Patent number: 7413974Abstract: A metal structure (100) for a contact pad of a semiconductor, which has interconnecting traces of a first copper layer (102). The substrate is protected by an insulating overcoat (104). The first copper layer of first thickness and first crystallite size is selectively exposed by a window (110) in the insulating overcoat. A second copper layer (105) of second thickness covers conformably the exposed first copper layer. The second layer is deposited by an electroless process and consists of a transition zone, adjoining the first layer and having copper crystallites of a second size, and a main zone having crystallites of the first size. The distance a void can migrate from the second layer is smaller than the combined thicknesses of the first and second layers. A nickel layer (106) is on the second copper layer, and a noble metal layer (107) is on the nickel layer.Type: GrantFiled: August 4, 2005Date of Patent: August 19, 2008Assignee: Texas Instruments IncorporatedInventors: Howard R.

Patent number: 7413814Abstract: Getter multilayer structures are disclosed, embodiments of which include at least a layer of a non-evaporable getter alloy having a low activation temperature over a layer of a different non-evaporable getter material having high specific surface area, both preferably obtained by cathodic deposition. The multilayer NEG structures exhibit better gas sorbing characteristics and lower activation temperature lower than those of deposits made up of a single material. A process for manufacturing such structures includes depositing a first, high surface area NEG film on a support, and then depositing a thin over layer of low activation NEG film.Type: GrantFiled: June 10, 2004Date of Patent: August 19, 2008Assignee: SAES Getters S.p.A.Inventors: Andrea Conte, Marco Moraja
