<P>PROBLEM TO BE SOLVED: To provide a compact pad on a converter head improved in abrasion resistance. <P>SOLUTION: A compact pad comprises a first layer made of a material having a first yield strength and a second layer which is laminated on the first layer and has a second yield strength. A third yield strength of a laminated composite body consisting of the first layer and the second layer exceeds the first yield strength and the second yield strength due to the Hall-Petch phenomenon. An overcoat covers an edge of the first layer and the second layer of the contact pad to prevent wear. A method for producing the contact pad or other microelectronic structure includes depositing a first layer made of a material having a first yield strength on a substrate. A second layer made of a material having a second yield strength is deposited on the first layer. The edge of the first layer and the second layer is coated with an overcoat material to prevent wear of the first and second layers. <P>COPYRIGHT: (C)2012,JPO&INPIT |
