Briefly, embodiments of claimed subject matter relate to devices and methods for modifying, such as decreasing rise time and/or fall time, of a driver signal output. To achieve such modifications in driver output signals, additional gates may be positioned at PMOS and/or NMOS regions of a semiconductor film. In addition, at least in particular embodiments, etching of portions of one or more semiconductor regions may increase compressive or tensile stress, which may further operate to modify driver output signals.
