    Abstract: A patterning method is disclosed. A substrate having a hard mask layer and a first material layer formed thereon is provided. The first material layer is patterned into first array patterns and first peripheral patterns. The first array patterns are further transferred into first spacer patterns. Subsequently, a planarization layer and a second material layer are successively formed on the substrate. The second material layer is patterned into second array patterns and second peripheral patterns. The second array patterns are further transferred into second spacer patterns. The second spacer patterns partially overlap the first spacer patterns. The second peripheral patterns do not overlap the first peripheral pattern. The first spacer patterns not overlapped by the second spacer patterns are removed to obtain third array patterns. The hard mask layer is then etched using the third array patterns, the second peripheral patterns and the first peripheral patterns as an etching mask.

    Abstract: A method of fabricating a mask includes providing a substrate. A first material layer is disposed on the substrate. Then, the first material layer is partly removed. A second trench is formed between the remaining first material layer. The second trench includes a height. Later, a second material layer is formed to conformally fill in the second trench. The second material layer includes a thickness. The thickness of the second material layer equals the height of the second trench. Finally, part of the second material layer is removed, and the remaining second material layer and the remaining first material layer comprise a second mask.

    Abstract: A semiconductor device has a 6T SRAM cell formed on a substrate. The SRAM cell includes a first and a second PMOS transistors formed over an N-well line in a substrate. A first and a second NMOS transistors are formed over a first P-well line in the substrate at a first side of the N-well line. A third and a fourth NMOS transistors are formed over a second P-well line in the substrate at a second side of the N-well line. A first gate line connects gates of the first PMOS transistor and the first NMOS transistor. A second gate line connects a gate of the second NMOS transistor. A third gate line connects gates of the second PMOS transistor and the third NMOS transistor. A fourth gate line connects a gate of the fourth NMOS transistor. The first gate line and the third gate line are in L-shape.
