A simply formed and rigid contact holding structure of a connector in which the positions of the contact parts of a plurality of contacts are different from each other. The etch stop layer may be patterned to form an inner lens on the photoelectric conversion region and an etch stop layer pattern on a transistor region of the substrate. Apparatus for sealing tear tape to packaging material comprises an ultrasonic transducer and an anvil roll, the anvil roll having indicia representative of information formed in relief on the surface thereof and aligned with the path of the tear tape for embossing the indicia thereon. A diagnostic or therapeutic procedure is then performed on the joint while maintaining the joint in the flexed and distracted position.
