A Brick Mason Wire Bend tool for use of adjusting the tie wire in masonry construction has the form of a bar having an intermediate bent radius section and opposite end portions which are displaced out of the plane of the intermediate section at an acute angle. The charge-trapping layer includes first and second conductive segments and a nitride segment, where the nitride segment is situated between the first and second conductive segments. The effluent gas contains residual components of the reaction gas mixture together with reaction products, including hydrogen. The PFCPWM control circuit is for modulating the primary direct current voltage. The spool further includes two end flanges and a middle flange. Thus, different regions of the silicon layer are biased by different bias signals.
