The black silicon method: a universal method for determining the parameter setting of a fluorine-based reactive ion etcher in deep silicon trench etching with profile control [PDF]
, 1994 Very deep trenches (up to 200 µm) with high aspect ratios (up to 10) in silicon and polymers are etched using a fluorine-based plasma (SF6/O2/CHF3). Isotropic, positively and negatively (i.e.

Advanced Science, EarlyView.Magnesium silicide (Mg2Si) is introduced as a narrow‐bandgap, biodegradable semiconductor for transient electronics. RF‐sputtered and annealed Mg2Si thin films show high intrinsic electrical conductivity and low thermal conductivity. The polycrystalline material undergoes hydrolysis in aquatic and composting environments with minimal cytotoxicity ...

Quantum Hydrodynamic Model for the enhanced moments of Inertia of molecules in Helium Nanodroplets: Application to SF$_6$ [PDF]
, 2001 The increase in moment of inertia of SF$_6$ in helium nanodroplets is calculated using the quantum hydrodynamic approach. This required an extension of the numerical solution to the hydrodynamic equation to three explicit dimensions.

Advanced Science, EarlyView.A DUV‐VCSEL strategy featuring the nanometer‐class control of the cavity length is proposed in the DUV optoelectronic framework based on GaN templates. After the sapphire removal, a self‐terminated etching technology is developed, whereby the cavity length can be accurately determined by epitaxy instead of the fabrication process. As such, a record low

Diffusion principles of SF6 tracer gas: constraints on SF6 mixing distance in mine tunnels
Scientific ReportsMine wind measurement work is an important task to ensure the normal operation of mine production and environmental safety. The traditional wind measurement method uses the average wind speed and average cross-sectional area of the tunnel to calculate ...

Investigation of insulation properties and synergistic effects in CF3I/N2 gas mixtures using the Boltzmann equation [PDF]
AIP AdvancesCF3I is regarded as a highly promising substitute for SF6; however, due to its high boiling point, buffer gases such as N2 must be blended. To evaluate the feasibility of replacing SF6 and its mixtures with CF3I/N2, a comparative analysis was conducted ...

The late-time development of the Richtmyer–Meshkov instability [PDF]
, 2000 Measurements have been made of the growth by the Richtmyer–Meshkov instability of nominally single-scale perturbations on an air/sulfur hexafluoride (SF6) interface in a large shock tube.

Advanced Intelligent Systems, EarlyView.A charge‐domain ternary content‐addressable memory using one capacitor one nanoelectromechanical memory switch (1C‐1N TCAM) is proposed for energy‐efficient, high‐reliability computations. Integrated with the back‐end‐of‐line process, the 1C‐1N TCAM leverages the air gap capacitance to achieve a high capacitance ratio and ternary functionality.

Majalah Ilmiah Teknologi Elektro, 2009 Almost all of modern gas insulated switchgears (GIS) use sulphur hexafluoride (SF6) as insulation material. Therefore, GIS quality much or less depends on quality of its SF6. Failure however can arise within operation of SF6 GIS due to quality decline of
