Semiconductor acceleration sensor

   
   

A semiconductor acceleration sensor includesa non-single-crystal-silicon-based substrate, an insulating beam structure having a movable section and a stationary section, at least one piezoresistor positioned on the beam structure, an insulating supporter positioned on the non-single-crystal-silicon-based substrate for fixing the stationary section of the beam structure and forming a distance between the beam structure and the non-single-crystal-silicon-based substrate, and a thin film transistor (TFT) control circuit positioned on the non-single-crystal-silicon-based substrate and electrically connected to the piezoresistor and the beam structure.

Un substrat non-simple-cristal-silicium-basé par includesa de sonde d'accélération de semi-conducteur, une structure isolante de faisceau ayant une section mobile et une section stationnaire, au moins un piezoresistor placé sur la structure de faisceau, un défenseur isolant placé sur le substrat non-simple-cristal-silicium-basé pour fixer la section stationnaire de la structure de faisceau et former une distance entre la structure de faisceau et le substrat non-simple-cristal-silicium-basé, et un circuit de commande du transistor de la couche mince (TFT) placé sur le substrat non-simple-cristal-silicium-basé et électriquement relié au piezoresistor et à la structure de faisceau.
