Ceramic Discs for Semiconductor and Liquid Crystal Manufacturing Machines
Manufacturing machines parts of semiconductors need to have features of high rigidity, processing accuracy, seismic capacity, heat resistance, heat conductivity efficiency, surface processing accuracy, metal contamination, chemical resistance, gas resistance, plasma resistance, insulation performance, electric permittivity, dielectric loss tangent, volume resistivity, low dust generation (particles), cost, etc.
Nishimura Advanced Ceramics proposes applying highly-pure Alumina (Al2O3 purity 99.5% or more), Aluminum Nitride (ALN), and Yttria (Y203), as those ceramics satisfying the above requirements.
Because of its features, those materials are used as a transfer arm, wafer stages, and so on. Those materials are also good compatibility with metallization.
Aluminum nitride is excellent in heat conductivity, heat radiation, heat shock resistance, and electrical insulation. Furthermore, its thermal expansion coefficient is similar to a silicon wafer.
Yttria is the material which has excellent plasma resistance.
