A method of fabricating an LDMOS transistor and a conventional CMOS transistor together on a substrate. The trehalose click polymers of the present invention provide increased stability in serum as compared with other non-viral vectors, and are particularly useful in protecting nucleic acids against degradation. The image data fragments are stored in different hardware devices, and a fragment table that comprises pointers from one image data fragment to locations of additional data image fragments is maintained. The package sheet has a surface, on which the base end of the tape is fixed, the surface being smoothed by a smoothing process.
