Abstract

A test method for a semiconductor device includes determining a contact failure between a first semiconductor chip and a second semiconductor chip during assembly of a semiconductor package including the first semiconductor chip and the second semiconductor chip, using a test circuit embedded in the first semiconductor chip, and after the assembly of the semiconductor package, determining whether the semiconductor package is defective by using the test circuit.
