In order to provide a semiconductor device evaluation method and a semiconductor device evaluation apparatus for correctly detecting an error position and providing a substrate for observing a cross section without difficulties, a transport unit of a SEM apparatus moves a substrate on a stage. A detection unit detects electric information of observed objects including an error position arranged on the substrate. A calculating unit calculates integrals based on the electric information in at least first and second directions among directions in which arrays of the observed objects are arranged, detects a first waveform obtained by calculating the integral in the first direction and detects a second waveform obtained by calculating the integral in the second direction, wherein the first waveform includes a peak which contains the array of the observed objects including the error position and is larger than at least one of the other peaks, and wherein the second integral-waveform has peaks of substantially the same height. A control unit controls the transport unit so as to move the semiconductor substrate in a direction for maintaining the peak of the first waveform that includes the error position and controls the calculating unit to count the peaks of the second waveform.

摘要:
A silicon ingot is manufactured by pulling a nitrogen doped silicon single crystal. The oxygen concentration in the crystal is controlled during the pulling, so as to maintain a relationship between the oxygen and nitrogen concentration in the ingot, corresponding to the formula Oi=C1−[C2×(Log Ni)], where C1 and C2 are first and second constants, and Oi is the oxygen concentration and Ni is the nitrogen concentration in the ingot. C1 and C2 will vary depending on the defect criteria. For example, for one criteria C1 may equal to 146.3×1017 and C2 may equal to 9×1017, and Ni may be within the range of approximately 3×1015 to approximately 3×1014 atoms/cm3, while for a stricter defect criteria C1 may equal 127×1017 and C2 may equal 8×1017, and Ni may be within the range proximately 1×1015 to approximately 1×1014 atoms/cm3.
