Abstract
A method of assembling an electronic device includes testing a first wafer of first die to identify the location of functional first die and dividing the first wafer into a set of panels, wherein a panel includes an M×N array of first die. A panel is bonded to a panel site of a second wafer to form a panel stack wherein a panel site defines an M×N array of second die in the second wafer. The panel stack is sawed into a devices comprising a first die bonded to a second die. Dividing the first wafer into panels may be done according statically or dynamically (to maximize the number of panels having a yield exceeding a specified threshold). Binning of the panels and panel sites according to functional die patterns may be performed to preferentially bond panels to panel sites of the same bin.
