Effect of Isopropyl Alcohol Concentration and Etching Time on Wet Chemical Anisotropic Etching of Low-Resistivity Crystalline Silicon Wafer
A micropyramid structure was formed on the surface of a monocrystalline silicon wafer (100) using a wet chemical anisotropic etching technique. The main objective was to evaluate the performance of the etchant based on the silicon surface reflectance. Different isopropyl alcohol (IPA) volume concentrations (2, 4, 6, 8, and 10%) and different etching times (10, 20, 30, 40, and 50 min) were selec...
متن کاملMultiscale modeling of anisotropic wet chemical etching of crystalline silicon
– We combine ab initio and Monte Carlo simulations in multiscale modelling of anisotropic wet chemical etching of silicon. The anisotropy of the macroscopic etching patterns observed in the experiments is explained by two mechanisms at an atomistic scale: the weakening of backbonds following OH termination of surface sites and the existence of significant interaction between the surface-termina...
متن کاملAtomistic simulations of surface coverage effects in anisotropic wet chemical etching of crystalline silicon
Atomistic simulations of anisotropic wet chemical etching of crystalline silicon have been performed in order to determine the dependence of the etch rates of different crystallographic orientations on surface coverage and clustering of OH radicals. We show that the etch rate is a non-monotonic function of OH coverage and that there always exists a coverage value at which the etch rate reaches ...
متن کاملWet-Chemical Etching and Cleaning of Silicon
A Introduction Research and manufacturing related to silicon devices, circuits, and systems often relies on the wet-chemical etching of silicon wafers. The dissolution of silicon using liquid solutions is needed for deep etching and micromachining, shaping, and cleaning. Also, wet-chemistries are often used for defect delineation in single crystal silicon materials. In this paper, a review of t...
متن کاملOptical Mems Devices Based on Wet Anisotropic Etching of Silicon
Optical MEMS found various applications over the last years due to the rapidly increasing data rates in optical networks. As standard single-mode fibers are used, the required alignment tolerances are below 1 μm for optical fiber. The assembly and reliability of MOEMS devices requires increasing attention. Additionally, the trend is going from single-functionality devices to more complex subsys...
