摘要:
An integrated circuit die has a dielectric layer positioned over all the contact pads on the integrated circuit die. Openings are provided in the dielectric layer over each of the contact pads of the integrated circuit die in order to permit electrical coupling to be made between the integrated circuit and circuit boards outside of the die. For those contact pads located in the central region of the die, the opening in the dielectric layer is in a central region of the contact pad. For those contact pads located in a peripheral region of the die, spaced adjacent the perimeter die, the opening in the dielectric layer is offset from the center of the contact pad and is positioned closer to the central region of the die than the center of the contact pad is to the central region of the die.

An integrated circuit package structure includes a bottom portion having a cavity, an integrated circuit attached to a top surface of the stepped cavity, a leadframe attached to the bottom portion, wire bonding for electrically coupling the integrated circuit to the leadframe, and a top portion conformally covering the integrated circuit and the bottom portion.

A leadframe includes a die pad and a protective wall surrounding the die pad. A semiconductor die is situated on the die pad. Indentations are formed on the four inner corners of the protective wall adjacent the corners of the semiconductor die.
