Modified leadframe design with adhesive overflow recesses
The present disclosure is directed to a leadframe having a recess in a body of the leadframe to collect glue overflowing from the manufacturing process of coupling a semiconductor die to the leadframe. The recess extends beneath an edge of the semiconductor die so that any tendency of the glue to adhere to the semiconductor die is counteracted by a tendency of the glue to adhere to a wall of the recess and at least partially fill the volume of the recess. In addition, the recess for collecting adhesive may also form a mold lock on an edge of the leadframe, the mold lock providing a more durable connection between the leadframe and an encapsulant during physical and temperature stresses.

POWER MODULE AND POWER CONVERSION DEVICE
A power module is obtained in which the thermal resistance in the range from a semiconductor device to a base plate is reduced and the stress in the joining portion is relieved. The power module includes at least one semiconductor device, an insulating substrate having an insulating layer, a circuit layer provided on an upper surface of the insulating layer and a metal layer provided on a lower surface of the insulating layer, and a sintering joining member with an upper surface larger in outer circumference than a back surface of the at least one semiconductor device, to join together the back surface of the at least one semiconductor device and an upper surface of the circuit layer on an upper-surface side of the insulating layer.
SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREFOR
A semiconductor device includes a baseplate and a case which includes an external wall surrounding an internal space and a dividing wall extending in a first direction and separating the space into compartments. The dividing wall has a lower end fixed to the principal surface and includes, on a sidewall, a terrace positioned further away from the principal surface than the lower end and hanging out toward the space compared to the lower end in a second direction parallel to the principal surface and perpendicular to the first direction. A terminal's bonding part, to which a wire is bonded, is disposed on the terrace. A ratio of the wire's diameter to the bonding part's width in the first direction is set to ≤0.15, which prevents a situation where bonding power is not sufficiently applied to the bonding part during ultrasonic bonding of the wire, thus increasing the bonding strength.
