Patent number: 7521369Abstract: A method is disclosed for the selective removal of rare earth based high-k materials such as rare earth scandate high-k materials (e.g. DyScO3) over silicon or silicon dioxide. As an example Dy and Sc comprising high-k materials are used as a high-k material in gate stacks of a semiconductor device. The selective removal and etch of this high-k material is very difficult since Dy and Sc (and their oxides) are difficult to etch. The etching could however be easily stopped on them. For patterning of the metal gates comprising TiN and TaN on top of rare earth based high-k layer a chlorine-containing gases (Cl2 and BCl3) can be used since titanium ant tantalum chlorides are volatile and reasonable selectivity to other material present on the wafer (Si, SiO2) can be obtained. The Dy and Sc chlorides are not volatile, but they are water soluble.Type: GrantFiled: October 22, 2007Date of Patent: April 21, 2009Assignee: Interuniversitair Microelektronica Centrum (IMEC)Inventors: Denis Shamiryan, Marc Demand, Vasile Paraschiv
