Abstract

Un conjunto inventivo (300) de espejos (301) accionados de película delgada M x N incluye una matriz activa (210), una capa aislante (220), una capa de frenado de reactivo para ataque (230) y un conjunto de estructuras de accionamiento M x N (200). Cada una de las estructuras de accionamiento tiene una punta en un extremo distante del mismo y una apertura del reactivo para ataques atravesando al mismo y además incluye un primer electrodo de película delgada (285) con una cinta horizontal, un miembro electrodiplacivo de película delgada (275), un segundo electrodo de película delgada (265), un miembro elástico (225) y un conducto (295). La cinta horizontal (285), la punta y la apertura del reactivo para ataque se crean con el fin de aumentar la eficiencia optica de cada uno de los espejos accionados de película delgada, facilitar la extraccion del enjuague y permitir una extraccion fácil de la capa sacrificial de la película delgada respectivamente.
