    Abstract: There is provided a process and its system for fabricating plasma with feedback control on plasma density. This process uses a heterodyne millimeter wave interferometer as a sensor to measure the plasma density in the process container and the plasma density that is needed in the plasma fabricating process, and then provides real-time information of the measurements to a digital control device which makes numerical calculations and then drives the RF power generator to change the RF output power so as to enable the plasma density in the plasma fabricating process to be close to the expected plasma density. The conventional operation parameter method is to control air pressure, RF power, gas flow quantity, temperature and so on. However, it does not control the plasma parameter that has the most direct influence on the process. Therefore, this method cannot guarantee that, in the process of fabricating wafers, different batches of wafers will be operated under similar process plasma conditions. The present invention provides a process plasma source that can be directly controlled so as to obtain process plasma source of steady quality.

    Abstract: A liquid output portion is arranged above a substrate. In the substrate, a film formation region and a non-film-formation region are determined. The liquid output portion is responsible for continuously outputting a liquid in a constant amount to the substrate. The substrate and the liquid output portion are relatively moved by a moving portion. Below the liquid output portion, a liquid shut-out portion is arranged. At least one of the substrate and the liquid output portion is moved and ready to supply of the liquid from the liquid output portion to the non-film-formation region, the supply is shut out by the liquid shut-out portion. A liquid, which has been controlled so as to spread in a constant amount, is continuously output from the liquid output nozzle to the substrate. While the nozzle and the substrate are relatively moved, the liquid is supplied to a first region on the substrate. While the nozzle and the substrate are relatively moved, the liquid is supplied to a second region on the substrate in such a way that the liquid supplied from the nozzle and spread in a second region on the substrate is in contact with the liquid which has supplied and spread in the first region on the substrate. In the case where projections and depressions are formed on the surface of the substrate, an amount of the liquid to be supplied to the substrate is varied depending upon the ratio between the projections and depressions.

    Abstract: A processing solution is supplied from processing-solution suppliers onto the surfaces of targets to be processed while a flow rate of the processing solution is being adjusted. The processing solution is fed from a processing-solution supply source at a specific pressure via a processing-solution pressure-up feeder. The pressure of the processing solution fed via the processing-solution pressure-up feeder is adjust to another specific pressure or more at least when the processing-solution suppliers are operating simultaneously. A flow-rate detector detects the flow rate of the processing solution supplied from each processing-solution supplier. A pressure detector detects the pressure of the processing solution fed via the processing-solution pressure-up feeder. The flow-rate adjuster and the pressure adjuster are controlled based on prestored control data and detection signals from the flow-rate detector and the pressure detector so that the same amount of processing solution is supplied to the targets from the processing-solution suppliers.

    Abstract: In a film deposition process wherein a plasma generation chamber is divided from a deposition chamber, radicals are extracted from the plasma generation chamber to the deposition chamber and caused to react with a process gas to form a silicon oxide film. The deposition apparatus has a host controller for dictating a pattern of control of the process gas flow to an MFC provided in a feed part for feeding the process gas into the deposition chamber. The host controller gives the MFC instructions for executing control to, in a first half side time constituting not more than half of the whole film deposition time, first make zero or limit and then gradually increase the process gas flow. The process gas flow in the first half side time can also be limited so that the thickness of film deposited in the first half side time is not greater than 10% of the overall thickness of the silicon oxide film. A silicon-hydrogen compound (SinH2n+2 (n=1, 2, 3, . . . )) is used as the process gas.

    Abstract: Apparatus and method for depositing controlled short intervals of electrostatic charge on a moving web substrate to be coated, including a mathematical model that estimates the charging performance of the apparatus. The model is constructed via benchtop characterization of the apparatus. The model is implemented in coating production via an algorithm comprising a best-fit equation representing the model predictions over a range of relevant input parameter values such as web speed, web capacitance, and desired web voltage. The apparatus includes an electrical charging apparatus, a power supply for powering the charging apparatus, and a controller programmed with the algorithm for automatically setting and controlling the intensity and duration of the output of the power supply to yield the optimal electrostatic potential on the charging apparatus. In operation, run-specific variables including web type and coating speed are also provided as inputs to the controller. The invention is useful in minimizing coating disturbances at starts and between-roll splices.

    Abstract: A method for electrostatically assisting in coating a liquid composition from a hopper to a web supported by a backing roller, characterized by the steps of a) neutralizing all charges on both surfaces of the web by passing the web through an appropriate electrostatic environment ahead of the coating point, and b) providing a uniform electrostatic field around the backing roller, which field extends through the web to engender an electrostatic “pressure” for urging the liquid composition toward the coatable surface of the substrate at the coating point resulting in an increase in the maximum coating speed achievable without onset of air entrainment at the coating point, improved thickness uniformity of coating, and a reduction in residual charge on the web after coating.
