The illustrative embodiments described herein provide systems and methods for conducting transactions with a customer using text messages. The semiconductor device has an embedded interconnect structure in which an electric conductor, such as copper or silver, is embedded in fine recesses formed in a surface of a semiconductor substrate, and also has a protective film formed on surfaces of exposed interconnects that define the interconnect structure, to protect the interconnects. In one embodiment, a charge modulation network in the SOI chip between the first power domain and the second power domain mitigates accumulation of electrical charge in an electrically isolated region of the SOI chip. Another embodiment can be used to control fermentation of the toddy drink to produce a sweet organic hard drink.
