    摘要: A process for forming an upper-layer fin and a lower-layer fin of a storage electrode, and a semiconductor integrated circuit device fabricated by the process. When two-layered polycrystalline silicon films are to be sequentially etched to form the upper-layer fin and the lower-layer fin by the dry-etching method using a first mask, the upper polycrystalline silicon film is patterned at first so far as to form the clearance of the upper-layer fins with the minimum working size of the memory cells of a DRAM, to form the upper-layer fin. Next, the lower-layer fin is formed by the dry-etching method using a second mask which has a pattern enlarged in self-alignment from the pattern of the first mask, so that it is given a larger horizontal size than that of the upper-layer fin.

    摘要: A parallel-plate plasma etching apparatus includes a susceptor electrode and a shower electrode which are arranged in a process chamber. A semiconductor wafer is placed on the susceptor electrode. A shower region defined by a plurality of process gas supply holes is formed in the shower electrode. The shower electrode is cooled by a cooling block and causes an effective electrode portion of the shower electrode to have a temperature gradient such that a temperature at the central portion of the effective electrode portion is lower than a temperature at the peripheral portion of the effective electrode portion. The diameter of the shower region is selected to be smaller than the diameter of the wafer by 5 to 25% such that degradation of planar uniformity of a degree of etching anisotropy on the wafer caused by the temperature gradient of the effective electrode portion is compensated for. The diameter of the effective electrode portion is selected to be larger than the size of a wafer by 5 to 35% such that a taper angle of a side wall to be etched formed by etching is set to be 85.degree. to 90.degree..
