HF-(NH4)2S2O8-HCl Mixtures for HNO3- and NOx-free Etching of Diamond Wire- and SiC-Slurry-Sawn Silicon Wafers: Reactivity Studies, Surface Chemistry, and Unexpected Pyramidal Surface Morphologies

Autor: André Stapf, Edwin Kroke, Christoph Gondek, Marcus Lippold

Publikováno v: ACS Applied Materials & Interfaces. 7:8733-8742

The wet-chemical treatment of silicon wafers is an important production step in photovoltaic and semiconductor industries. Solutions containing hydrofluoric acid, ammonium peroxodisulfate, and hydrochloric acid were investigated as novel acidic, NOx-

Texturing of SiC-slurry and diamond wire sawn silicon wafers by HF–HNO3–H2SO4 mixtures

Autor: Florian Buchholz, Edwin Kroke, Florian Honeit, Marcus Lippold, Eckard Wefringhaus, Christoph Gondek

Publikováno v: Solar Energy Materials and Solar Cells. 127:104-110

The reactivity of HF(40 wt%)–HNO3(100 wt%)–H2SO4(97 wt%) etching mixtures towards conventional SiC-slurry and diamond-wire sawn silicon wafers has been studied. Sulfuric acid-rich mixtures exhibit adequate etching rates (r

HF-HNO3-H2SO4/H2O Mixtures for Etching Multicrystalline Silicon Surfaces: Formation of NO2 +, Reaction Rates and Surface Morphologies

Autor: Marcus Lippold, Edwin Kroke, Sebastian Patzig-Klein

Publikováno v: Zeitschrift für Naturforschung B. 66:155-163

The reaction behavior of HF-HNO3-H2O etching mixtures, which are frequently used for texturing silicon surfaces, is significantly influenced by the addition of sulfuric acid. For high concentrations of sulfuric acid, nitronium ions NO2 + ions have be
