Performance of a non-volatile semiconductor storage device which performs electron writing by hot electrons and hole erasure by hot holes is improved. The touch signal accessing method of the touch device includes the following steps. Solder balls disposed between the first solder ball contact array pattern of the optical device substrate and the second solder ball contact array pattern are melted so that solder reflow self-aligns the patterns, and further positions the optical device array in a predetermined orientation with respect to the alignment holes in the carrier. DDM-HCAs of the invention are soluble HCA-containing compositions useful as dietary supplements and suitable for manipulations under those conditions necessary for tabletting, encapsulation, and the production of dry powders, particularly for use as a beverage premix. The IP packets can also be modulated using a pseudonoise spreading code.
