  • TOPOLOGICAL CRACK STOP (TCS) PASSIVATION LAYER
    Publication number: 20230108000
    Abstract: An integrated circuit structure comprises one or more first level interconnects (FLIs) embedded in an underfill (UF) over a substrate. An etch stop layer is over the FLIs. A passivation layer is over the etch stop layer and a plurality of vias are through the passivation layer. A plurality of contacts are on the passivation layer in contact with the vias to connect with the FLI. A plurality of topological crack stop (TCS) features are formed in the passivation layer and on a top surface of the etch stop layer.

  • Method and system for capture and use of intact vesicles on electrodeposited hydrophobically modified biopolymer films
    Patent number: 8858883
    Abstract: A biosensor comprising an electrically conductive substrate coated with a modified chitosan biopolymer that has been electrodeposited on the substrate, wherein said modified chitosan biopolymer comprises at least one vesicle binding molecule. The biosensor is manufactured by a method where a modified chitosan biopolymer is electrodeposited on a substrate. The method is also used to manufacture a modified chitosan biopolymer film by electrodeposition of the chitosan on the substrate and later removing the film from the substrate after electrodeposition. The resulting film can be used in bandages to treat various types of wounds. The biosensor can also be used to detect various analytes in samples.
