Single, double and surround gate vertical MOSFETs with reduced parasitic capacitance [PDF]

, 2004
The vertical MOSFET structure is one of the solutions for reducing the channel length of transistors under 50nm. Surround gates can be easily realised in vertical MOSFETs which offer increased channel width per unit silicon area.

Vertical MOSFETs for high performance, low cost CMOS [PDF]

, 2007
-We present a review of recent reports on vertical MOSFETs which includes a summary of our own research in this area. Such devices can offer a decananometer channel length in a relaxed lithography. Furthermore, the footprint is substantially smaller than

Research on the relationship between architectural features in northeast China and vertical aerosol transmission of COVID-19

Frontiers in Public Health, 2023
During the COVID-19 pandemic, many buildings in northeast China have had clusters of infected cases in the vertical layout. There is speculation that vertical aerosol transmission occurs. The houses in northeast China are airtight, and range hoods may be

Three-dimensional consolidation theory of vertical drain based on continuous drainage boundary

Journal of Civil Engineering and Management, 2019
To remedy the limitation that the conventional drainage boundary only considers two extreme cases of pervious and impervious boundaries, the consolidation theory of vertical drain is derived by applying the continuous drainage boundary, and its validity ...

Consolidation theory of soft foundation with partially penetrating vertical drains under surcharge-vacuum preloading

Yantu gongcheng xuebao, 2022
Due to the limitations of the existing methods, a simplified method for calculating the consolidation degree for the soft foundation with partially penetrating vertical drains is devised, in which the soil is divided into two layers: an upper layer with ...
