Abstract

Esta solicitud se refiere a un microsensor resonante piezoresistivo tipo p que utiliza el principio de la fuerza de Lorentz para medir un amplio rango de campos magnéticos (1-400G) con un alto factor de calidad (Q=842) y sensibilidad magnética (40.3 V/G) operando a presion atmosférica. El objeto de esta solicitud es proporcionar una mejora de los microsensores resonantes actuales mediante la utilizacion de una configuracion estructural placa-viga optimizada de silicio de 15 m de espesor con un puente de Wheatstone mejorado con piezoresistores dopados de boro (tipo p) y una configuracion de lazo de aluminio alrededor de la estructura placa-viga, que le permiten un mejor funcionamiento global, con un mínimo de componentes estructurales.
