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.

摘要:
An embodiment of a MIM capacitor includes a first insulating layer formed over a wafer and a first capacitor plate formed over the wafer within the first insulating layer. The MIM capacitor further includes a second insulating layer formed over the first insulating layer, a capacitor dielectric formed over the first capacitor plate within the second insulating layer and a second capacitor plate formed over the capacitor dielectric within the second insulating layer. A recess is formed in the second capacitor plate below an upper surface of the second insulating layer and a catalytic activation layer is formed in the recess.

摘要:
In a method of fabricating a semiconductor device, a level of metal is formed within an interval dielectric. The level of metal includes a first metal line separated from a second metal line by a region of the interlevel dielectric. The region of interlevel dielectric is removed between the first metal line and the second metal line. A high-k dielectric is formed between the first metal line and the second metal line in the region where the interlevel dielectric was removed such that a capacitor is formed by the first metal line, the second metal line and the high-k dielectric.

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.

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.
