    Abstract: Integrated circuits including a MIMCAP device and methods of forming the integrated circuits are provided. An exemplary method of forming an integrated circuit including a MIMCAP device includes pre-determining a thickness of at least one of a bottom high-K layer or a top high-K layer of the MIMCAP device, followed by fabricating the MIMCAP device. The pre-determined thickness is established based upon a pre-determined TDDB lifetime for the MIMCAP device and a minimum target capacitance density at an applied voltage bias to be employed for the MIMCAP device. The MIMCAP device includes a bottom electrode and a dielectric layer disposed over the bottom electrode. The dielectric layer includes a stack of individual layers including the bottom high-K layer, the top high-K layer, and a lower-K layer sandwiched therebetween. At least one of the bottom high-K layer or the top high-K layer has the pre-determined thickness.

    Abstract: One illustrative crack-stop structure disclosed herein may include a first crack-stop metallization layer comprising a first metal line layer that has a plurality of openings formed therein and a second crack-stop metallization layer positioned above and adjacent the first crack-stop metallization layer, wherein the second crack-stop metallization layer has a second metal line layer and a via layer, and wherein the via layer comprises a plurality of vias having a portion that extends at least partially into the openings in the first metal line layer of the first crack-stop metallization layer so as to thereby form a stepped, non-planar interface between the first metal line layer of the first crack-stop metallization layer and the via layer of the second crack-stop metallization layer.
