A method for the evaluative analysis of a photovoltaic layer system is described. A yoke is pivotally connected to the frame and is operatively connected to the cylinder for selectively pivoting the cylinder between a first position in which the longitudinal bore is aligned with the firing bore, and a second position in which the longitudinal bore is not aligned with the firing bore. A protected window structure includes a window structure and a panel of solidified compressible foam material disposed over at least a portion of one or more glass panes of the window structure. The output of the AND gate is applied to an exclusive-OR gate along with the Q output of the flip-flop. The nut is thereby flared capturing the sheet between flared edges of the nut and a nut flange. The semiconductor device according to the invention facilitates improving the moisture resistance of the portion of the barrier metal laminate exposed temporarily in the manufacturing process, facilitates employing only one passivation film, facilitates preventing the failures caused by cracks from occurring and the failures caused by Si nodules remaining in the aluminum alloy from increasing.
