  • Patent number: 9761724
    Abstract: A method of patterning a semiconductor film is described. According to an embodiment of the present invention, a hard mask material is formed on a silicon film having a global crystal orientation wherein the semiconductor film has a first crystal plane and second crystal plane, wherein the first crystal plane is denser than the second crystal plane and wherein the hard mask is formed on the second crystal plane. Next, the hard mask and semiconductor film are patterned into a hard mask covered semiconductor structure. The hard mask covered semiconductor structured is then exposed to a wet etch process which has sufficient chemical strength to etch the second crystal plane but insufficient chemical strength to etch the first crystal plane.
