Patent number: 6726987Abstract: The wearing part, such as a cutting insert, is made from hard metal or cermet. A hard-material coating is applied on the base material. The coating includes a single-layer or multilayer mixed-oxide coat, predominantly comprising Al2O3, in which defined proportions of titanium oxide and boron oxide are dissolved or homogeneously distributed extremely finely. The wearing part is distinguished by a high wear resistance, which improves the service life, and a fine-grained structure and uniformity of the coat and by a highly economic application of the coat.Type: GrantFiled: February 5, 2002Date of Patent: April 27, 2004Assignee: Plansee Tizit AktiengesellschaftInventors: Martin Kathrein, Wilfried Schintlmeister, Wolfgang Wallgram

Publication number: 20040058139Abstract: Seed layer treatment to remove impurities in the seed layer that might lead to the formation of voids in interconnect circuit features. In one embodiment, the seed layer is heated in a reducing environment. In another embodiment, the seed layer is washed with a surfactant that is compatible with a surfactant used when forming the remainder of the circuit feature on the seed layer. Yet another embodiment combines both techniques.Type: ApplicationFiled: September 23, 2002Publication date: March 25, 2004Inventors: Valery M. Dubin, Christopher D. Thomas, Vinay B. Chikarmane
