External connections are made in an electronic device (11) having on an upper surface an array of contact pads (12) by providing successively over the electronic device a first anisotropic member (13), a first flat insulator member (14) having on an upper surface a first conductor pattern (29), a second flat anisotropic conductor member (15), and a second flat insulator member (17) having on an upper surface a second conductor pattern (30). The two flat insulator members contain an array of conductive vias (25, 26) extending between opposite surfaces. The first anisotropic conductor member (13) and a first array of conductive vias (25) extending through the first insulative member (14) interconnect a first plurality of contact pads (12) on the electronic device (11) to the first conductor pattern (29) which includes a peripheral array of contact pads (32) to which external connections are made. Means for interconnecting a second plurality of the contact pads on the electronic device to the second conductor pattern (30) comprise the second flat anisotropic conductor member (15) and a second array of conductive vias (26) extending through the second insulator member (17), the first array of conductive vias (25) and the first anisotropic conductor member (13). <IMAGE> |
