1. A microelectronic assembly comprising:
a substrate having a first lateral footprint;
a first die and a first bonding layer on the first die, the first die having a second lateral footprint, the first bonding layer directly bonded to the substrate without an adhesive;
a second die having a microelectronic circuit element formed therein and disposed over the first die, the second die having a third lateral footprint, the first die directly bonded to a second bonding layer on the second die without an adhesive;
a first compound disposed adjacent a side wall of the first die; and
a second compound deposited on and laterally adjacent the first compound,
wherein the second lateral footprint is smaller than the first lateral footprint and smaller than the third lateral footprint.
