    摘要: Disclosed is a method for precision etching of films on in-process integrated circuit wafers. The method is particularly useful for etching films comprising noble metals and is advantageous for use in constructing capacitor electrodes. The method comprises depositing a titanium nitride hard mask over the film to be etched, and thereafter patterning the titanium nitride hard mask with an etchant which is selective to titanium nitride and unselective to the underlying film. The film is then etched using either ion beam milling or reactive ion etching with oxygen as an etching agent. Both etches are highly selective to titanium nitride such that the titanium nitride hard mask can be very thin compared to the film. The presence of the titanium nitride hard mask reduces redeposition problems. Critical dimension control and substantially vertical sidewalls also result from the use of the titanium nitride hard mask.

    摘要: A pixel cell having two capacitors connected in series where each capacitor has a capacitance approximating that at of the periphery capacitors and such that the effective capacitance of the series capacitors is smaller than that of each of the periphery capacitors. The series-connected capacitors are coupled to the floating diffusion (FD) region for receiving “surplus” charge from the FD region during saturation conditions.

    摘要: A method used during the formation of a semiconductor device comprises forming a first portion of a digit line contact plug before forming storage capacitors. Subsequent to forming storage capacitors, a second portion of the digit line plug is formed to contact the first portion, then the digit line runner is formed to contact the second plug portion. A structure resulting from the process is also described.

    摘要: Semiconductor structures formed using redeposition of an etchable layer. A starting material is etched and redeposited during the etch on a sidewall of a foundation. The foundation may be removed or may form an integral part of the structure. The starting material may contain one or more layers of material. The structures are adapted for a variety of capacitor structures.

    摘要: A capacitor construction includes a first electrode and a layer between the first electrode and a surface supporting the capacitor construction. The capacitor construction can exhibit a lower RC time constant compared to an otherwise identical capacitor construction lacking the layer. Alternatively, or additionally, the first electrode may contain Si and the layer may limit the Si from contributing to formation of metal silicide material between the first electrode and the supporting surface. The layer may be a nitride layer and may be conductive or insulative. When conductive, the layer may exhibit a first conductivity greater than a second conductivity of the first electrode. The capacitor construction may be used in memory devices.

    摘要: A method of fabricating a color filter array including the removal of unwanted residual color pigments. A substrate is coated with a colored photoresist layer. The photoresist layer is patterned. The substrate is then cured. A descumming step is performed after the curing step to remove the residual pigments without causing significant damage to the remaining color filter array pattern. In another embodiment, the descumming process may be used to control or manipulate the thickness of the color filter array. In another embodiment, the descumming process may be used to modify the surface of the color filter array to be more desirable for the formation of microlenses or other layers over the color filter array.
