    摘要: A method in the fabrication of a semiconductor device simultaneously forms different patterns on the same level of the device. The device has a first area and a second area. A low density mask pattern of at least one relatively wide topographic feature is formed on the second area, a plurality of relatively narrow topographic features is formed on the first area, first spacers are formed on side walls of the narrow topographic features in the first area, the relatively narrow topographic features are removed, and the patterns of the first spacers and the relatively wide topographic feature(s) are simultaneously transcribed in the first and second areas, respectively.
