Patterning Sub-30-nm MOSFET Gate with -Line Lithography

We have investigated two process techniques: resist ashing and oxide hard mask trimming. A combination of ashing and trimming produces sub-30-nm MOSFET gate. These techniques require neither specific equipment nor materials. These can be used to fabricate experimental devices with line width beyond the limit of optical lithography or high-throughput -beam lithography. They provide 25-nm gate pa...

Sub-30 nm InAs Quantum-Well MOSFETs with Self-Aligned Metal Contacts and Sub-1 nm EOT HfO2 Insulator

Sub-30 nm III-V planar Quantum-Well (QW) n-type MOSFETs are fabricated through a self-aligned CMOS compatible front-end process. Good performance and short-channel effect mitigation are obtained through the use of a QW-channel that incorporates a thin pure InAs subchannel and extremely scaled HfO2 gate dielectric on a very thin InP barrier (total barrier EOT<1 nm). The devices also feature self...

Metal cluster chemistry: Structure and stereochemistry in the polynuclear rhodium hydrides H_nRh_n[P(OR)₃]_2n

Crystallographic analyses of x-ray and neutron diffraction data have provided a definitive structural representation of fHRh[P(O-i-C3H7)3J2j2 and IHRhIP(OCH3)31213. These polynuclear hydrides are generated from square planar H2RhIP(OR)3J2 units by edge (hydrogen atom) sharing and by vertex (hydrogen atom) sharing to form the dimeric and trimeric structures, respectively. The square-planar units...

Synthesis and Characterization of Tb[N(CN)₂]₃·2H₂O and Eu[N(CN)₂]₃·2H₂O: Two New Luminescent Rare-Earth Dicyanamides

Two new rare-earth dicyanamides, namely, Tb[N(CN)2]3‚2H2O and Eu[N(CN)2]3‚2H2O, have been prepared by ion exchange in aqueous solution, followed by evaporation of the solvent at room temperature. The structures of both compounds have been solved and refined from single-crystal and powder X-ray diffraction data, respectively. The two compounds are isostructural and are built up from irregular qu...
