Apparatuses and methods for a self-biased delay looked loop with delay linearization are provided. The acoustic sensor further includes a housing substantially surrounding the at least one photonic crystal structure and mechanically coupled to the at least one photonic crystal structure. An image formation unit forms a two-dimensional image based on the stored associated luminance and positional information. For an nMOSFET, the conductive layer has a compressive stress to apply a tensile stress to the channel region; and for a pMOSFET, the conductive layer has a tensile stress to apply a compressive stress to the channel region. A standard plunge that has an aft plunge portion is also included.
