ABSTRACT:
Stacked semiconductor chips are disclosed. One embodiment provides a method including a first substrate having a first surface and an opposing second surface. The first substrate includes an array of first connection elements on the first surface of the first substrate. A second substrate has a first surface and an opposing second surface. The second substrate includes an array of second connection elements on the first surface of the second substrate. The first connection elements is attached to the second connection elements; and is thinning at least one of the first substrate and the second substrate after the attachment of the first connection elements to the second connection elements.
