    摘要: A varying-width recess gate structure having a varying-width recess formed in a semiconductor device can sufficiently increase the channel length of the transistor having a gate formed in the varying-width recess, thereby effectively reducing the current leakage and improving the refresh characteristics. In the method of manufacturing the recess gate structure, etching is performed twice or more, so as to form a gate recess having varying width in the substrate, and a gate is formed in the gate recess.

    摘要: Disclosed is a method for fabricating a cylinder type capacitor in a semiconductor device. Particularly, the cylinder type capacitor is fabricated through performing a series of processes. Among the serial processes, a cleaning process for removing a photosensitive layer remaining in undesired regions is performed before an etch-back process for forming bottom electrodes with use of the photosensitive layer as an etch mask. Especially, the cleaning process proceeds by employing one of a dry etching process and a wet etching process.
