Stoichiometric (High Q-Factor) Silicon Nitride Membranes:

Norcada manufactures stoichiometric Silicon Nitride Membrane devices primarily for researchers who are interested in studying quantum behavior of cavity optomechanical systems using Si3N4 membranes with high mechanical quality factor (High-Q) at very low temperatures.  Our NX series stoichiometric Si3N4 membrane windows are fabricated on 200um thickness silicon frame.  Our QX series come with 500um thick silicon frame.  All of the stoichiometric membrane windows are made from Si3N4 films with 1.0GPa high tensile stress.
