Abstract: A packaged microchip has a base, a die with a mounting surface, and an electrically inactive interposer between the base and the die. The interposer has a first side with at least one recess that extends no more than part-way through the interposer from the first side. Accordingly, the recess defines a top portion (of the first side) with a top area. The die mounting surface, which is coupled with the interposer, correspondingly has a die area. The top area of the interposer preferably is less than the die area.

Abstract: An integrated circuit package system having a body with a top surface, a bottom surface, and a plurality of side surfaces has a leadframe and encapsulating material that encapsulates at least a portion of the leadframe. The leadframe and encapsulating material are part of the body. The leadframe has a die paddle for supporting a die, and a plurality of leads spaced from the die paddle. The encapsulating material thus also separates the die paddle from the plurality of leads. At least a first portion of the die paddle is exposed to the top surface, while at least a second portion of the die paddle is exposed to the bottom surface.
