    Abstract: A process management system can include a processing device that can be configured to perform a semiconductor process on a plurality of wafers, the processing device controlled by a process parameter. A control device can be configured to acquire statistical data relating to the process parameter and can be configured to select a reference wafer from the plurality of wafers. The control device can be configured to compare a respective process parameter used for the reference wafer with the statistical data and can be configured to set a reference condition for the process parameter.

    Abstract: A method for manufacturing a semiconductor device includes generating light, modulating power of the light to generate power-modulated light, acquiring an image signal of a measurement target using the power-modulated light, filtering the image signal to separate a real signal and a false signal, analyzing the measurement target using the real signal, and performing a semiconductor process on the measurement target based analyzing the measurement target using the real signal, wherein filtering the image signal includes classifying a first component of the image signal that is dependent on power of the power-modulated light as the real signal, and classifying a second component of the image signal that is independent of the power of the power-modulated light as the false signal.

    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.
