WebSalt/Vinegar/Hydrogen peroxide mix is, by far, the cheapest etchant (Hydrogen peroxide 3% is 2$ for 16 oz, Vinegar is 2$ for a liter and salt is almost negligeable) with a price of less than 4$ per liter.. Ferric chloride costs around 10$ for 16 oz which is arround 20$ per liter, five times more than the first !. In terms of environmental impact "sponge technique" is, … WebPlasma etch rates on patterned wafers can be quite different from those listed here for two reasons: 1. Some plasma etch rates tend to increase when there is less surface area to be etched, due to higher etch gas concentrations. 2. Usually be etched under those conditions (e.g., oxide in the poly etcher, LAM 1). These wafers were in store insulated grocery bag
