A method for a computer system to allow user editing of a help item that is associated with an element in an uninterrupted user session. The vehicle body structure has an input conversion structure configured to convert a side-impact input that acts inwardly on the pillar member in a substantially horizontal direction from the vehicle exterior to an input that is applied to the pillar member in the vertical direction of the vehicle body. Thus, a method of manufacturing a semiconductor wafer capable of efficiently manufacturing the semiconductor wafer regardless of the type of a base, and a composite base and a composite substrate suitably used in that manufacturing method are provided to efficiently manufacture a semiconductor device.
