  • Patent number: 7918182
    Abstract: The temperature of a developing solution is varied depending on the type of resist or the resist pattern. The developing solution is applied while scanning a developer nozzle having a slit-shaped ejection port that has a length matching the width of the effective area of the substrate. After leaving the substrate with the developing solution being coated thereon for a predetermined period of time, a diluent is supplied while scanning a diluent nozzle, thereby substantially stopping the development reaction and causing the dissolved resist components to diffuse. A desired amount of resist can be quickly dissolved through the control of the developing solution temperature, while the development can be stopped before the dissolved resist components exhibit adverse effect through the supply of the diluent a predetermined timing, whereby achieving a pattern having a uniform line width and improved throughput.

  • Publication number: 20060207725
    Abstract: A substrate mounting table includes a plurality of passageways independently provided therein, a temperature control medium flowing through the passageways, and a gap formed between at least two of the passageways. In a substrate processing method for processing a substrate mounted on the substrate mounting table in a substrate processing apparatus while controlling a temperature thereof, a process is performed on the substrate while controlling the temperature of the substrate by flowing the temperature control medium through each of the passageways. The passageways are respectively provided in a central area of the substrate mounting table and a peripheral area located outside the central area, and the central area and the peripheral area are thermally isolated from each other by evacuating the gap so as to set the gap to a vacuum state.

  • Publication number: 20050020057
    Abstract: A method for fabricating a semiconductor device that prevents the occurrence of bowing and thickness reduction in a dual damascene method. As shown in FIG. 2(B), silicon nitride etching is performed on a semiconductor device in process of fabrication which has a section shown in FIG. 2(A). As a result, part of a copper film is oxidized and changes into oxide. Moreover, a CFx deposit is formed on it. By performing organic insulating film etching by the use of hydrogen plasma in FIG. 2(C), however, the oxide is deoxidized to copper and the CFx deposit is converted into a volatile compound and is removed.

  • Patent number: 6471782
    Abstract: A chemical vapor deposition (CVD) apparatus for depositing a low vapor pressure copper precursor onto a silicon wafer. The CVD apparatus includes a CVD reaction chamber with an interior containing a substrate holder adapted to support a substrate, such as a silicon wafer, at a predetermined position within the CVD reaction chamber. An ultrasonic nebulizer is operatively connected to the CVD reaction chamber and is adapted to connect to a source of liquid precursor. The ultrasonic nebulizer has an atomizing discharge end adapted to atomize the liquid precursor and deposit the atomized precursor onto a substrate supported by the substrate holder. A gas distribution ring is disposed within the interior of the CVD reaction chamber for discharging a directionally oriented gas into the atomized precursor to direct the atomized precursor toward the substrate. Additional embodiments and methods for depositing the precursor are described.

  • Patent number: 5740034
    Abstract: A semiconductor wafer positioner including a rotating table on which a wafer is placed and a peripheral shape of the wafer is optically detected as a first peripheral shape signal. A control section combines two half cycle components of the first peripheral shape signal, the components being 180.degree. out of phase, to obtain a second peripheral shape signal exhibiting a characteristic feature of flat orientation. A peak in the second peripheral shape signal is detected, and data in the first peripheral shape signal corresponding to the peak and 180.degree. from the peak is invalidated. A curve approximation is utilized to approximate the invalidated data to produce a third peripheral shape signal from which an eccentricity amount and direction are calculated.
