SiO2 Etch

I am in the process of doing some development of a SiO2 etch. So far I have found this fairly good recipe. For now it is the standard SiO2 etch recipes but I might change the "Standard recipe" a a later time if I find a better one. You are welcome to contact me see more result. I will add them to Labadviser at a later time. /Berit Herstrøm bghe@dtu.dk (Nanolab)
