Wet chemical etching mechanism of silicon [PDF]

open access: yesProceedings IEEE Micro Electro Mechanical Systems An Investigation of Micro Structures, Sensors, Actuators, Machines and Robotic Systems, 2002
We review what can be said on wet chemical etching of single crystals from the viewpoint of the science of crystal growth. Starting point is that there are smooth and rough crystal surfaces. The kinetics of smooth faces is controlled by a nucleation barrier that is absent on rough faces. The latter therefore etch faster by orders of magnitude.

Simulation of convection-driven wet-chemical etching [PDF]

open access: yes, 2022
In a wet-chemical etching process, the resulting etched shape is smaller than the originally designed shape at the mask. This is caused by the fact that, as soon as material next to the mask is dissolved, material under the mask will be dissolved too. This is the so-called undercut effect.

Transmittance modulation by gold nanoparticle mediated wet chemical etching of silica [PDF]

open access: yes, 2023
Wet etching in hydrofluoric acid (HF) is one of the most common routes for the surface texturing of silica, leading to improved optical properties, which find applications in several fields.

Wet chemical etching survey of III-nitrides [PDF]

open access: yesSolid-State Electronics, 1997
AbstractWet chemical etching of GaN, InN, AIN, InAlN and InGaN was investigated in various acid and base solutions at temperatures up to 75°C. Only KOH-based solutions were found to etch AIN and InAlN. No etchants were found for the other nitrides, emphasizing their extreme lack of chemical reactivity.

Investigation of the Integration of Strained Ge Channel with Si-Based FinFETs

open access: yesNanomaterials, 2022
In this manuscript, the integration of a strained Ge channel with Si-based FinFETs was investigated. The main focus was the preparation of high-aspect-ratio (AR) fin structures, appropriate etching topography and the growth of germanium (Ge) as a channel

Femtosecond-Laser-Induced All-Silicon Dielectric Metasurfaces Assisted by Wet Chemical Etching

open access: yesUltrafast Science, 2023
All-dielectric metasurfaces offer low material loss and strong field localization and are, therefore, well suited for ultrathin and compact optical devices for electomagnetic wave manipulation at the nanoscale.

Surface improvement of laser powder bed fusion processed Ti6Al4V for fatigue applications

open access: yesAdditive Manufacturing Letters, 2022
Laser Powder Bed Fusion holds significant potential for the manufacturing of highly complex Ti6Al4V structural components, however the as-produced surface roughness severely limits the fatigue life of components.
