WebMicrofluidic chip fabrication techniques: Polymer ablation. It’s possible to realize the microstructures using direct writing processes such as conventional mechanical drilling, sawing, laser machine and powder blasting. These techniques have pros and cons; they allow to make micro devices really quickly and sometimes in 3D with laser. WebLithography includes a series of fabrication techniques that share the principle of transferring an image from a mask to a receiving substrate. A typical lithographic process consists of three successive steps: (i) coating a substrate (Si wafer or glass) with a sensitive polymer layer (called resist), (ii) exposing the resist bishop wand school term dates
