Silicon Nitride Wet Etching Baths with Optimal Control ...

Silicon nitride is used as a mask on silicon wafers and further manufacturing process steps requires that the silicon nitride be removed. A solution that contains phosphoric acid and de-ionized water etches the silicon nitride with minimal oxide etch while leaving the rest of the wafer unaffected. As a result, the silicon nitride is effectively ...
