Wet Bench

Wet etching is a technique for removing materials. This is achieved by immersing the sample into a specific liquid. The chemical constituents of the liquid reacts with specific elements in the sample producing a compound that dissolves away. This technique can be combined with an etch resistant masking material to etch patterns into the sample.

Fume Hoods

Wet etching is performed inside of a fume hood to protect the researchers from potentially hazardous fumes. Each of the 5 fume hoods in the lab are dedicated to specific processes to avoid cross contamination and improve safety.
