Abstract: Apparatuses and methods can include a die seal between an integrated circuit region of a die and a periphery of the die. A via chain(s) may be arranged around an inner circumference of the die seal between the die seal and the integrated circuit region and/or around an outer circumference of the die seal between the die seal and the periphery of the die. The via chain may include a plurality of contacts comprised of conductive material and extending through portions of the die. Circuitry may be coupled to an end of the via chain to detect an electrical signal. Additional apparatuses and methods are described.

Abstract: Microelectronic devices with through-silicon vias and associated methods of manufacturing such devices. One embodiment of a method for forming tungsten through-silicon vias comprising forming an opening having a sidewall such that the opening extends through at least a portion of a substrate on which microelectronic structures have been formed. The method can further include lining the sidewall with a dielectric material, depositing tungsten on the dielectric material such that a cavity extends through at least a portion of the tungsten, and filling the cavity with a polysilicon material.
