Abstract
A method for electrically coupling a first set of electrically conductive pads on a first semiconductor substrate to a second set of electrically conductive pads on a second semiconductor substrate is described. Dielectric material of a first thickness is deposited on at least one set of the first and second sets of electrically conductive pads. The first and second semiconductor substrates are then attached together such that such that the first and second sets of pads are substantially aligned parallel to one another and such that the dielectric material is disposed between the first and second sets of electrically conductive pads.
