A disposable absorbent pant having single-section side stretch panels is disclosed. The pant may have features including seams of overlapping configuration or sandwiched configuration, or a belt configuration. A seam of overlapping configuration may be formed by bonds with features that provide for tensile strength in a lateral direction, while providing enhanced tearability for convenient removal, and may include additional features including indicia of a tearing location, a tear-inducing notch, and structure to grasp for tearing. A seam of sandwiched configuration may provide a finished outward appearance. A belt configuration provides counterbalancing of lateral tension forces and reduces demand for structural robustness in backsheet materials, seams and bonds. Sandwiched and belt configurations allow for extended lateral width of side panels and increased stretch, without extending overall hoop circumference at risk of unduly loose fit.

A resistive heater element is integrally formed with a beam shaping aperture foil by lithographic patterning of a doped semiconductor layer of which the aperture foil is formed over an insulator, resulting in a device of greatly increased structural robustness and reliability.
