We have developed technological processes to assemble interconnect net
works for multichip modules (MCM). Copper is used as conductor materia
l. A new polymeric material, fully cyclised in solution, is used as di
electric. The multi-layered structure is deposited on highly doped sil
icon substrate used as ground plane. We present several physical, mech
anical and electrical characterizations performed all along the networ
k assembling.
