This product consist of 100mm silicon wafers with 2,000A of Stoichiometric LPCVD Nitride.
Our Stoichiometric LPCVD Nitride can be a very effective insulator and works great as a KOH etch mask when deposited over thermal oxide. This versatile film can be used for building MEMS devices or as a tool for defining active regions during field oxidation. As with all of our films, we have worked hard to develop a stable and consistent Stoichiometric LPCVD Nitride process that can be used for many applications.
