Permittivity of dielectric
WebThe ultimate low-κ material is air with a relative permittivity value of ~1.0. However, the placement of air gaps between the conducting wires compromises the mechanical stability of the integrated circuit making it impractical to build an IC consisting entirely of air as the insulating material. WebThe dielectric constant formula is: Where: C = capacitance using the material as the dielectric capacitor. C 0 = capacitance using vacuum as the dielectric. ε 0 = Permittivity of free space (8.85 x 10 -12 F/m i.e. Farad per metre) A = Area of the plate/sample cross section area. T = Thickness of the sample.
