Abstract: A semiconductor device includes: a semiconductor chip including a field effect transistor for switching; a die pad on which the semiconductor chip is mounted via a first bonding material; a lead electrically connected to a pad for source of the semiconductor chip through a metal plate; a lead coupling portion formed integrally with the lead; and a sealing portion for sealing them. A back surface electrode for drain of the semiconductor chip and the die pad are bonded via the first bonding material, the metal plate and the pad for source of the semiconductor chip are bonded via a second bonding material, and the metal plate and the lead coupling portion are bonded via a third bonding material. The first, second, and third bonding materials have conductivity, and an elastic modulus of each of the first and second bonding materials is lower than that of the third bonding material.

Abstract: An improvement is achieved in the performance of a semiconductor device. A second component mounting portion over which a first electronic component is mounted is connected to a coupling portion of a lead frame via a suspension lead. The suspension lead has a first portion between the second component mounting portion and the coupling portion and a second portion between the first portion and the coupling portion. The second portion has a third portion connected to the first portion and having a width smaller than a width of the first portion, a fourth portion connected to the first portion and having a width smaller than the width of the first portion, and a through hole (opening) located between the third and fourth portions. Each of the first, third, and fourth portions has the same thickness. After a sealing body is formed, a cutting jig is pressed against the suspension lead to cut the suspension lead.
