Title:
半導体パッケージ
Document Type and Number:
Japanese Patent JP5256177
Kind Code:
B2
Abstract:
To prevent the peeling of a die pad and semiconductor chip in a semiconductor package which seals the semiconductor chip by a sealing resin in the state where the semiconductor chip is joined to a top surface of die pad in a plate form by soldering.
The semiconductor package 1 is structured such that: an engagement hole 13 having a bottom and sinking into the thickness direction of a die pad 3 from the top surface 3a is formed on the die pad 3; the engagement hole 13 is placed closer to the semiconductor chip 2 fixed on the die pad 3 than to the peripheral edge of top surface 3a of die pad 3; and a plurality of engagement holes 13 are arranged so as to surround the semiconductor chip 2.
