Abstract:
1. A method of fabricating a resistive probe having a self-aligned metal shield, the method comprising: forming a resistive tip on a substrate that is doped with a first impurity, the resistive tip comprising a resistive region formed at a peak thereof and lightly doped with a second impurity, which is opposite in polarity to the first impurity, and first and second electrode regions formed on inclined surfaces thereof and heavily doped with the second impurity; sequentially forming a first insulating layer and a metal shield on the resistive tip; uniformly forming a second insulating layer to cover the metal shield; etching the second insulating layer to expose the metal shield on the resistive region; etching the exposed metal shield; and etching the first insulating layer to expose the resistive region.
