Patent ID: 7498267

Claim:
A method for forming a capacitor comprising steps of: forming a mold insulating layer with a plurality of storage node holes over a semiconductor substrate; forming a storage node on a surface of each of the storage node holes in the mold insulating layer; and removing the mold insulating layer comprising steps of: loading the semiconductor substrate with the storage node in the chamber in which a cleaning process, rinse process, and drying process are performed in an in-situ manner; removing the mold insulating layer by introducing an etchant into the chamber; rinsing the semiconductor substrate with the mold insulating layer being removed by introducing deionized water into the chamber while discharging the etchant out of the chamber; finally rinsing the rinsed semiconductor substrate with a mixed solution of deionized water and an organic solvent; drying the finally rinsed semiconductor substrate by introducing an iso-propylene alcohol (IPA) vapor into the chamber while discharging the mixed solution of deionized water and organic solvent out of the chamber; and unloading the dried semiconductor substrate.
