Abstract
First elongated loop-shaped conductive material portions are formed over a substrate. A two-dimensional array of memory pillar structures is formed over the first elongated loop-shaped conductive material portions. Second elongated loop-shaped conductive material portions over the two-dimensional array of memory pillar structures. Each of the elongated loop-shaped conductive material potions includes a respective pair of line segments and a respective pair of end segments adjoined to ends of the respective pair of line segments. A moat trench that at least partially laterally encloses the two-dimensional array of memory pillar structures can be formed by performing an anisotropic etch process that removes parts of the first and second elongated loop-shaped conductive material portions, thereby separating each loop-shaped conductive material portion into two disjoined line segments.
