PROBLEM TO BE SOLVED: To provide a semiconductor package avoiding a solder joining defect due to warpage of a substrate. SOLUTION: The semiconductor package 200 has a first semiconductor package 210, a package carrier 220 and a solder material 230. The solder material 230 is used to solder and join external terminals 213 and 214 of the semiconductor package 210 to the package carrier 220. The external terminals 213 and 214 of the semiconductor package 210 are divided into at least two groups because of difference in distances from the center line of the substrate. The external connection terminals 213 and 214 in the different groups have bumps differing in height for compensation of solder material gap differences occurring when the groups of the external connection terminals 213 and 214 and the package carrier 220 are joined owing to the predicted warpage of the substrate and then the warpage of the substrate is predicted to suppress the occurrence of the solder joining defect.
