  • Publication number: 20150130064
    Abstract: Processes for improving adhesion of films to semiconductor wafers and a semiconductor structure are provided. By implementing the processes of the invention, it is possible to significantly suppress defect creation, e.g., decrease particle generation, during wafer fabrication processes. More specifically, the processes described significantly reduce flaking of a TaN film from edges or extreme edges (bevel) of the wafer by effectively increasing the adhesion properties of the TaN film on the wafer. The method increasing a mol percent of nitride with respect to a total tantalum plus nitride to 25% or greater during a barrier layer fabrication process.

  • Patent number: 8878315
    Abstract: A MEMS structure and methods of manufacture. The method includes forming a sacrificial metal layer at a same level as a wiring layer, in a first dielectric material. The method further includes forming a metal switch at a same level as another wiring layer, in a second dielectric material. The method further includes providing at least one vent to expose the sacrificial metal layer. The method further includes removing the sacrificial metal layer to form a planar cavity, suspending the metal switch. The method further includes capping the at least one vent to hermetically seal the planar cavity.

  • Publication number: 20140035169
    Abstract: A structure and method for fabricating the structure that provides a metal wire having a first height at an upper surface. An insulating material surrounding said metal wire is etched to a second height below said first height of said upper surface. The metal wire from said upper surface, after etching said insulating material, is planarized to remove sufficient material from a lateral edge portion of said metal wire such that a height of said lateral edge portion is equivalent to said second height of said insulating material surrounding said metal wire.

  • Patent number: 8586466
    Abstract: Electrical fuses and methods for forming an electrical fuse. The electrical fuse includes a current shunt formed by patterning a first layer comprised of a first conductive material and disposed on a top surface of a dielectric layer. A layer stack is formed on the current shunt and the top surface of the dielectric layer surrounding the current shunt. The layer stack includes a second layer comprised of a second conductive material and a third layer comprised of a third conductive material. The layer stack may be patterned to define a fuse link as a first portion of the layer stack directly contacting the top surface of the dielectric layer and a terminal as a second portion separated from the top surface of the dielectric layer by the current shunt.
