Abstract: A multi-chip package may include a first semiconductor chip, a second semiconductor chip, a first stud bump, a first nail head bonding bump, a second stud bump, and a first conductive wire. The first semiconductor chip may have a first bonding pad. The second semiconductor chip may be stacked on the first semiconductor chip so the first bonding pad remains exposed. The second semiconductor chip may have a second bonding pad. The first stud bump may be formed on the first bonding pad. The first nail head bonding bump may be formed on the first stud bump, with one end of a first conductive wire formed between the two. The second stud bump may be formed on the second bonding pad, with another end of the first conductive wire formed between the two. An electrical connection test may be performed on each of the wire bonding processes.
