Abstract:
1. A method of forming an electrically conductive resistive layer comprising the steps of: forming an electrically conductive material onto a substrate; forming a first meander shape of the electrically conductive resistive layer having an end area by removing areas of the electrically conductive resistive layer while continuously measuring electrical resistance of the electrically conductive resistive layer, a size of the end area being selected such that the electrical resistance of the electrically conductive resistive layer with the end area is lower than a desired electrical resistance; and reducing the size of the end area until the electrical resistance reaches the desired electrical resistance, wherein the step of forming a first meander shape of the electrically conductive resistive layer having an end area by removing areas of the electrically conductive resistive layer while continuously measuring electrical resistance of the electrically conductive resistive layer and the step of reducing the size of the end area are continuously performed without interruption.
