MEMS中Ni-W合金薄膜力学性能的研究
Study on mechanical properties of Ni-W alloy films in micro-electro-mechanical system
【摘要】 研究了柠檬酸胺—1—羟基乙烷二膦酸(HEDP)镀液体系中Ni-W的力学性能。通过紫外曝光的光刻、电铸和注塑(UV-LIGA)技术制备出微拉伸试样和单轴微拉伸测试系统进行拉伸试验。结果表明:在Ni-W薄膜试样尺寸为5μm×50μm×100μm条件下,其杨氏模量约为100.4 GPa,抗拉强度为1.96 GPa,应变约为3.6%。
【Abstract】 The mechanical properties of Ni-W alloy films electrodeposited in the system of citrate amine-HEDP are sdudied.The testing chip is fabricated with UV-LIGA technology and measured by uniaxial micro-tensile system.The gauge section of Ni-W thin film specimen is 5μm×50μm×100μm.The results show that the Young’s modulus of Ni-W film is about 100.4GPa,tensile strength is about 1.96GPa and strain is about 3.6%,respectively.
