    摘要: A method includes forming a dummy gate in a dielectric layer on a substrate, the dummy gate including a sacrificial oxide layer and a dummy gate body over the sacrificial oxide layer; removing the dummy gate body resulting in a gate opening with the sacrificial oxide layer in a bottom of the gate opening; performing an off-axis sputtering to create an angled entrance on the gate opening; removing the sacrificial oxide layer; and forming a replacement gate in the gate opening.

    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.
