Title (EN) TRAPPED MEMBRANE
(FR) MEMBRANE PIÉGÉE
Abstract:
(EN) A MEMS trapped membrane. The MEMS trapped membrane includes a first layer and a second structure. The first layer has an outer section and an inner membrane. The outer section and inner membrane are detached from each other by a separation, and have inner membrane protrusions and outer section protrusions formed by the separation. The second structure is coupled to the outer section and has second protrusions that overlay corresponding inner membrane protrusions.
(FR) L'invention concerne une membrane MEMS piégée incluant une première couche et une seconde structure. La première couche a une section externe et une membrane interne. La section externe et la membrane interne sont détachées l'une de l'autre par une séparation, et comportent des protubérances de membrane interne et des protubérances de section externe formées par la séparation. La seconde structure est couplée à la section externe et a des secondes protubérances qui recouvrent des protubérances de membrane interne correspondantes.
