    • An apparatus comprising a microelectromechanical system (MEMS) device. The MEMS device includes a substrate having an anchoring pad thereon and a structural element. The structural element has a beam that includes a first part and a second part. The first part is attached to both the anchoring pad and to the second part. The second part is movable with respect to the substrate and made of an electrically conductive material. Additionally, at least one of the following conditions hold: the first part is made of a material having: a first yield stress that is greater than a second yield stress of the electrically conductive material of the second part; a fatigue resistance that is greater than a second fatigue resistance of the electrically conductive material of the second part; or, a creep rate that is less than a second creep rate of the electrically conductive material of the second part.
    • 一种包括微机电系统(MEMS)装置的装置。 MEMS器件包括其上具有锚定垫的衬底和结构元件。 结构元件具有包括第一部分和第二部分的梁。 第一部分连接到锚固垫和第二部分。 第二部分可相对于基板移动并由导电材料制成。 另外,以下条件中的至少一个成立:第一部分由具有第二部分的导电材料的第二屈服应力的第一屈服应力的材料制成; 大于第二部分的导电材料的第二耐疲劳性的耐疲劳性; 或者小于第二部分的导电材料的第二蠕变速率的蠕变速率。
