    Abstract: A piezo-TFT cantilever microelectromechanical system (MEMS) and associated fabrication processes are provided. The method comprises: providing a substrate, such as glass for example; forming thin-films overlying the substrate; forming a thin-film cantilever beam; and simultaneously forming a TFT within the cantilever beam. The TFT is can be formed least partially overlying a cantilever beam top surface, at least partially overlying a cantilever beam bottom surface, or embedded within the cantilever beam. In one example, forming thin-films on the substrate includes: selectively forming a first layer with a first stress level; selectively forming a first active Si region overlying the first layer; and selectively forming a second layer overlying the first layer with a second stress level. The thin-film cantilever beam is formed from the first and second layers, while the TFT source/drain (S/D) and channel regions are formed from the first active Si region.

    Abstract: A micromechanical sensor and a method for manufacturing same are described. A secure diaphragm restraint, independent of fluctuations in the cavern etching process due to the process technology, and a free design of the diaphragm are made possible by designing a suitable connection of the diaphragm in an oxide layer created by local oxidation. The micromechanical sensor includes, for example, a substrate, an external oxide layer formed in a laterally external area in the substrate, a diaphragm having multiple perforation holes formed in a laterally internal diaphragm area, a cavern etched in the substrate beneath the diaphragm, whereby the diaphragm is suspended in a suspension area of the external oxide layer which tapers toward connecting points of the diaphragm and the diaphragm is situated in its vertical height between a top side and a bottom side of the external oxide layer.

    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.
