Patent ID: 7994499

Claim:
A semiconductor probe comprising: a resistive tip that is doped with a first impurity, has a resistance region doped with a low concentration of a second impurity having an opposite polarity to the first impurity, and has first and second semiconductor electrode regions doped with a high concentration of the second impurity on both side slopes of the resistive tip; and a cantilever having the resistive tip on an edge portion thereof, wherein an end portion of the resistive tip has a wedge shape, wherein the end portion in a length direction of the wedge shape of the resistive tip is a single flat surface comprising: a first side portion formed by an end portion of the first semiconductor electrode region, a second side portion formed by an end portion of the second semiconductor electrode region, and a central portion interposed between the first and second side portions and formed by an end portion of the resistance region, wherein the end portion of the first semiconductor electrode region, the end portion of the second semiconductor electrode region and the end portion of the resistance region are flat surfaces on a same plane.
