Assembly of Silicon Nitride Channels

Fabrication of silicon based micro-channels is typically a complex process involving multiple steps such as lithography, bonding, thin film deposition, etching, surface migration etc. We present a method for the fabrication of microchannels . insired by 2D material transferring techniques, we transfer a 100 nm thick silicon nitride film on top of a silicon nitride coated chip with predefined trenches and holes to form silicon nitride microchannels and membranes.
