    摘要: A method for forming word line of semiconductor device wherein a lower portion of the word line on the channel region is a I-type and a upper portion of the word line is a line-type is disclosed. The method comprises (a) forming a sacrificial insulation film on a semiconductor substrate including an active region; (b) etching the sacrificial insulation film to form an I-type sacrificial insulation film pattern whereon a channel region is to be formed; (c) forming a source/drain region; (d) forming a first interlayer insulation film; (e) planarizing the first interlayer insulation film to expose the sacrificial insulation film pattern; (f) sequentially forming a insulation film and a second interlayer insulation film; (g) etching the second interlayer insulation film and insulation film using a word line mask; (h) removing the sacrificial insulation film pattern; (i) growing a gate oxide film; (j) forming a conductive layer; and (k) planarizing the conductive layer.

    摘要: A method for implanting a cell channel ion of semiconductor device is disclosed. In accordance with the method, the bit line contact region and the edge portion of the channel region adjacent to the bit line contact region in the cell region are subjected to a selective cell channel implant process two times using a ion implant mask and rest of the cell region is subjected to cell channel implant process only once so that a impurity concentration of the storage node contact region is maintained at a lower level for minimal leakage current in the storage node contact region.
