Eco-Friendly Chemical-Free Etching for Semiconductor and Glass Component Production

manufacturingPrototypeTRL 3

Imagine carving tiny, precise patterns into silicon or glass, but instead of using harsh, toxic acids that harm the planet, you use a clean plasma 'sandblaster'. It's like switching from a chemical paint stripper to a high-tech laser cleaner. This method removes the need for dangerous halogens while using less electricity to get the job done.
