Abstract:
1. A manufacturing method for a semiconductor device, comprising the steps of: selecting as a monitoring step, one step from a plurality of steps in a main body wafer manufacturing process for manufacturing a main body wafer on which the semiconductor device is formed; selecting as a variation reduction step, one step from main body post-process steps succeeding the monitoring step; a monitor wafer manufacturing process for manufacturing a monitor wafer on which a monitor element is formed, the monitor wafer manufacturing process comprising a monitor pre-process step, the monitoring step, a monitor post-process step, a quality check step of measuring a characteristic of the monitor element, and a condition setting step of setting a manufacturing condition in the variation reduction step based on a process influence measured in the quality check step; and performing the main body post-process step under the manufacturing condition set in the condition setting step.
