral to low alkaline solution having a mild detergent, chemically polishing the metal part with a specialized solution having one or more additives at an increased temperature for a reduced amount of time, and anodizing the metal part at a reduced voltage and for a reduced amount of time. An activating step can also be performed as part of the overall process. Tap water rinse, deionized water rinse, desmut, seal and bake procedures can also be performed on the metal part.

  • Patent number: 8169043
    Abstract: An optical sensor package structure includes a substrate, a metal plate, an optical sensing chip, a plurality of bonding wires and a lens module. The substrate includes a top surface, a bottom surface and a hole penetrating the top surface and the bottom surface. The metal plate covers the hole from the bottom surface of the substrate. The optical sensing chip is received in the hole and mounted on the metal plate. The bonding wires interconnect the optical sensing chip and the top surface of substrate. The lens module is covering on the hole and mounting on the top surface of the substrate to enclose the optical sensing chip and the bonding wires. Because the optical sensing chip is received in the hole of the substrate, the height of the optical sensor package structure can be reduced to adapt to a compact size electrical device.
