  • Patent number: 8252659
    Abstract: The present disclosure is related to method for producing a semiconductor device comprising the steps of: providing a semiconductor substrate (1), comprising active components on the surface of said substrate, depositing a top layer (2) of dielectric material on the surface of said substrate or on other dielectric layers present on said surface, etching at least one first opening (7) at least through said top layer, filling said opening(s) at least with a first conductive material (8), and performing a first CMP step, to form said first conductive structures (3,26), etching at least one second opening (13) at least through said top layer, filling said opening(s) at least with a second conductive material (10), and performing a second CMP step, to form said second conductive structures (4,24), wherein the method comprises the step of depositing a common CMP stopping layer (5,25) on said dielectric top layer, before the steps of etching and filling said first opening(s), so that said same CMP stopping layer is

  • Patent number: 7611986
    Abstract: A method for patterning a dual damascene structure in a semiconductor substrate is disclosed. The patterning is a metal hardmask based pattering eliminating at least resist poisoning and further avoiding or at least minimizing low-k damage. The method can be used as a full-via-first patterning method or a partial-via-first patterning method.

  • Patent number: 6136619
    Abstract: A method for measuring resistance changes is described to study electromigration induced failures in conductive patterns. This method can provide a basis for lifetime predictions based on low value failure criteria, i.e. small resistance changes in the conductive patterns in a limited period of time. Two essentially identical so-called test and reference structures are placed close to each other on the same substrate and submitted to at least one sequence of a stress period and a measurement period. During a stress period, a DC current with a high current density is applied to the test structure thereby enhancing electromigration, while substantially simultaneous an AC current is applied to the reference structure leading to the same amount of power dissipation in said reference structure as the amount of power dissipation in said test structure, introduced by said DC stress current.
