A method of roll forming a metal plate with a desired bend. Switching elements, by means of which conductor paths between the contacts can be modified, are positioned on the circuit board. An adhesive strip, preferably a double-sided adhesive strip, attaches the non-adhesive side of the adhesive-sided article to the top backing sheet. The first sensor sends a first signal in response to sensing the part and the second sensor sends a second, subsequent signal in response to sensing the part. The ferroelectric gate capacitor structure includes a dielectric film, ferroelectric film, and upper electrode formed in this order from the substrate side.
