One or more aspects of the present invention are directed to a frequency-doubling circuit arrangement that doubles the frequency of a signal applied to its input, and presents that doubled frequency signal at its output. The method facilitates the control of the shape or dimensions of a pattern obtained by microfabrication, allows an accurate pattern transfer, and provides superior uniformity. By limiting the current flowing through the switch, current spikes are avoided, which reduces high frequency distortion. Further, the method includes extracting depth data of static objects in the stereoscopic pair. The MIS transistor includes a gate insulating film formed on the region, a gate electrode formed on the gate insulating film and fully silicided with metal, sourcedrain regions formed in parts of the region on the sides of the gate electrode and an insulating film formed to cover the gate electrode and the sourcedrain regions to cause stress strain in part of the region below the gate electrode. At least two patterns are printed in the border area of a document, where each of the patterns are a different color and different in color from the background of the document.
