TLDR
Based on the experimentally extracted etch rate of unimplanted and implanted silicon-dioxide, the patterning of the sacrificial layer can be predicted by simulation as discussed by the authors, which is of interest to greatly reduce the underetch of microelectromechanical system anchors.About:

Chemical purification processes of the natural crystalline flake graphite for Li-ion Battery anodes
TL;DR: In this paper, the effect of acid species, liquid-to-solid ratio, reaction time, and temperature on the carbon content (CC) of natural crystalline flake graphite in Ethiopia was investigated.

The influence of hydrofluoric acid etching processes on the photocatalytic hydrogen evolution reaction using mesoporous silicon nanoparticles.
TL;DR: The response of the photocatalytic activity of mp-Si nanoparticles to a series of HF acid treatments was investigated and it was found that morphological damage and the presence of byproducts in the pores likely result in a lowering of the H2 evolution rate.

Manufacturing Issues of BEOL CMOS-MEMS Devices
TL;DR: In this article, the main issues affecting CMOS-MEMS high-yield manufacturing regarding the silicon oxide as a sacrificial material, the passivation as a release mask, the BEOL as structural material for MEMS design and the aluminum-sputtering as a sealing layer for the MEMS cavity were identified.

Surface topography evolution and fatigue fracture in polysilicon MEMS structures
TL;DR: In this article, the initial stages of fatigue are associated with stress-assisted surface topography evolution and the thickening of SiO/sub 2/ layers that form on the unpassivated polysilicon surfaces and crack/notch faces.
