摘要:
Disclosed herein is a method of inspecting defects in a circuit pattern of a substrate. At least one laser beam radiation unit for radiating a laser beam onto an inspection target circuit pattern of a substrate in a non-contact manner is prepared. A probe beam radiation unit for radiating a probe beam onto a connection circuit pattern to be electrically connected to the inspection target circuit pattern in a non-contact manner is prepared. The laser beam is radiated onto the inspection target circuit pattern using the laser beam radiation unit. The probe beam is radiated onto the connection circuit pattern using the probe beam radiation unit, thus measuring information about whether the probe beam is diffracted, and a diffraction angle. Accordingly, the method can solve problems such as erroneous measurements caused by contact pressure and can reduce the time required for measurements.

Disclosed herein is an apparatus and method for inspecting defects in the circuit pattern of a substrate. The apparatus for inspecting defects in a circuit pattern of a substrate includes a pin probe configured to input a voltage while coming into contact with an inspection target circuit pattern of a substrate. A capacitor sensor is provided with a membrane electrode which is opposite a connection circuit pattern to be electrically connected to the inspection target circuit pattern in a non-contact manner, and is configured to detect both capacitance and capacitance variation, generated due to displacement of the membrane electrode attributable to electrostatic attractive force acting from the connection circuit pattern on the membrane electrode. A capacitance measurement unit is connected to the capacitor sensor and is configured to measure capacitance attributable to the displacement of the membrane electrode, which is input from the capacitor sensor.
