摘要:
A method, apparatus and system are provided for relieving stress in the via structures of semiconductor structures whenever a linewidth below a via is larger than a ground-rule, including providing a via at least as large as the groundrule, providing a landing pad above the via, providing a via bar in place of a via, slotting the metal linewidth below the via, or providing an oversize via with a sidewall spacer.

摘要:
A method for forming a MIM capacitor and a MIM capacitor device formed by same. A preferred embodiment comprises selectively forming a first cap layer over a wafer including a MIM capacitor bottom plate, and depositing an insulating layer over the MIM capacitor bottom plate. The insulating layer is patterned with a MIM capacitor top plate pattern, and a MIM dielectric material is deposited over the patterned insulating layer. A conductive material is deposited over the MIM dielectric material, and the wafer is planarized to remove the conductive material and MIM dielectric material from the top surface of the insulating layer and form a MIM capacitor top plate. A second cap layer is selectively formed over the MIM capacitor top plate.

In a semiconductor integrated circuit device, thermo-mechanical stresses on the vias can be reduced by introducing a stress relief layer between the vias and a hard dielectric layer that overlies the vias.
摘要:
A bond pad structure formed over a predetermined area of an IC substrate comprising quickly and easily removable redundancy and passivation layers upon lithography and plasma etching in a plasma containing Cl2, the bond structure comprises: a liner or lower metal layer formed on a predetermined area of the IC substrate; an aluminum-based metal layer formed on the liner layer as the last metal layer for bond purposes; a tungsten based redundancy layer formed on top of the aluminum-based last metal layer; and a passivation layer formed over the IC substrate and on the tungsten based redundancy layer.
摘要:
A process of making an interconnection structure of Cu FBEOL semiconductor devices that does not rely upon Al-wirebond pads which require additional patterning steps (for Al-via to Cu, Al-pad), including: a) providing a substrate having Cu wires and Cu pads embedded therein; b) selectively depositing a first metallic passivation layer on the top copper surfaces sufficient to prevent Cu oxidation and/or Cu out diffusion; c) depositing a final passivation layer; d) employing lithography and etching of the final passivation layer to cause pad opening of the fuses by exposing the passivated Cu in the bond pad area and in the fuse area; and e) causing additional passivation of open pad and open fuse areas by selective immersion deposition of Au.

摘要:
A method of making a metal-insulator-metal (MIM) capacitor (158) having self-passivating plates (143, 155). A liner (116) is deposited on a workpiece (112) and dielectric (114). A conductive layer (142) is deposited and annealed to form dopant-rich region (144). Insulating region (145) is formed on exposed portions of dopant-rich region (144) by exposure to atmosphere or oxygen. Capacitor dielectric layer (146) is disposed over the first capacitive plate (143). A second capacitive plate (155) is formed over the first capacitive plate (143) and capacitor dielectric layer (146). The second capacitive plate (155) is annealed to form dopant-rich region (154) and exposed to atmosphere or oxygen to form insulating region (156). Optional seed layer (140) may be deposited prior to the formation of the first capacitive plate (143).
