Semiconductor devices - Micro-electromechanical devices - Part 21: Test method for Poisson's ratio of thin film MEMS materials
半导体器件微机电器件第21部分:薄膜MEMS材料泊松比的试验方法
IEC 62047-21:2014 specifies the determination of Poisson's ratio from the test results obtained by the application of uniaxial and biaxial loads to thin-film micro-electromechanical systems (MEMS) materials with lengths and widths less than 10 mm and thicknesses less than 10 μm.
