  • Production of a semiconductor device having at least one column-shaped or wall-shaped semiconductor element
    Patent number: 9184235
    Abstract: Described is a method for producing a semiconductor device (100), in which at least one column-shaped or wall-shaped semiconductor device (10, 20) extending in a main direction (z) is formed on a substrate (30), wherein at least two sections (11, 13, 21, 23) of a first crystal type and one section (12, 22) of a second crystal type therebetween are formed in an active region (40), each section with a respective predetermined height (h1, h2), wherein the first and second crystal types have different lattice constants and each of the sections of the first crystal type has a lattice strain which depends on the lattice constants in the section of the second crystal type.
