    摘要: The present invention discloses a rapid method of restriction mapping, sequencing or localizing genetic features in a segment of deoxyribonucleic acid (DNA) that is up to 42 kb in size. The method in part comprises cloning of the DNA segment in a specialized cloning vector and then isolating nested deletions in either direction in vivo by intramolecular transposition into the cloned DNA. A plasmid has been prepared and disclosed.

    摘要: An FET structure on a semiconductor substrate which includes forming recesses for a source and a drain of the gate structure on a semiconductor substrate, halo implanting regions through the bottom of the source and drain recesses, the halo implanted regions being underneath the gate stack, implanting junction butting at the bottom of the source and drain recesses, and filling the source and drain recesses with a doped epitaxial material. In exemplary embodiments, the semiconductor substrate is a semiconductor on insulator substrate including a semiconductor layer on a buried oxide layer. In exemplary embodiments, the junction butting and halo implanted regions are in contact with the buried oxide layer. In other exemplary embodiments, there is no junction butting. In exemplary embodiments, halo implants implanted to a lower part of the FET body underneath the gate structure provide higher doping level in lower part of the FET body to reduce body resistance, without interfering with FET threshold voltage.
