    • Disclosed is a surface treating method wherein the surface of a base (11) exposed between multilayer films (13) is processed with a plasma (28) while a patterned metal wiring layer (15) is not exposed to the plasma (28) since a wiring board (10) is exposed to the plasma (28) with the patterned metal wiring layer (15) covered with a protective layer (18). Consequently, in cases where the metal wiring layer (15) is composed of copper, a copper nitrate is not formed on the surface of the metal wiring layer (15) even when the atmosphere comes into the space where the plasma is generated. The metal wiring layer (15) is thus prevented from deterioration, and a highly reliable electrical device can be obtained by connecting a wiring board (10) treated by such a surface treating method to an electrical component.
    • 公开了一种表面处理方法,其中暴露在多层膜(13)之间的基底(11)的表面用等离子体(28)进行处理,而图案化的金属布线层(15)不暴露于等离子体(28),因为 布线板(10)暴露于等离子体(28),图案化的金属布线层(15)被保护层(18)覆盖。 因此,在金属配线层(15)由铜构成的情况下,即使当气氛进入产生等离子体的空间时,也不会在金属配线层(15)的表面上形成硝酸铜。 因此可以防止金属布线层(15)劣化,并且通过将通过这种表面处理方法处理的布线板(10)与电气部件连接,可以获得高度可靠的电气装置。

    • A metal eliminating solution is provided to selectively remove palladium, tin, silver, palladium alloy, silver alloy, and tin alloy without attacking copper, contain no harmful material, and have an easy handling property. A metal eliminating solution eliminates palladium, tin, silver, palladium alloy, silver alloy, and tin alloy. The metal eliminating solution comprises 0.05-80wt% of a chain-like thiocarbonyl compound. The chain-like thiocarbonyl compound is at least one compound selected from thiourea compounds, thiuram compounds, dithiocarbamic acid compounds, xanthogenic acid compounds, ethylmethylthioketone, 2,4-pentanedithione, 2-thioxo-4-thiazolidinone(rhodanine), 2-thiouracil, and thioacetamide.
