SILICON BASED MEMBRANES

We specialize in developing and manufacturing silicon-based membranes.  We use proprietary etching methods, along with the latest in MEMS and thin-film processing, to fabricate freely suspended silicon membranes.  


Our silicon membranes are available through our standard products and through Custom Fabrication Services.  Please contact us to discuss your particular needs and applications.   

We offer a range of materials that suit many biomedical and material science applications.
