    摘要: A wafer based APC method for controlling an oxide (Cu, or TaN) polish step is described and combines a feed forward model that compensates for incoming wafer variations with a feed backward model which compensates for CMP variations. The method is geared toward minimizing Rs 3σ variations. A Rs target value is inputted with metrology data from previous processes that affects the width and thickness of the copper layer. A copper thickness target and polish time for the first wafer is determined. Post CMP measurement data of the first wafer is used to modify the polish rate with a disturbance factor and an updated polish time is computed for subsequent wafers. The CMP recipe for each wafer is adjusted with metrology data and post CMP measurements. The APC method is successful in controlling copper Rs variations for the 90 nm technology node and is independent of copper pattern density.

    摘要: A method for fabricating dielectric barrier layers in integrated circuit structures such as damascene structures is provided. In one embodiment, a low-k dielectric layer formed on a substrate is provided. The low-k dielectric layer has at least one opening exposing an underlying metal layer. A first silicon carbide barrier layer is formed to conformally cover the exposed surfaces of the opening. A portion of the first silicon carbide barrier layer above the low-k dielectric layer and over the bottom of the opening is converted with an oxidation treatment into a layer of silicon oxide. The silicon oxide layer is removed above the low-k dielectric layer and from the bottom of the opening. The opening is filled with a conductive layer in electrical contact with the underlying metal layer. The conductive layer is removed above the low-k dielectric layer to a predetermined depth below the low-k dielectric layer to define a recess therebelow. A second silicon carbide barrier layer is formed to cover the recess and above the low-k dielectric layer and the first silicon carbide barrier layer so as to seal the top of the structure. A portion of the second silicon carbide barrier layer above the low-k dielectric layer is converted with an oxidation treatment into a layer of silicon oxide. The layer of silicon oxide is then removed and the metal conductive layer is fully encapsulated by the silicon carbide barrier layer.

    摘要: An LCD panel including a first substrate, a second substrate and a smectic liquid crystal layer is disclosed. The first substrate includes a first electrode, a second electrode and a first horizontal alignment film. The first electrode has plural first portions. The second electrode has plural second portions. The first portions are spaced by the second portions. The electrical field directions formed between the first portions and the second portions are perpendicular to the surface of the first substrate. The electrical field direction on each first portion is opposite to that on each second portion. The first horizontal alignment film covers the first and the second electrodes. The second substrate includes a second horizontal alignment film. The horizontal rubbing direction of the first horizontal alignment film is parallel to that of the second horizontal alignment film. The smectic liquid crystal layer is sealed between the first and the second substrates.
