For the substrate injection case, electron trapping in the bulk of the Al/sub 2/O/sub 3/ films dominates, whereas hole trap near the Si substrate is observed for gate injection. This asymmetry in defect creation causes an asymmetry in oxide reliability. For gate injection, reliability is limited by the thin SiO/sub 2/ interfacial layer, yielding low beta values, independent of the Al/sub 2/O/sub 3/ thickness. For substrate injection, reliability is limited by electron trap generation in the bulk of the Al/sub 2/O/sub 3/ film, yielding a strong thickness dependence of the beta values, as expected from the percolation model and as observed in SiO/sub 2/ layers of similar thickness.","PeriodicalId":103040,"journal":{"name":"2002 Symposium on VLSI Technology.

The explanation for this C/sub inv/ lowering is as follows: (1) the gate length becoming shorter than the poly-grain size (R/sub G/) and (2) the short dopant-diffusion length from grain boundaries (D/sub H/). Techniques for achieving small values for R/sub G/ and large values for D/sub H/ improved the I/sub D/ figures by +15% for the pFET and by +3% for the nFET that have poly-SiGe gates with L/sub G/=65 nm.","PeriodicalId":103040,"journal":{"name":"2002 Symposium on VLSI Technology.

For the process optimization required for the technologies of sub-50 nm MOSFETs, we investigated the issues of LTP and cleared them up. S/D-extension (SDE)-junction depth, overlap and sheet resistance were controlled by pre-amorphization ion implantation (I/I) energies, and the first two parameters could be thus controlled regardless of dopant dose. This enabled us to design highly activated and abrupt box-like dopant profiles without inducing any short channel deterioration. With this technique, we achieved higher drive current pMOSFETs for the same V/sub th/-rolloff and a 13% improvement in drivability for 45 nm pMOSFETs.","PeriodicalId":103040,"journal":{"name":"2002 Symposium on VLSI Technology.
