Abstract

In a manufacturing method for a semiconductor device, a main body wafer is formed, and a monitor wafer on which a monitor element is formed is provided. Characteristics of the main body wafer are copied onto the monitor element by simultaneously processing the main body wafer and the monitor wafer. The characteristic of the monitor element is measured by checking a process influence of the monitor element. Manufacturing conditions are set in accordance with the process influence of the monitor element. Variations in electric characteristics of the main body wafer are reduced in accordance with the set manufacturing conditions.
