Patent ID: 8653640

Claim:
A semiconductor package apparatus comprising: a first semiconductor package comprising: a first substrate; a first semiconductor chip on the first substrate; at least one first terminal formed on the first substrate; and a first signal transfer medium electrically connecting the first semiconductor chip and the first terminal to each other; a second semiconductor package comprising: a second substrate; a second semiconductor chip on the second substrate; at least one second terminal formed on the second substrate; and a second signal transfer medium electrically connecting the second semiconductor chip and the second terminal to each other; at least one package connecting solder ball between the first terminal and the second terminal for electrically connecting the first and second terminals to each other; a first solder ball guide member around the first terminal of the first substrate and including inclined first guide surfaces adjacent the package connecting solder ball; and a second solder ball guide member around the second terminal of the second substrate and including inclined second guide surfaces adjacent the package connecting solder ball, wherein the first solder ball guide member has a thickness that is less than a thickness of the second solder ball guide member, and the first solder ball guide member contacts the second solder ball guide member.
