2019 Symposium on VLSI Technology.
Superconducting parametric amplifier, originally developed more than half a century ago, gained renewed interests in some experiments of superconducting quantum electronics about a decade ago, and now has become an indispensable tool in the field of

Sub-10-nm planar bulk CMOS devices were demonstrated by a lateral source/drain (S/D) junction control, which consists of the notched gate electrode, shallow S/D extensions, and steep halo in a reverse-order S/D formation. Furthermore, the transport p

We have developed a low-leakage and highly reliable 1.5-nm SiON gate-dielectric by using radical oxygen and nitrogen. In this development, we introduce a new method for determining an ultrathin SiON gate-dielectric thickness based on the threshold vo

We report the importance of oxynitridation using radical-oxygen and -nitrogen to form a low-leakage and highly reliable 1.6-nm SiON gate-dielectric without performance degradation in n/pFETs. It was found that oxidation using radical-oxygen forms hig

We have demonstrated that oxynitridation using radical-oxygen (radical-O) and radical-nitrogen (radical-N) improves reverse narrow channel effects (RNCE) and reliability in sub-1.5-nm-thick gate-SiO/sub 2/ FETs with narrow channel and shallow-trench

Advanced tungsten/pn-poly-Si gate CMOS devices with an ultralow sheet resistance of 1 /spl Omega//sq. have been demonstrated using an amorphous-Si/TiN buffer layer. A low-resistivity tungsten film is formed by large grain size tungsten on an amorphou

The bias temperature instability in surface-channel p/sup +/ polysilicon gate p-MOSFETs was evaluated. It was found that a large negative threshold voltage shift (/spl Delta/V/sub th,BT/) is induced by negative bias temperature (BT) stress in short-c

Nanometer electron beam lithography has been used for fabrication of sub-0.1 μm MOSFETs. Chemically amplified resist as a single layer mask showed high resolution by optimizing the resist process. Proximity effect correction was applied and showed a

A nanometer electron beam lithography system has been developed and used for fabricating sub-0.1μm gate MOSFETs. The system uses a Zr/O/W thermal field emitter (TFE) and has a 5-nm- diameter beam at a current of 100pA, and an acceleration voltage of
