Abstract:
1. A method for forming an electrostatic discharge (ESD) protected electronic apparatus, comprising: providing a substrate; forming a dielectric layer over the substrate; forming a conductive layer over the dielectric layer; forming a first down-lead extending from the conductive layer, through the dielectric layer, and to the substrate; forming a second down-lead extending from the conductive layer, through the dielectric layer, and to the substrate, the second down-lead laterally spaced apart from the first down-lead; and forming at least one passive element electrically coupled to the first down-lead; wherein the first down-lead, the second down-lead, and the substrate are formed such that a charge leakage resistance path is created between the first-down lead and the second down-lead through the substrate, the charge leakage resistance path protecting the at least one passive element by inhibiting the accumulation of static charge during operation of the ESD protected electronic apparatus, the resistance between the first and second down-leads being at least 100 times an operating impedance of the ESD protected electronic apparatus.
