Abstract:
A scanning probe inspector comprises: a probe that includes a cantilever and a tip whose length corresponds to a depth of a trench that is formed in a wafer; a trench detector that acquires location information of the trench using the probe, where the location information includes depth information of the trench; a controller that inserts the tip into a first point where there exists a trench based on the location information of the trench, and moves the tip through the trench using the location information of the trench; and a defect detector that detects a presence of a defect in a sidewall of the trench as the tip is moved through the trench.

Claim (Index 9):
The scanning probe inspector of  claim 8 , wherein\n the controller inserts the tip into the first point up to a first depth or up to a second depth that differs from the first depth, and moves the tip along the trench based on the location information of the trench, and the defect detector includes a DC bias voltage supplier that supplies a DC bias voltage to the wafer and the probe, an RF signal supplier that supplies an RF signal to the probe wherein the RF signal is emitted from the entire probe, a signal detector that detects a first RF signal reflected from the trench as the tip is moved along the trench at the first depth, and detects a second RF signal reflected from the trench as the tip is moved along the trench at the second depth, and an analyzer that detects the defect in the trench based on variations in a difference between the first and second RF signals.
