    摘要: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor structure having a plating enhancement layer.
    SOLUTION: There is disclosed a method of manufacturing a semiconductor structure comprising: a step for forming an interlayer dielectric (ILD) layer on a semiconductor layer; a step for forming a conductive plating enhancement layer (PEL) on the ILD layer; a step for patterning the ILD and the PEL; a step for depositing a seed layer in the pattern that is formed by the ILD and the PEL; and a step for plating the top of the seed layer with copper. The PEL reduces resistance over an entire wafer, and functions to facilitate copper plating. The PEL is preferably an optically transparent conductive layer.

    摘要: PROBLEM TO BE SOLVED: To suppress side etching of a film to be etched without increasing the number of processes. SOLUTION: In a substrate structure 20, a protection film 10 existing in an etching schedule region 18 is removed by ICP-RIE. An exposed region 22 where a main face 12a of a substrate 12 is exposed is formed. Namely, the substrate structure is provided with the substrate, a protection film covering the substrate, photoresist 14 covering the protection film, and a hole 16 formed in photoresist. The hole is provided with an opening 16b formed on a surface of photoresist and a hollow part 16c which continues to the opening in a thickness direction of photoresist, and reaches the protection film. ICP-RIE is performed by a condition that (1) ICP power is set to be 20 to 100 W, (2) RIE power is set to be 5 to 50 W, and (3) atmospheric pressure of an etching chamber is set to be 1 to 100 mTorr.

    摘要: PROBLEM TO BE SOLVED: To provide a manufacturing method for a semiconductor device wherein a parasitic capacitance between metallic films and short-circuit between the metallic films are restrained.
    SOLUTION: A first wiring line 203, a diffusion prevention film 205 and a second insulating film 207 are formed on a substrate in order, and a sacrificial film 213 is formed in an upper surface of the second insulating film 207. A connection hole 211 and a wiring groove 217 are formed and a barrier metal film 219 and a copper film 221 are formed on the sacrificial film 213. CMP for removing an unnecessary part of the copper film 221 and the barrier metal film 219 is carried out by two steps of primary polishing for stopping polishing in the surface of the barrier metal film 219 and second polishing for polishing the remaining barrier metal film 219 and the tapered sacrificial film 213.
