摘要 |
本发明系关于接合线,其包含具有表面之核心,其中该核心包含铜作为主要组份;及叠加于该核心之该表面上之涂覆层,其中该涂覆层包含钯作为主要组份,其中该核心包含至少5ppm银及至少20ppm磷作为其他组份,其中该线满足关系;0.000025<E/(d*CAg)<0.15,其中E系以%量测之该线之伸长率,d系以μm量测之该线之直径,且CAg系以ppm量测之该线核心之该银含量。; E/(d*CAg) < 0.15, wherein E is an elongation of the wire measured in %, d is a diameter of the wire measured in μm and CAg is the silver content of the wire core measured in ppm. |
