ABSTRACT:
Method for producing a resistive heating element by coating a substrate with an electrically insulating material from the gaseous phase, depositing an electrically conducting material from the gaseous phase onto the layer of insulating material deposited onto the substrate, wherein the layer of conducting material deposited onto the layer of insulating material is subsequently partially mechanically removed thereby forming at least one conductor path. The substrate is machined before depositing the insulating material thereby forming at least one recess provided for receiving the conductor path. The layers of insulating material and conducting material are deposited onto the mechanically processed substrate. Finally, the layer of conducting material is evenly removed until at least the conducting material has been completely removed from the elevated regions of the substrate delimiting the recess of the conductor path, thereby forming the conductor path. The invention also concerns a resistive heating element produced in this fashion.
