Semiconductor Thin Films
PVD deposition for device fabrication and advanced materials research
High-vacuum PVD systems support the deposition of metallic contacts, diffusion barriers, transparent conductors, ferroelectric, piezoelectric, and oxide semiconductor films required in microelectronics, power devices, MEMS, and photovoltaic fabrication.
Overview
Semiconductor device fabrication and advanced materials research demand thin-film deposition systems capable of achieving exceptional purity, uniformity, and stoichiometry control. HUANING ZHIKE magnetron sputtering and composite platforms provide the controlled deposition environment, multiple target materials, and substrate heating required for metallic contact layers, dielectric barriers, compound semiconductor films, and functional oxide deposition in research and pilot production contexts.
