  • Publication number: 20080165021
    Abstract: The present invention discloses an apparatus and a method for determining the voltage level of a first signal from a playback device having an interface in compliance with an industrial standard. According to the method, first receive the first signal by a signal receiving pin electrically coupled to a signal transmitting pin of the interface. Then output a first output voltage by processing the first signal by the combination of a first zener diode and a first transistor and a second output voltage by processing the first signal by the combination of a second zener diode and a second transistor. Thus the voltage level of the first signal can be determined according to the first output voltage and the second output voltage.

  • Patent number: 7083495
    Abstract: 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 3? 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.

  • Publication number: 20060001160
    Abstract: Apparatus for forming a semiconductor structure comprising a first layer on top of a substrate wherein the first layer defines conductive regions such as copper interconnect lines and non-conductive regions such as dielectric materials. The conductive regions are covered by a second layer of a material different than the first layer such as for example nickel and then the structure is heat treated such that the interconnect lines and second metal, such as a copper interconnect line and a nickel second layer, interact with each other to form an alloy layer. The alloy layer has superior qualities for adhering to both the copper interconnect lines and a subsequently deposited dielectric material.

  • Patent number: 6972253
    Abstract: 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.
