Tin oxide etching
WebIndium tin oxide (ITO) is a material that is widely used in displays and optoelectronic devices because it is transparent and conducts electricity well [ [1], [2], [3] ]. To make ITO devices, etching, deposition, etc. are used. In particular, etching is one of the important processes, as it greatly affects the properties of ITO [ 4, 5 ]. WebJan 3, 2000 · Platinum thin films have been successfully patterned without fence residues using an Ar/O 2 helicon wave plasma. Photoresist and silicon oxide masks were also studied for comparison. The etch rate of the TiN mask decreases, but the etch slope increases with an increase of the oxygen concentration in the Ar/O 2 gas mixture. An etch rate of about …
