Abstract: An airflow sensor including a micro-heater having a film structure, which can reduce a warpage of the film structure even when a thick ness of the film structure to improve a mechanical strength thereof. An airflow sensor is provided with a monocrystalline silicon substrate having a hollow portion therein; a thin film heater portion as a micro-heater arranged above the hollow portion; and a temperature sensor. The thin film heater portion has a laminated structure of a lower thin film, a heater layer, and an upper thin film. The lower and the upper thin film respectively have a tensile stress film and a compressive stress film laminated with the tensile stress film, and are symmetry laminated with respect to the heater layer. The tensile stress film is made up of a Si3N4 film having a great moisture-proof characteristic; and the compressive stress film is made up of a SiO2 film having a great adhesion. Since these stress films cancel their internal stress each other, the internal stress can be released, and a warpage moment can be cancelled so that a warpage of the whole film structure can be restricted. Therefore, the mechanical strength can be improved even if the thickness of the film is increased.

Abstract: A mechanism for reducing stiction in a MEMS device by decreasing an amount of carbon from TEOS-based silicon oxide films that can accumulate on polysilicon surfaces during fabrication is provided. A carbon barrier material film is deposited between one or more polysilicon layer in a MEMS device and the TEOS-based silicon oxide layer. This barrier material blocks diffusion of carbon into the polysilicon, thereby reducing accumulation of carbon on the polysilicon surfaces. By reducing the accumulation of carbon, the opportunity for stiction due to the presence of the carbon is similarly reduced.
