摘要:
According to a method of manufacturing a semiconductor device, hard mask lines are formed in parallel in a substrate and the substrate between the hard mask lines is etched to form grooves. A portion of the hard mask line and a portion of the substrate between the grooves are etched. A top surface of the etched portion of the substrate between the grooves is higher than a bottom surface of the groove. A conductive layer is formed to fill the grooves. The conductive layer is etched to form conductive patterns in the grooves, respectively.
摘要(中):
根据半导体装置的制造方法,在基板上平行地形成硬掩模线,并且蚀刻硬掩模线之间的基板以形成凹槽。 硬掩模线的一部分和凹槽之间的基板的一部分被蚀刻。 在槽之间的衬底的蚀刻部分的顶表面高于槽的底表面。 形成导电层以填充凹槽。 蚀刻导电层以分别在凹槽中形成导电图案。
