发明名称 Methods of making anisotropic conductive elements for use in microelectronic packaging
摘要 A layer of an anisotropic material has a pair of substantially flat oppositely-directed major faces, a vertical direction extending between the faces and horizontal directions transverse to the vertical direction, the layer including a dielectric material and a plurality of conductive particles in the dielectric material. The particles are distributed non-uniformly in the horizontal directions so as to provide areas of high particle concentration interspersed with areas of low particle concentration.
