Improvement of the homogeneity of high mobility In2O3:H films by sputtering through a mesh electrode studied by Monte Carlo simulation and thin film analysis.
physica status solidi (a)
Hydrogen doped Indium oxide (IOH) is a transparent conductive oxide offering great potential to optoelectronic applications. Because of its high mobility of over 100 cm2/Vs, high optical transparency in the near infra red spectrum and a low electrical resistivity of approx. 300 µΩcm can be achieved.
We have simulated the RF-sputtering deposition process of IOH by Particle-In-Cell Monte-Carlo simulation. At the surface of ceramic sputtering targets, negatively charged oxygen ions are created.…Hydrogen doped Indium oxide (IOH) is a transparent conductive oxide offering great potential to optoelectronic applications.

We have simulated the RF-sputtering deposition process of IOH by Particle-In-Cell Monte-Carlo simulation. At the surface of ceramic sputtering targets, negatively charged oxygen ions are created. These ions are accelerated towards the substrate in the plasma sheath with energies up to 150 eV. Particle energies in this order of magnitude damage the growing film, reduce crystallinity and should be avoided in order to achieve good material properties. The influence of a negatively biased mesh inside the sputtering chamber on particle energies and distributions has been calculated. We found that the mesh decreased the high energetic oxygen ion density at the substrate, thus enabling a more homogeneous IOH film growth with enhanced electrical properties. The theoretical results have been verified by XRD, 4-point-probe and hall measurements of statically depositedAndere Autor:innen -
