Classification: CPC H | IPC H

Claim 0:
1. A multi-die structure, comprising:
a first die group including a plurality of first dies stacked parallel to each other and parallel to a front surface of the first die group, wherein the first die group is disposed on a top surface of a third die group, and the front surface of the first die group and the top surface of the third die group intersect at a first edge, and the first edge extends in a first direction in the top surface of the third die group;
a first bonding member on the first die group;
a second die group including a plurality of second dies stacked parallel to each other and parallel to a front surface of the second die group, wherein the second die group is disposed on the top surface of the third die group, and the front surface of the second die group and the top surface of the third die group intersect at a second edge, the second edge extends in a second direction in the top surface of the third die group;
a second bonding member on the second die group;
the third die group comprising a substrate characterized by a lattice crystalline plane, wherein the lattice crystalline plane, when projected on the top surface of the third die group, extends in a third direction; and
a third bonding member on the third die group;
wherein the first bonding member on the first die group is in contact with the upper surface of the third bonding member on the third die group;
wherein of the second bonding member on the second die group is in contact with the third bonding member on the third die group; and
wherein the first direction and the third direction define a first angle, the second direction and the third direction define a second angle, and at least one of the first angle and the second angle is not zero.
