A solid electrolytic capacitor 1 includes a capacitor element 2 and a resin package 9 enclosing the capacitor element. The system includes a polishing surface and a platen disposed along an underside of the polishing surface. Said precursor membrane is also subjected to the hydrolysis treatment under constraint, while the precursor membrane is maintained in a widened or a stretched state. In another example herein, a network to which a user device moves can determine whether to send an event notification to another network associated with the user device based on capabilities of the user device. Still further, the method forms a second transistor gate electrode comprising a silicide of the metal portion in a fixed relationship with respect to the gate dielectric.
