摘要： An integrated circuit is manufactured from a semiconductor substrate having trenches with first and second sidewalls facing each other and a conductive line arranged in a bottom region of the trenches. At least the bottom region of the trenches is lined with an insulative material between the conductive line and the substrate. A first sacrificial layer is formed above the conductive line adjacent the first and second sidewalls. The trenches are filled with one or more additional sacrificial layers having a different etch selectivity than the first sacrificial layer. A portion of the one or more additional sacrificial layers and a portion of the insulative material are selectively removed to the first sacrificial layer so that the substrate is exposed below the first sacrificial layer along the first trench sidewalls and covered by the insulative material along the second trench sidewalls.
