The present invention provides a semiconductor pattern shape evaluating apparatus using a critical dimension SEM, which eliminates the necessity of data conversion corresponding to each process of semiconductor manufacturing conventionally required; controls possessed data integratedly; can select data effective for use in each process from the possessed data easily; if the shape of formed pattern changes with time, can create a photographing recipe which enables stable measurement by correcting the photographing recipe based on time-series data. Specifically, the semiconductor pattern shape evaluating apparatus correlates coordinate systems among diversified data to control the diversified data stored in a database integratedly, selects part or all of the diversified data arbitrarily and creates a photographing recipe for observing a semiconductor pattern with a critical dimension SEM using selected data.
