Abstract
An electrical device that is electrically and mechanically connectable to another electrical device includes a face equipped with contact pads. An adhesive layer is on the face equipped with the contact pads. The adhesive layer is composed of a substance with adhesive properties. A plurality of openings through the adhesive are layer over each contact pad, and small metal sticks which have been grown electrolessly or electrochemically are in the areas where the openings have been created to form a plurality of conductive paths over each contact pad, the volume of which is defined by the openings.
Claims10
An electrical assembly, comprising:
- a first electrical device and a second electrical device, the first electrical device including a first face including a plurality of first contact pads and the second electrical device including a second face including a plurality of second contact pads, the plurality of first contact pads facing the plurality of second contact pads, the first electrical device and the second electrical device electrically connected to each other by means of a connection layer comprising a substance with adhesive properties, wherein said connection layer comprises a plurality of conductive paths over each contact pad formed by a plurality of openings that extend through the connection layer and in which metal sticks have been grown using electroless or electrochemistry, said metal sticks are configured to extended beyond a plane of the connection layer.
