Title (EN) HIGH OVER-PRESSURE CAPABLE SILICON DIE PRESSURE SENSOR WITH EXTENDED PRESSURE SIGNAL OUTPUT
(FR) CAPTEUR DE PRESSION DE PUCE DE SILICIUM APTE À UNE SURPRESSION ÉLEVÉE, À SORTIE DE SIGNAL DE PRESSION ÉTENDUE
Abstract:
(EN) A pressure sensor (200) includes a base (203) having a high-pressure contact portion (205, 207), and a diaphragm (202) positioned over the base (203) and having an external top surface (218) opposite the base (203). The external top surface (218) is defined within a closed perimeter and external side surfaces (206, 208) extend down from an entirety of the closed perimeter toward the base (203). A high-pressure contact portion of the diaphragm (202) is aligned with and separated by a gap from the high-pressure contact portion of the base. A sensing element is coupled to the diaphragm and provides an output based on changes to the diaphragm. When a hydrostatic pressure load above a threshold value is applied to the entire external top surface (218) and external side surfaces (206, 208) of the diaphragm (202), the hydrostatic pressure load causes the high-pressure contact portion of the diaphragm to contact the high-pressure contact portion of the base.
(FR) L'invention concerne un capteur de pression (200) qui comprend une base (203) ayant une partie de contact à haute pression (205, 207), et un diaphragme (202) positionné au-dessus de la base (203) et ayant une surface supérieure externe (218) à l'opposé de la base (203). La surface supérieure externe (218) est délimitée à l'intérieur d'un périmètre fermé et des surfaces latérales externes (206, 208) s'étendent vers le bas à partir de la totalité du périmètre fermé vers la base (203). Une partie de contact à haute pression du diaphragme (202) est alignée avec, et séparée par un intervalle, de la partie de contact à haute pression de la base. Un élément de détection est couplé au diaphragme et produit une sortie basée sur des modifications apportées au diaphragme. Lorsqu'une charge de pression hydrostatique dépassant une valeur seuil est appliquée sur toute la surface supérieure externe (218) et sur des surfaces latérales externes (206, 208) du diaphragme (202), la charge de pression hydrostatique amène la partie de contact à haute pression du diaphragme à entrer en contact avec la partie de contact à haute pression de la base.
