Abstract:
PURPOSE: A method for cleaning a semiconductor substrate is provided to prevent a metal layer from being corroded or etched even if the semiconductor substrate includes a tungsten layer by eliminating organic residue as contaminant of the semiconductor substrate while using ozone gas and deionized water vapor. CONSTITUTION: The semiconductor substrate is introduced to the inside of a cleaning chamber(S210). Ozone gas and deionized water vapor are induced to the inside of the cleaning chamber to remove the organic residue(S220). The semiconductor substrate is drawn out from the cleaning chamber(240).
Abstract:
PURPOSE: A method for cleaning a semiconductor device is provided to remove etched residues, polymers, organic metal polymers, a silicon oxide layer or a polluted silicon oxide layer in an etch process without damages of a wire material such as tungsten, aluminium, titanium or titanium nitride, and an insulating layer. CONSTITUTION: A silicon oxide layer(50) is formed on a wafer after a wire forming process is finished. A complex layer of a titanium layer/titanium nitride layer is formed as a barrier metal. An aluminium layer having the thickness of 5000 angstrom is deposited thereon. An aluminium wire pattern(60) is formed by performing a photo etch process. A cleaning process is formed on a surface of the wafer. The remaining polymer is fully removed from the wafer without a damage of the aluminium wire pattern(60) after the aluminium wire pattern(60) is formed.

PURPOSE: A method for fabricating a semiconductor device including a storage electrode of a capacitor is provided to maximize electrostatic capacitance of a capacitor by increasing a surface area of a storage electrode. CONSTITUTION: An isolation region(150) is formed on a semiconductor substrate(100). A conductive pad(410) is formed on an active region of the semiconductor substrate(100). A conductive plug is formed on the semiconductor substrate(100) by using an SAC(Self Aligned Contact) forming method. A mold is formed on an interlayer dielectric(230). A recess process is performed on a surface of the conductive plug. An electrode layer is formed on a sidewall of the mold and a recessed conductive plug(450'). A storage electrode(650) is separated by removing the electrode layer from an upper surface of the mold.

Abstract:
The present invention provides a photomask and a manufacturing method of the same. The photomask can minimize the change of CD on a light shielding pattern by not damaging the light shielding pattern in a washing process using ammonia water using an etching prevention film covering a side wall of the light shielding pattern. The photomask comprises: a transparent substrate; the light shielding pattern located on the transparent substrate, and at least containing molybdenum and silicon; and the etching prevention film covering at least the side surface of the light shielding pattern.
