  • Publication number: 20130043577
    Abstract: In a semiconductor device, a lead frame made of a copper alloy prevents exfoliation occurring near the surface of the lead frame. A copper oxide layer is formed on the base material made of a copper alloy by immersing the base material into a solution of a strong oxidizer. The copper oxide layer serves as an outermost layer and consists of a copper oxide other than a copper oxide in the form of needle crystals.
