Improved apparatus and methods for stacking integrated circuit packages having leads are disclosed. According to one embodiment, the leads of an integrated circuit package are exposed and provided with solder balls so that corresponding leads of another integrated circuit package being stacked thereon can be electrically connected. The stacking results in increased integrated circuit density with respect to a substrate, yet the stacked integrated circuit packages are able to still enjoy having an overall thin or low profile.
