Definition
An insulator is a material with very low electrical conductivity that resists charge transport; in semiconductor devices, dielectric films are used as insulating layers between conductive or semiconducting regions.
Application
Insulating dielectrics provide electrical isolation in transistor structures, interconnect stacks, passivation layers, and other chip structures where unwanted current flow must be suppressed.
