Abstract:
Devices and methods for forming semiconductor devices with a protection layer for a dielectric mask layer are provided. One method includes, for instance; obtaining a substrate having at least one of a dielectric layer and a metal layer; forming a first SiCN dielectric mask layer on a top surface of at least one of the dielectric layer and a metal layer; and forming a silicon nitride (SiNx) cap layer on a top surface of the first SiCN dielectric mask layer. One intermediate semiconductor device includes, for instance: a substrate having at least one of a dielectric layer and a metal layer; a first SiCN dielectric mask layer on a top surface of at least one of the dielectric layer and a metal layer; and a silicon nitride (SiNx) cap layer on a top surface of the first SiCN dielectric mask layer.
Abstract:
Through-silicon-vias (TSV) to back end of line (BEOL) integration structures and a method of manufacturing the same are disclosed. Embodiments include providing a bottom die of a three-dimensional (3D) integrated circuit (IC) stack, the bottom die having a connection pad; providing a top die of the 3D IC stack, the top die including a plurality of metallization layers having a plurality of intermetal vias provided between the plurality of metallization layers; forming a BEOL connection structure between the bottom and top dies, the BEOL connection structure having a plurality of power supply TSVs; and connecting the connection pad electrically to the intermetal vias through the power supply TSVs.
