What is a dielectric layer?
Geometry Elements - Dielectric Layers
The circuit geometry consists of alternate dielectric layers and metal levels enclosed in a six-sided metal box. Each time you add a dielectric layer you add a metal level.
The example below shows a 3-D drawing of a circuit (with the z-axis exaggerated) on the left side with the Dielectric Layers dialog box for the same circuit shown on the right.
It is important to note that the metal level is associated with the dielectric layer ABOVE it. If that dielectric layer is deleted from the circuit, then the metalization below it is also deleted. For example, if you deleted the dielectric layer between metal levels 1 and 2 in the example shown below, the level 2 metalization would also be removed.
The type of dielectric is specified for each dielectric layer by entering the dielectric constant and loss parameters for each layer in the Dielectric Layers dialog box. For more details about these parameters, see Circuit => Dielectric Layers
