Abstract
Three-dimensional multichip module. The invention relates to a three-dimensional or 3D multichip module having a plurality of bidimensional, elementary electronic modules (4a-4d), each incorporating at least one chip (10a-10d), a support (6a-6d) on which is placed the chip and a conductive interconnection network or array (8a-8d) covering an upper surface of the support. These elementary modules are substantially superimposed in a displaced manner (in the form of a staircase) and are interconnected by means of their interconnection networks and connection pads (12a-12d) placed on those parts of the elementary modules not covered by the upper elementary module. Application to the association of integrated circuits in microconnection technology.
Claims4
Multichip module having a substrate (2) and plurality of bidimensional, elementary electronic modules (4a-4d), each having at least one chip (10-10d) and a support (6a-6d) on which is placed the chip, the elementary modules being substantially superimposed and deposited on the substrate, characterized in that the substrate and the supports of the elementary modules have in each case an upper face covered by an interconnection network and in that the elementary modules which are substantially superimposed are displaced with respect to one another and with respect to the substrate in such a way that a portion of each interconnection network is not covered by the support of an upper elementary module, so as to permit the interconnection of the interconnection networks by electric wires.
