摘要: A hard mask etch stop is formed on the top surface of tall fins to preserve fin height and protect from damage during etching steps transistor fabrication process. In an embodiment, using a dual system, wherein layer over substrate, second used pattern with fin. The removed, while remains subsequent steps.
