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.
