METHOD FOR MAKING A HEATING ELEMENT BY DEPOSITING THIN LAYERS ONTO AN INSULATING SUBSTRATE, AND RESULTING ELEMENT

摘要

A method for fabricating a heating a element includes modifying the surface state of a substrate in order to obtain at least one smooth area of low roughness and at least one rough area having a higher roughness; applying a highly electrically conductive material to these various areas; and connecting smooth area(s) of the conductive material to an electrical power source.
