Abstract
The invention is a method of introducing porous membranes into MEMS elements by supporting the membranes by frames to form an heterostructure. This is achieved by attaching to a structured or porous substrate one or more monolithically fabricated frames and membranes. Having membranes disposed on frames enables them to be batch processed and facilitates separation, handling and mounting within MEMS or nanofluidic systems. Applications include, but are not limited to, filters for gases or liquids, electron transmissive windows and scanning electron microscopy (SEM) accessible arrays of nanotest tubes containing liquid phases and other sample states. The invention includes the apparatus made by the method.
