Microstructure and etching properties of sputtered indium—tin oxide (ITO)

Abstract: Indium—tin oxide (ITO) applied to optoelectronic devices must meet several requirements simultaneously, i.e. electrical conductivity, optical transparency, and structurability by photolithography. As will be shown, these properties are mainly based on the microstructure of the ITO films. The microstructure changes from amorphous to polycrystalline depending on the oxygen partial pressure in the sputtering ambient and the deposition rate. We investigated the influence of an oxide layer on the target surface, it… Show more

“…[10][11][12][13][14][15] The etching property of ITO has also been investigated. 13,[16][17][18][19][20][21] The etching rate is enhanced when the microstructure of ITO consists of grains embedded in an amorphous matrix. 16) However, the amorphous ITO films were difficult to prepare by magnetron sputtering, so they were prepared by ion beam sputtering.…”

“…19,20 The oxygen flow rate is constant during a sputtering process. The balance between the amount of sputtered particles and oxygen depends on the sputtering rate, which slightly shifts into the oxygen-rich condition as the deposition time increases.…”

“…К таким методам относятся химическое (chemical liftoff) [10,11] и лазерное отделение (laser lift-off) [12][13][14][15][16]. Метод химического отделения позволяет отслаивать пленки ITO без механического повреждения, но требует создания промежуточного слоя на ростовой подложке и дополнительного отжига после отделения, что влияет на качество пленок ITO.…”
