Abstract:
Semiconductor devices, packaging architectures and associated methods are disclosed. In one embodiment, a semiconductor device is disclosed. The semiconductor device includes a first semiconductor die having a first bonding surface that is formed with a first set of contacts patterned with a first connection pitch. A second semiconductor die has a second bonding surface that is formed with a second set of contacts patterned with a second connection pitch. The second set of contacts are further patterned with a paired offset. The second semiconductor die is bonded to the first semiconductor die such that the first set of contacts is disposed in opposed electrical engagement with at least a portion of the second set of contacts.
