This paper is dedicated to the full development of several technological modules mandatory for 3-D multiple die stacking. This includes technologies such as thinning, Through Silicon Vias (TSV) and dies interconnection. A via last approach was chosen to be compatible with die integration coming from various foundries where design, die thickness and contact pad metallurgy are predefined. The interconnection between each die is based on chip on wafer bonding and micro-inserts technology. Small… CONTINUE READING
