1. An isolated micro-scale passive device comprising:
a first conductor and a second conductor formed on a substrate;
a first insulator layer disposed over the first conductor;
a second insulator layer disposed at least partially between the first insulator layer and the second conductor; and
a plurality of conductive or nonlinear conductive particles embedded in at least a portion of the second insulator layer, wherein:
a first portion of the second insulator layer has a first conductivity; and
the plurality of conductive or nonlinear conductive particles define a second portion of the second insulator layer with a second conductivity greater than the first conductivity.
