摘要:
Method for producing a thin film resistor by vapor deposition or cathode sputtering techniques, wherein part of the resistance area of the film is covered by an electrically insulating layer which prevents oxygen diffusion onto the resistance material and causes a decrease of the resistance during aging, while the rest of the resistance area remains free.
