Abstract

Methods for producing micromachined layered devices having a membrane layer and a first and second layer on both sides of the membrane layer are disclosed. The method includes applying a membrane layer to a substrate, opening a window in the substrate so as to enable the addition of layers from both sides of the membrane layer while the substrate is made into a frame that supports the membrane layer during processing, adding at least one layer on each side of the membrane either simultaneously or on one side at a time, and removing the device from the substrate frame.
