    摘要: Semiconductor devices and manufacturing methods thereof are disclosed. In one embodiment, a semiconductor device includes a workpiece with a first region having a plurality of first features and a second region having a plurality of second features proximate the first region. The first region and the second region share a patterning overlap region disposed between the first region and the second region. The patterning overlap region includes a residue feature with an aspect ratio of about 4 or less.

    摘要: A method of fabricating a semiconductor integrated circuit (IC) is disclosed. The method includes providing a substrate having two different topography areas adjacent to each other. A step-forming material (SFM) is deposited over the substrate. A patterned SFM is formed in the low topography area of the two areas. The formation of the patterned SFM provides a fairly planar surface across over the substrate.
