A retractor has an elongate body and an expandable shroud. Such treatment of received programming content provides for efficient storage of such programming content, and effectively provides for access to such content by administrators of a broadband system as well as users of such systems. The photoresist layer is patterned to form photoresist features with photoresist sidewalls, where the photoresist features have a first critical dimension. The charge trapping structure may include a tunnel oxide layer pattern, a charge trapping layer pattern and a dielectric layer pattern of aluminum-containing tertiary metal oxide. The multicolor image and the hole array are both computer created and downloaded to a photo imager.
