Abstract:
A method for cleaning a semiconductor device is provided to prevent generation of organic polymer formed on the surface of a lower electrode caused by a residual organic compound by cleaning the organic compound while using an ozone aqueous solution. An oxide layer having an opening is formed. A conductive layer pattern(120) is formed in the opening. The oxide layer is removed by using a metal corrosion avoiding agent, surfactant or a LAL(limulus amebocyte lysate) solution including a mixture of the metal corrosion avoiding agent and the surfactant such that the LAL solution includes an organic compound, hydrogen fluoride ammonium, fluoride hydrogen acid and water. In removing the oxide layer by using the LAL solution, the organic compound absorbed to the surface of the conductive layer pattern is eliminated by using an ozone aqueous solution including ozone of 5~100 ppm and hydrofluoric acid of 0.001~0.02 weight percent. The process for removing the oxide layer and the process for removing the organic compound remaining on the conductive pattern are performed by an in-situ method.
Abstract:
An apparatus for manufacturing a semiconductor is provided to reduce generation of a water spot defect by performing a dry process in a state of keeping a wafer inclined. A process chamber(100) supports a wafer(10) where a photoresist is formed. Vaporized ozone is provided to the process chamber to remove the photoresist. The process chamber changes the photoresist into a water-soluble material by the vaporized ozone. A conveyer(110) conveys the wafer from the process chamber. A drying unit(120) makes the wafer conveyed by the conveyer have a tilt of 20 to 40 degrees. The drying unit removes the water-soluble material from the wafer. The drying unit repeatedly cleans and dries the wafer.
Abstract:
A method of manufacturing a non-volatile memory device is provided to prevent voids from being formed between a control gate and a dielectric film by chemically cleaning the dielectric film using an APM(Ammonia and Peroxide Mixture) solution or a chemical solution containing ozone and fluoric acid. A device isolation pattern for defining an active area is formed on a substrate(100). A tunnel insulation film is formed on the active area. A floating gate(120) having an upper surface higher than the device isolation pattern is formed on the active area. Dielectric layers(124) are successively formed along a profile of the device isolation pattern and the floating gate. A surface of the dielectric layer is chemically cleansed. A control gate is formed on the dielectric layer. The dielectric layer has an ONO(Oxide-Nitride-Oxide) stack structure.
Abstract:
A method for cleaning and manufacturing a semiconductor device are provided to obtain an ideal profile of a structure pattern by completely removing particles from the structure pattern of the semiconductor device. Particles, which are attached to a gate pattern, are removed without consuming a gate pattern containing a metal by using a first cleaning solution containing O3 water(S210). Remained particles are removed by using a second cleaning solution containing NH4OH, H2O2, and DI(Deionized) water(S220). The metal is tungsten silicide. An ozone concentration of the O3 water lies between 10 and 100 ppm. The removing process using the second cleaning solution is performed at a temperature between 0 and 50 °C. The second cleaning water contains HF.

A hardening process is implemented to the pre-baked spin-on-glass layer under a high pressure(S30). A main-baking process is implemented to the hardened spin-on-glass layer. A silicon oxide layer pattern is formed on the object(S40).
Abstract:
A method for cleaning a semiconductor substrate is provided to enhance a yield and reliability in a manufacturing process by removing fully impurities without causing damage of a metal layer pattern. An impurity removal process is performed to remove residues of a first impurity on a semiconductor substrate including a metal layer pattern by using an organic or inorganic strip solution(S10). A removal process is performed to remove the residual organic or inorganic strip solution and residues of a second impurity on the semiconductor substrate by using a cleaning solution including nitrogen(S11). Megasonic energy is applied to the cleaning solution including the nitrogen. The cleaning solution is deionized water having density of nitrogen gas of 10 ppm to 20 ppm.
