A method for fabricating a silicon on substrate structure having smooth edge regions. The apparatus includes a horn having an elongated and flat sealing face and an opposing jaw with an action face including a pressing portion for pressing the packing material in cooperation with the sealing face of the horn to a define at least one transverse sealing zone of the tubular packing material. Using this information, intelligently decomposed objects, consolidated objects, differenced objects, and composite objects may be stored in the storage system. The planar elements are individually controlled using a central control unit such that each planar element assumes a respective one of at least two states in accordance with the control so as to influence the radiation.
