Abstract
A low-pin-count chip package including a die pad for receiving a semiconductor chip and a plurality of connection pads electrically coupled to the semiconductor chip. The semiconductor chip, the die pad, and the connection pads are encapsulated by a package body in a manner that the lower surfaces of the die pad and the connection pads are exposed through the package body. The present invention is characterized in that the die pad and the connection pads have a T-shaped profile thereby prolonging the time for moisture diffusion into the package as well as enhancing the “locking” of the die pad and the connection pads in the package body. The present invention further provides a method of producing the low-pin-count chip package described above.
