    • A semiconductor device has a structure of contacts whose size and pitch are finer that those that can be produced under the resolution provided by conventional photolithography. The contact structure includes a semiconductor substrate, an interlayer insulating layer disposed on the substrate, annular spacers situated in the interlayer insulating layer, first contacts surrounded by the spacers, and a second contact buried in the interlayer insulating layer between each adjacent pair of the first spacers. The contact structure is formed by forming first contact holes in the interlayer insulating layer, forming the spacers over the sides of the first contact holes to leave second contact holes within the first contact holes, etching the interlayer insulating layer from between the spacers using the first spacers as an etch mask to form third contact holes, and filling the first and second contact holes with conductive material. In this way, the pitch of the contacts can be half that of the first contact holes.
    • 半导体器件具有接触的结构,其尺寸和间距比通过常规光刻提供的分辨率可以产生的那些更小。 所述接触结构包括半导体衬底,设置在所述衬底上的层间绝缘层,位于所述层间绝缘层中的环形间隔物,被所述间隔物包围的第一接触部以及埋在所述层间绝缘层中的每个相邻的所述第一接触层 间隔物 接触结构通过在层间绝缘层中形成第一接触孔而形成,在第一接触孔的侧面上形成间隔物以在第一接触孔内留下第二接触孔,使用第一接触孔从间隔物之间​​蚀刻层间绝缘层 间隔物作为蚀刻掩模以形成第三接触孔,并且用导电材料填充第一和第二接触孔。 以这种方式,触点的间距可以是第一接触孔的间距的一半。
