    摘要: According to one exemplary embodiment, a structure comprises a substrate. The structure further comprises at least one memory cell situated on the substrate. The at least one memory cell may be, for example, a flash memory cell, such as a SONOS flash memory cell. The structure further comprises an interlayer dielectric layer situated over the at least one memory cell and over the substrate. According to this exemplary embodiment, the structure further comprises a UV radiation blocking layer which comprises silicon-rich TCS nitride. Further, an oxide cap layer is situated over the UV radiation blocking layer. The structure might further comprise an antireflective coating layer over the oxide cap layer. The interlayer dielectric may comprise BPSG and the oxide cap layer may comprise TEOS oxide.

    摘要: A liquid cleaning composition and method for removal of photoresist including an aliphatic alcohol. Preferably, the alcohol is isopropyl alcohol. Additionally, an alcohol/base mixture can be used to remove photoresist, rather than alcohol used alone. Preferably, the alcohol is isopropyl alcohol, while the aqueous base is ammonium hydroxide. The temperature conditions range from about 25 degrees C. to about 70 degrees C. The pressure conditions range from about 14 pounds per square inch to about 100 pounds per square inch.
