摘要
将 CMOS工艺和微机械加工技术相结合 ,制作出悬空式微桥支撑、薄膜支撑以及无悬空结构的微机械多晶硅薄膜电阻。通过对样品的电阻温度系数 ( TCR)和电流 ( I) -电压 ( V)特性的测量 ,研究了热隔离程度。
Micromachined polysilicon thin film resistors supported by microbridge and by thin film have been designed and fabr icated by CMOS process and micromachining technology. After measuring the temper ature coefficient of resistance(TCR) and I-V characteristics, the influ ence of thermal environment, such as the degree of thermal insulation and the pressure o f atmosphere, on electrical properties of these resistors is investigated and di scussed.
