    摘要: A low stress, protective coating for a semiconductor device and a method for its manufacture. A preferred embodiment comprises coating the top surface of a semiconductor die with polyimide except for corner regions of the die. Not having corners in the polyimide protective overcoat generally reduces shear stresses in the die. Reducing stress, in turn, generally reduces the occurrence of problems such as fracture, delamination, or cracking within the die. A low stress coating may be particularly advantageous in semiconductor devices having low-k insulating materials, which are generally of low mechanical strength.

    摘要: A method for forming a bottom storage node of a capacitor for a DRAM memory cell on a substrate is disclosed. The method comprises the steps of: forming a first oxide layer onto the substrate; forming a conductive contact plug in the first oxide layer, the contact plug extending down to the substrate; forming a second oxide layer over the first oxide layer and the contact plug; forming a silicon nitride layer over the second oxide layer; patterning and etching the silicon nitride layer and the second oxide layer to form a trench over the contact plug; forming a layer of rugged insitu doped polysilicon layer over the silicon nitride layer and along the walls and bottom of the trench; depositing a photoresist layer over the rugged insitu doped polysilicon layer and filling the trench; performing a first reactive ion etching step until the rugged insitu doped polysilicon layer lying on the silicon nitride layer is reached; performing a second reactive ion etching step until the rugged insitu doped polysilicon layer lying on the silicon nitride layer is removed, the second reactive ion etching step formulated to remove the rugged insitu doped polysilicon layer faster than the photoresist layer; and performing a chemical dry etching step to smooth out the sharp corners of the rugged polysilicon layer.

    摘要: This pertains generally to precursors and deposition methods suited to aerogel thin film fabrication of nanoporous dielectrics. A method of forming a nanoporous dielectric on a semiconductor substrate is disclosed. By a method according to the present invention, a precursor sol is applied as a nongelling thin film 14 to a semiconductor substrate 10. This substrate may contain patterned conductors 12, gaps 13, and/or other structures. A portion of the solvent is evaporated from the thin film 14 to produce a reduced thickness film 18. Film 18 is gelled and may be aged. A surface modification agent is introduced to the reaction atmosphere in a vaporish form, e.g., a vapor, mist, aerosol, or similar form. The surface modifier can then diffuse into, condense onto, and/or settle onto the wet gel and then diffuse throughout the thin film. This vaporish introduction of the surface modification agent ensures that there are no strong fluid flows across the wafer that might damage the wet gel. It can also be compatible with standard processing equipment and can potentially be used with other reaction atmosphere controls that reduce premature drying of the gel.
